Subject: [q] Centris 650 Problems



I was hoping someone could give me some suggestions
for a sick Centris 650.  I had it in storage for a
while and before I put it in, it worked great.  Once I
took it out, however, I couldn't get it to turn on at
all.  It appears to be dead.  I can't get the fan to
come on or get a chime or anything.  As far as I can
tell, everything is fine.  I even pulled the SIMMs to
see if that would help.  I also replaced the PRAM
battery and nothing worked.  At this point, I am at a
loss.



At any rate, I would appreciate any suggestions or
tips anyone can offer me on getting this Centris 650
back from the grave.  I'd hate to scrap it as it's a
fine machine.


Most likely the some capacitors in the power supply or on the 
motherboard have given up the ghost.  Examine the motherboard 
carefully for a slightly dark discoloration around the area where the 
power supply plugs into the MB.   If it looks like there's a cola 
stain on there, then your surface mount electrolytic capacitors (look 
like tiny silver storage tanks) have leaked their electrolyte onto 
the board.


If the MB caps have leaked you could have three problems.  The 
electrolyte is somewhat conductive and can cause shorts.  This is 
corrected by cleaning the MB.  Some folks run them through the 
dishwasher, but I recommend a careful scrubbing with 91% isopropyl 
alcohol (or spray with Flux remover and scrub).  A soft bristle or 
worn out toothbrush is good for scrubbing.


The electrolyte is corrosive and may have eaten through traces, 
solder joints or vias (conductive holes through the motherboard) on 
the motherboard.  If this is the case, you would need to identify the 
damaged area and either resolder damaged solder joints or bypass with 
wire wrap (for damaged traces or vias).


There are about four of these caps that are important to the power-on 
circuitry.  If those caps stop working, then the machine won't stay 
on.  However, this problem more commonly has the symptom that the 
machine powers on for a moment and then turns off.  If these caps are 
dead then you need to replace them.  If you have leaky caps, you 
really ought to replace them all anyway, because they could continue 
to leak.   If you use two 15W soldering pencils (Radio Shack $10 
each) it is easy to remove the surface mount caps.  Just apply one 
pencil to each side and gently lift the cap when it comes loose.


Alternatively, your power supply may be history.  Again, the 
electrolytic capacitors in the supply are the most likely culprit, 
but this time you'd be dealing with through-hole caps rather than 
tiny surface mount caps.   Replacing the caps in the power supply 
might fix it.


You can use the power supply from the following Macs in the Centris 
650:  Mac IICX, IICI, IIvi, IIvx, Q700, C650, Q650, PM7100.


Motherboards for the Centris 650 are not uncommon on Ebay and 
generally under $15.  You can also use the motherboard from a Quadra 
650 or a Q800.   Your CPU chip is almost certainly still fine, so you 
could even get a MB with no CPU and just move it over, which might 
save you a bit.   I like the seller, Olde Mac Milt (olde-mac-milt), 
so you might contact him and see if he has a C or Q650 motherboard 
available.


Oops, just checked and it looks like he's in the process of moving.

[q] Quadra 610/ DOS problem

2005-11-22 Thread Jeff Walther

Date: Tue, 22 Nov 2005 11:57:22 -0800 (PST)
Subject: [q] Quadra 610/ DOS problem
From: [EMAIL PROTECTED]

Hello,
  Just wondering if anyone might be able to assist with a dead
Q610/DOS. Problem is that I get the 'Chimes of Death' on Boot and no
Picture on the monitor. It has 16mb of RAM and is maxed on Vram. I'd
like to get it up and running so I can get file off the HD.

Any Ideas to try?


As Ken wrote, the RAM is the first place to look.  If that doesn't 
work, I'd pull the RAM (there's 4 MB on the MB, yes?) disconnect all 
SCSI cables (internal and external) and remove anything (DOS card) 
from the expansion slot.


Then test to see if you get a proper chime.  If you do get a proper 
chime, then add things back a few at a time until the problem returns 
or until you're back in business.  This is a standard kitchen-sink 
diagnosis method.


If the stripped down machine still doesn't chime properly, then 
you've got a power supply or a motherboard problem and probably 
motherboard (power supply problems tend to manifest as dead sets). 
In that case, I'd examine the motherboard carefully for 
darkened/discolored areas.  Old Macs bite the dust as the 
electrolytic caps start to leak.   The stuff they leak is apparently 
conductive and corrosive.  If it hasn't corroded anything, then you 
cna probably get operational again by thoroughly cleaning the board. 
Some folks swear by running it through the dishwasher, but I prefer a 
thorough scrubbing with alcohol or spray and scrub with Flux Remover 
(available at Frys).  To be really thorough, replace all the surface 
mount electrolytic caps with SM tantalum caps.


If there are no discolored areas, I'd guess that the on-board RAM has 
developed a fault.  It's probably not too hard to scavenge some chips 
from old 4 MB SIMMs and replace it if you're reasonably skilled at 
soldering.  I could do it but the shipping both ways is probably more 
than a replacement Q610 board.

The quad doublers are for quadra's and centris systems. They run at double
the speed of the original cpu, up to 50mhz, so they can't be used on
quadra's with a 33mhz cpu originally. They are only for 20mhz and 25mhz 040
systems, upgrading them to 40mhz or 50mhz.

I'm not sure about the turbo 040, but I'm sure somebody else here can chime
in about them.


The Turbo 040 is for 68030 based Macs.  It works without an adapter 
in the IIci, and (IIRC) the IIvi and IIvx.  With various adapters it 
can be installed in the Mac II, IIX, IICX, IISI and SE/30.  Oh, I 
believe there's also an adapter for the LC, LCII and Color Classic, 
because I have a couple of those laying around here--okay, I checked.


This adapter puts the PowerCache in the Color Classic, LCII and the 
LC.   However, the PowerCache (68030 based accelerator, up to 50 MHz) 
generally used the same adapters as the Turbo040, so it may be 
possible to put the Turbo040 in the LC, LCII and Color Classic as 
well.


In general, the 68040 chip is very over-clockable, so I'm not sure 
that there is much point to the Quad upgrade from Daystar.  With a 
bit of soldering, the Centris 650, Q650 and Q800 can often be bumped 
up to 40 MHz.  See:http://homepage.mac.com/schrier/mhz.html

[q] q840av video Q

Date: Sun, 04 Sep 2005 13:45:24 -0500
From: Tim  Alethea Larson [EMAIL PROTECTED]
Subject: [q] q840av video Q

Hi list,

I have a couple Nubus video cards, and was wondering if either of them
gives any advantage over the built-in video of my Q840AV.  I got them
both secondhand and don't know anything about either except what is
printed on the card.

1: 8 card with RADIUS Inc 1992 PrecisionColor 24Xp printed on it.
There is also a sticker that repeats that info, and adds V1.3.2 256K
U1200 -0047-03-A.

2: 6 card with Accelerated 8-Bit Graphics I/F (C) RADIUS Inc. 1993
printed on it.  Small sticker says 632-0188-02 Rev. A4.

Both have an identical chip that says (c)1992 Radius 297-0582 4LO8F1044.
  #1 has another (c)1991 Radius chip 297-0587, and #2 has a (c)1993
Radius chip 297-0501-01.  Both have some chips that I assume are VRAM,
but no indicator how much.

I've got one slot left in my Quadra so I want to pick the better of the
two, if either is better than the onboard video.  Thanks for any info!


My guess is that the built-in is going to be better than any NuBus 
card you can install, but why don't you get a copy of MacBench and 
run the Graphics test suites and compare?


The two cards you have there are fair cards, but not among the 
fastest that were released before NuBus was abandoned.


The fastest video cards would be a Radius Thunder IV GX (1152, 1360 
or 1600), Radius Thunder 24/GT or the Villagetronics MacPicasso 340 
(not the 320).


Those might give the Q840AV's internal video a run for its money but 
I'm not sure.   And it depends on what type of applications you're 
using, of course.


The Thunder IV GX series bears a daughter card with four DSP 
processors to speed Photoshop operations.   So if you're running an 
OS earlier than 7.6 (PhotoEngine extension doesn't work on 7.6 and 
later) and you're using Photoshop, then a Thunder IV GX might be your 
best bet.


On the other hand if you want the fastest frame rates you can get in 
something like Marathon, then you're probably best off with the 
built-in video.


Absent someone who has already done the testing, the only way to find 
out is to run some benchmarks yourself.  I've run a bunch on the 
Power 120 machine (8100 clone) but I have not tested a Q840AV.

While a 9 GB capacity will work, the LC475 requires a 3.5 drive in 
1/3 height or LP.   A 5.25 drive will not fit in the case.


I'm guessing you have a Seagate Elite ST410800N.  Those were nice 
drives in their day, especially because they cost about $.40/MB back 
when hard drives generally cost about $1.00/MB.   But they're just 
too large to fit in a Pizza Box Mac.  I have one in a nice external 
SCSI enclosure.

Some work, some don't.  I'm sure it has to do with the organization 
of the SIMM, e.g. Single Bank vs. Double Bank.   However, I do not 
know which organization is required to work in the 630.


In the Q605, one needs Single Bank 64 MB SIMMs but that varies from

If some 128MB SIMMs work, then some 64 MB SIMMs should work too.  The 
trick is finding the ones that do work.


You won't hurt anything (except your pocketbook) by trying SIMMs that 
don't work.  They'll just show up as 1/2 or even 1/4 capacity.

Re: [q] Old Q950 just went out of service

2005-04-19 Thread Jeff Walther
From: [EMAIL PROTECTED]
Date: Tue, 19 Apr 2005 15:14:19 EDT
Ive done LOTS of research.  First of all, the DayStar 80MHz PowerPro has 4
72 pin slots on it, so I will definitely get at least 384MB RAM total, maybe
512 if the 64MBs will work on the PowerPro.
Ah, I missed the detail that you're looking at the PPC upgrade with 
RAM slots on board.  I had forgotten that that beast existed.  Mea 
Culpa.

Second, I know that by just
increasing the bus speed on the PowerPro, and thus the processor, it 
wont go faster
than 85 or 90MHz.  Third, I know a 100MHz 601 can make it to or almost to
120MHz.
According to IBM, the 100 MHz 601 will get to 120 MHz with cooling. 
That usually means installing a Peltier Thermoelectric cooler, which 
you will find on the various PPC601 Macs and clones built to run 100 
MHz or faster.

The difficulty with overclocking the bus speed may not be in the CPU, 
though.  It could be that the PowerPro will not sync up with the 
motherboard if its (the upgrade card's bus) speed is outside a 
certain range.   Your mention that it won't run unless the host 
motherboard is running at 25 or 33 MHz would seem to support this 
hypothesis.

My experience with the Turbo601 (also designed by Daystar and 
probably quite similar in technology) was that the card would only 
operate in a very narrow range of frequencies.  Before modifying it 
to clock triple, I found that it would only operated from about 29 
MHz to 34 MHz, which yielded CPU speeds of 58 MHz to 68 MHz.  So I 
knew the problem was not in the CPU speed tolerance, but in the card 
clock synchronization.

The PowerPro may be similar.  You should try adjusting the clock 
speed of the unmodified card *downwards* and see how much tolerance 
it has.  This will give you a better feel for whether a clock 
tripling modification will work.

Certainly, you cannot get the existing CPU chip to run at 120 MHz. 
So, if you did a clock tripling modification, and left the bus speed 
at 40 MHz, it would not work.  However, you might be able to do a 
clock tripling modification and get 96 - 100 MHz out of it, if it 
will tolerate running at 32 - 33 MHz.

Once you have a clock tripling modification working, then it would be 
time to look at replacing the CPU chip.   If you do all the 
modifications at once, and it doesn't work, troubleshooting will be a 
bear.   Of course, you could try replacing the CPU first without 
modifying the clock speed and see if you can get the replacement CPU 
chip to work.

There was also an Unofficial Home Page for the PowerPro, I believe. 
I know there was one for the Turbo601 and I believe it had a link to 
the one for the PowerPro.  That might be an avenue that could lead to 
high resolution scans of the card.

Re: [q] Old Q950 just went out of service

2005-04-18 Thread Jeff Walther
From: [EMAIL PROTECTED]
Date: Sun, 17 Apr 2005 17:46:57 EDT

The 9150 is a beautiful machine too.  Anyway, dont throw out the 16MB SIMMs,
there are plenty of people who will pay for them, myself included.  I only
have 8 of them, and I also have a Mac II so Id take all 16.  Anyway, Id like a
JPEG of the drive sled too.  If possible, Id like a high resolution 
JPEG of the
100MHz card.  I want to compare it to my 80MHz card too see the differences.
I was thinking of paying somebody to solder on a 120MHz 601 to my 80MHz
PowerPro with RAM expansion (anyone know how much this would 
cost???), obviously
some things need to be reworked.  But a 120MHz (or slightly faster) Quadra 950
with perhaps 512MB RAM would be sexy (at least 384MB RAM).
Well, you're not going to get more than 256 MB into the Q950 without 
something like a Daystar RAMCard (are those Q compatible?).  Sixteen 
sockets times 16 MB per stick is 256 MB of RAM, maximum theoretical 
capacity.

In the case of the Turbo601 (the PPC upgrade for the IIci, IIsi, 
IIvi, IIvx), it was necessary to move a couple of handfuls of 
resistors and add an ICS9178 chip in order to speed up the 66 MHz 
version to close to 100 MHz.  The ICS9178 is no longer available but 
there might be something with the same functionality and pin 
compatible available from ICS.

The ICS9178 may also be found on PM8100 (and clones) boards which are 
100 MHz or faster.

The PPC601 is a 304 pin chip with a very fine pin pitch.  I think it 
would cost you less to just find a faster upgrade card for sale, than 
it would cost to obtain a faster PPC601 chip and have it soldered in 
place.

There is also the issue that the  100 MHz PPC601s use 3.3V supply 
while the slower = 80MHz use 5V.   The LT1085 voltage regulator 
which was commonly used on PPC601 cards can be adjusted to provide 
3.3V instead of 5V by changing a couple of resistors, but it is 
another change that would be needed.   And I'm not certain that would 
take care of issues with the I/O voltages.  On the 8100 and clones 
which are 100 MHz or faster, there are a series of 3.3V to 5V buffers 
around the PPC601 chip to switch the bus signal voltages between 3.3V 
for the PPC601 and 5V for the rest of the computer.

On the Turbo601 card, I was able to get 96 MHz out of the 66 MHz 
rated PPC601 after adding the ICS9178 so that the card clock tripled 
instead of clock doubling.  If you Google up Marc Schrier's Clock 
Chipping Home Page you can read the article I wrote about it (9 years 
ago?).  I don't have the URL handy at the moment.

I think you would also find that the PPC601/120 is nearly impossible 
to find, and if you do find one from a parts supplier, it is likely 
to cost close to $100.  However, you might be able to salvage one 
from a 7200/120 or a CPU card for the PowerCurve (PCC predecessor to 
the PowerCenter), which used a 120 MHz PPC601).  But that would mean 
a successful desoldering job as well as a resoldering job.

Anyway, it's a worthy project to try upping the speed of the 80 MHz 
upgrade, but I think that replacing the CPU chip is too ambitious. 
You should first focus on whether the slower card can be modified so 
that the PPC601 clock triples instead of clock doubles.

 I havent been on the quadlist for probably a couple of years now, but I
 just cleaned out my closet, and now I wanna get my Quadra 950 back up and
 running.  One of my first questions, which Im sure has been asked 
many times (I
 know it was a few years ago), will 32MB SIMMs work in a Quadra 950?
32MB 30pin SIMMs? Never seen any advertised. Were such things made?
Nope, no such thing.  The original poster seems a bit confused on 
what type of SIMM socket the Q950 bears.  An easy mistake to make, 
because all the later Quadras used 72 pin, but the Q700, Q900 and 
Q950 used 30 pin SIMMs in banks of four.

Thirty pin SIMMs have twelve address pins.  Addressing to RAM is 
multiplexed in row and then column, so the total number of address 
bits possible is 12 X 2 = 24.  Twenty-four address bits can address 
16M addresses.  Thirty pin SIMMs have 8 bit (one byte) wide data. 
So 16M addresses yields 16M X 1 byte = 16 megabyte maximum possible 
capacity.  No larger 30 pin SIMM is possible.

Hi all i have just come across my old Lc 475, in my shed on inspection
it has a 2gb hdd a 12mb ram and system 7.5 loaded there is a 14
monitor with it and an ADB mouse but no keyboard. (so i need one of
these) what is  a good use for this mac as i hate to see things go to
waste and i am sure i can find a place for this in the home some where.
I'm not much good at thinking of specific uses for older Macs, but if 
you do come up with an idea, and feel that there is too little RAM in 
the machine, the LC475 can go to at least 132 MB of RAM.  Apple's 
official upper limit is 36 MB with a 32 MB SIMM installed, but folks 
have put 128 MB SIMMs in this model and had them work.  It can be a 
bit tricky to find the right type and one that will fit physically 
though.

Personally, I've installed up to a 64 MB SIMM in this model.   The 64 
MB SIMM must be Single Bank rather than Double Bank.  I'm not sure 
what those terms mean, but a decent memory seller should.

The Q950 needs 30 pin SIMM's used to be used also in old PC

total, with 4MB modules you get 64MB.
One can also use the 8MB and 16MB modules (the biggest 30 pin SIMM that I

16 MB is the largest 30 pin SIMM possible.  The 30 pin SIMM has 
twelve address lines.  Addressing to RAM is multiplexed into row and 
column addresses, so the total address bits is 2 X twelve = 24 bits. 
Twenty-four bits will address 16 million addresses.   There is one 
byte of memory per address on a 30 pin SIMM (four bytes per address 
on a 72 pin SIMM, and 8 bytes per address on a 168 pin DIMM) so you 
get 16 million addresses X 1 byte/address = 16 million bytes maximum 
or 16 MB.

The last time I checked, sets of four 16 MB 30 pin SIMMs were being 
sold on Ebay for about $25.  That was a couple of months ago.

A couple of years ago, a user with the handle Sunyuk or sunguk or 
something similar to that was selling sets of four 16 MB SIMMs for 
about $15 per set.  His Item Description said they were salvaged from 
Quadra 700s and were low profile.  I haven't seen him around in a 
while though.  His sales were fixed price sales with 100s of sets 
listed as available, so I thought he would be around until I was 
ready to buy.   Sigh.

[q] A Major QuickTime Question

2005-02-23 Thread Jeff Walther
Date: Wed, 23 Feb 2005 12:51:17 -0600
From: Daniel Palka [EMAIL PROTECTED]

Quicktime has been around longer than AV Macs.  So how, in the days
before the Quadra 840av, how in gods name did they import video into
Macs to make those early QuickTime movies?
I searched for like nubus cards, scsi boxes, anything that would be
able to import video, but I'm not turning anything up.
How can I import video to my Quadra 900 or 800 from my standard analog
camera?  There has to be a way.  I really want to do this just for fun,
so any pointers would be much appreciated.  Thanks
Video Vision Studio by Radius.  It was $3000 - $4000 back when.  You 
can probably pick one up on Ebay for $25 - $50 now days.

The VVS captures in Motion JPEG.  I'm not clear on how that converts 
to QuickTime or if that is a format that QuickTime can handle, but 
I'm sure it is or was doable.

IIRC, the latest OS you can use with the VVS is 7.6.1 and I think 
that it won't work with G3 accelerators on (e.g.) the NuBus 
PowerMacs.   But those memories are vague.   The discussions about 
five or six years ago here: 
http://www.wwug.com/forums/radius/index.htm were good.   I don't 
know if this link is still good 
http://home.earthlink.net/~radse/page12.html but IIRC it had some 
good stuff.

Configuring the VVS to get good 30 fps capture was apparently 
something of an art.  You'll probably want a JackHammer card to go 
with it.

Re: [q] Micronet SEIV help

2005-01-18 Thread Jeff Walther
From: Casolai ! [EMAIL PROTECTED]
Date: Tue, 18 Jan 2005 03:12:02 -0700
I recently got a Micronet oem version of the ATTO Silicon Express IV card on
ebay. The Micronet firmware allows the card to be bootable, but is very very
buggy. It causes my 840av to lock up a lot and is driving me up the wall.
Speed on the card is excellent, with 17.6 MB/s transfers, but that speed is
useless if the system keeps crashing.
Anybody know a way to reflash the card to the ATTO firmware? I have the
1.6.5 ATTO firmware update, but when I run it, it cannot find any ATTO cards
(Micronet firmware removes that name). If I tell the ATTO updater to
manually update the nubus slot its in, the updater crashes...  ATTO tech
support gave me the cold shoulder and said they don't support old products
like that anymore. I emailed Micronet, but they haven't answered, and I
can't find any firmware updates on their website.
If anybody has any idea's for help, I would appreciate it.
Did you get that from Macguy10 or something similar?  I just bought 
one on Ebay but it won't arrive for several days.  I don't recall 
anything in the item description saying it had Micronet firmware 
though I might have skimmed over that.

Anyway, if it is the same deal, I will work on a brute force hardware 
solution and if it works, I'll let you know.  Many times these 
flashers will work if the Flash chip is blank, but not if it has 
other firmware on board.   I can desolder the flash chip, store it's 
current contents to disk on my EEPROM programmer, erase the chip, 
and then reinstall the chip to see if the Atto flasher will work on a 
blank chip.  If it won't work on a blank chip, we'll need to see if 
we can hack the firmware resource out of the Atto Firmware updater.

[q] External Storage Solutions for 'Centris 650'

Subject: [q] External Storage Solutions for 'Centris 650'
Date: Thu, 28 Oct 2004 13:35:15 -0700

 So thanks to a good buddy, I have a Centris 650,
 I noticed this box has some sort of external scsi port. I don't know much
about scsi  and am really unsure of what would be the right external drive
to get (my experience on the PC has always been match the drives to the
card, like Ultra-Wide for example) and also where to get it. Somebody told
me it was possible to connect an oridinary IDE disk to some adapter
circuitry and use that with an old mac. I've googled but haven't find this
yet. Is there such a thing? Do you guys know where the drive compatibility
information is at? Would eBay be the only place to pick up a disk or is
there a supplier?
If you want to learn more about SCSI, try http://www.scsifaq.org.
The Centris 650 has a 50 pin narrow unenhanced SCSI port.   That 
means that its top theoretical speed is 5 MB/s.   This is rather slow 
by today's standards, but is acceptable for the older, smaller, more 
compact software that one typically uses on a Centris.

With few exceptions, any SCSI drive with a 50 pin connector should 
work with your machine.Be careful, because there are a number of 
folks in the Mac categories on Ebay selling 50 pin drives which are 
really 80 pin (SCA) drives with an adapter attached.   Such adapted 
drives might work, but they can cause severe headaches because there 
are several termination issues when using adapted drives.

If you want to replace your internal drive with a larger one, simply 
buy a SCSI drive mechanism with a 50 pin connector, configure the new 
drive properly for termination and SCSI ID, format it using a Mac 
hard drive formatting utility (if it is not an Apple branded drive, 
you will a need third-party utility for this, Apple's included 
utility will not recognize the drive), such as FWB's Hard Disk Tool 
Kit (HDTK) or Intech's http://www.intechusa.com HD Speedtools. 
There are also older utilities such as from Charismac and such which 
work with the older System software.

If you want an external drive, you'll need to get a SCSI drive which 
is installed in an external enclosure or buy a drive mechanism and an 
enclosure and assemble them yourself.  The external enclosure 
provides a power supply to the drive and converts from the drive 
mechanism's internal-type ribbon cable to the external-style cabling 
used when moving around outside the computer box.

There are adapters available which convert an IDE drive into a SCSI 
drive--or rather translate a SCSI bus into something an IDE drive can 
understand.   Try the AEC-7720U from Acard.   This unit converts from 
IDE to a narrow SCSI connection (50 pins).   It has a top data rate 
of 20 MB/s (Narrow Ultra-SCSI) but that's okay because Ultra-SCSI is 
backward compatible with the Centris's unenhanced SCSI--or should be. 
I haven't actually tested this particular configuration.

The only advantage of going the adapter route is that it will let you 
put a truly huge inexpensive IDE  drive on your old machine. 
However, IIRC, the Centric needs its hard disk volumes partitioned 
into pieces of 2 GB or smaller (or is that just the boot volume?). 
So you might have a bit of trouble, if you find yourself partitioning 
a 160 GB drive into eighty 2 GB partitions.

The Centris 650 has three NuBus expansion slots (now obsolete, no new 
cards available).   There were never any IDE cards made for them. 
However there were a couple of Fast  Wide (not UltraWide, just Fast 
 Wide) SCSI cards built which are still available on the used 
market.   The primary choices were the FWB JackHammer and the Atto 
Silicon Express IV (SEIV).   Note that there was a later PCI 
JackHammer, so be sure you're looking at Nubus cards if you shop for 
a JackHammer.

These SCSI cards will let you conveniently connect 68 pin drives to 
your machine and they have a theoretical transfer rate of 20 MB/s.

Another option is to get a removable media drive.   Such drives are 
slower than hard drives but can be convenient.  I'm no fan of ZIP 
drive because of their reliability issues but an external SCSI ZIP 
drive would probably be easy and cheap to find.

Personally, I prefer the Fujitsu Magneto Optical (MO) drives.   A 
disk about the physical size of a ZIP disk costs $8 - $15 and holds 
640 MB of data (more than 6 times what a ZIP holds at less than 2X 
the price) and is extremely reliable.   You might look for the 
Fujitsu DynaMO 640 if interested.   There is also a 1.3 GB model, and 
I think it was available with a SCSI interface, but I've occasionally 
seen the DynaMO 640 for under $20.

I hope that helps,
Jeff Walther

Jeff, they were as of last week. Dutch auctions.
Ah, here it is from last week or maybe the week before (ended July

22 available (but no bids were submitted) by dutch auction starting 
at $5 each.   Shipping was quite reasonable too.   Something like $6 
or so for the first plus $1 for each additional item.   Seller is 
asante-auctions.   There are none currently listed.

Back at the end of March they mistakenly listed the 10/100 NuBus 
cards for $1 each (which is the price at which they're starting the 
PCI cards) and after that auction ended, when I asked, they said they 
had sold all of them and had actually listed more than they had by 
mistake.

I guess they found additional stock.

 Yes, the Asante 10/100 cards are going cheap on eBay. My only gripe is
 10/100 cards in any Nubus Mac either 68k or PPC still get jack for
 network through-put. Any pci Mac including a even  a 7200/75 with its
 onboard 10BaseT will smoke a Nubus Mac with a 10/100 card. At least
 thats always been my experience.
 Chris Wood
Have you done any real benchmarks?
Nubus slots up to the 840av are 32bit 10Mhz for 40MB/sec bandwidth, Nubus 2
on the 840av and the PPC nubus machines should be double that. So from those
numbers the bus should not be a bottleneck (PCI bus is limited to
132Mb/sec). If your using old 200MB scsi hardware I could see the HD being a
bottleneck.
Actually, the 840AV is still 10 MHz for 40 MB/s theoretical maximum 
throughput.  The 840AV only supports 20 MHz for card-to-card 
communications where both cards support 20 MHz and where someone 
actually wrote software support for card-to-card communications.

I don't think anyone ever built any hardware that took advantage of 
that capability.

Communications from card to 840AV and from 840AV to card are still 10 
MHz.  This is documented in the Hardware Developer Notes for the 
840AV from Apple, Centris_660AV_Quadra_840AV.pdf.

BTW, are the 10/100 cards still going cheap on Ebay?   Asante was

 So you are saying that the CPU of a 650 can just be
 popped out, and placed let's say in a 575? I thought
 these chips were soldered on.
Yes, they all use the Motorola 68040 and those puppies are consistent 
in their pinout.   There might be some machines (laptops, e.g.) where 
the 68040 is soldered down, but in all the machines where they're 
socketed, they're swapable.

The only caveat is that a slower rated chip may not run well at 
higher speeds, but my experience and the wisdom on the internet is 
that even the 25 MHz 68040 clocks up to 40 MHz quite happily.

From: [EMAIL PROTECTED]
A quadra 650 and it's cousins have a 25mhz processor - the 575 has a 33.
I got a Quadra 800 board and swapped its chip in to the 575 - things
worked fine.  -  Dick
The Quadra 650 has a 33 MHz processor.  The Centris 650 has a 25 MHz 
processor.  The Quadra 610 has a 25 MHz processor but usually a 
68LC040 w/o the FPU.  The Centris 610 has a 20 MHz processor.   The 
Quadra 800 has a 33 MHz processor and the motherboard is essentially 
identical to the Centris and Quadra 650.   The Quadra 840/AV has a 40 
MHz processor and it is a whole different animal motherboard-wise but 
the CPU will still swap out.

Where would be the best place to look for a real 68040, not its FPU-less
sibling???
Look for Centris 650, Quadra 650, and Quadra 700 motherboards.   They 
are often (or were a year ago when I was looking) available for under 
$10 and carry a CPU with the FPU.Just make sure that the seller 
is selling it with the CPU still installed.   Sometimes a seller 
sells the board sans CPU.

Re: New printer for Mac 637CD

2004-01-18 Thread Jeff Walther
Date: Sun, 18 Jan 2004 07:51:41 -0600
From: Jim Raper [EMAIL PROTECTED]
Subject: New printer for Mac 637CD
Hi, Listers,

Can someone tell me about a printer other than the old StyleWriters that
I can use on my 637CD.
I've upgraded the RAM to 64MB and installed a 3 gig HD. It is running OS
8.1 flawlessly. BUT the old StyleWriter 2400 is shot. Is there a
modern HP or Epson printer that can be used on this machine?
I have recently been through a circus getting an inkjet printer for 
our house.The issues were to get the best printer I could while 
still being compatible with at least back to OS 7.6.1 and preferably 
networkable because I like to have all my printers networked.   The 
house is well wired, so networked printing is convenient.

The current crop of inkjet printers (and printers in general) do not 
have serial ports.   They have USB ports and a good many of them 
still come with a parallel port.   There are no USB cards or adapters 
for the 637CD nor for any other machine which lacks Cardbus and PCI 
slots.

1)  So, you could get one of the adapter kits that lets you connect 
your Mac to a parallel port printer through the Mac's serial port. 
The thing is that the kit must come with a driver for your printer or 
for a language that your printer understands.   I think one such kit 
was called the Orange Grappler?

2)  Another option is to get a printer with a network port.  Now days 
that means an ethernet print server or ethernet card.  This can get 
expensive but it can also be very convenient.   A printer which is 
$70 by itself seems to suddenly gain $150 in price the moment you add 
an ethernet adapter.I miss affordable LocalTalk printers, which 
USB killed.   Darn USB.  USB isn't a network media, so it's silly, 
but there you go.   Of course, you need either an ethernet card in 
your 637 or a LocalTalk to Ethernet bridge such as the Asantetalk in 
order to connect your 637 to an ethernet capable printer.

The last time I checked, Epson had one of their network ready 
printers on their clearance list for a decent price, but I think it 
was wifi rather than cabled ethernet.

3)   Get an older printer.Here, your choices branch again into an 
older printer with a serial port or an older printer which is 
networkable.

A)  Older printer with a serial port.   For example, the Epson Stylus 
Color 850 was pretty nice and it has a serial port.   But, it's 
resolution is only 1440 X 720 which is not so good by today's 
standards.   It's fine for text.   It's not so great for printing 
photos, but okay.   You could check Epson's documentation to find the 
highest resolution printer which came with the serial port and then 
buy that one on the used market.

The 850 BTW, often goes on Ebay for under $20, but the shipping is 
about $20.

B)  An older printer with a network port.   Many of the older 
printers have a LocalTalk port, which looks like a serial port but 
functions differently.One line of the Epson inkjet printers has a 
Type B slot which is a proprietary Epson slot, but the cards are 
fairly available on the used market.  The Type B slot can take a 
LocalTalk card, any of several models of ethernet card (including 
10/100) and a few other cards which aren't relevant when you have a 
637 on the other end.

For example the Epson Stylus Color 980 (there is also a very 
different Stylus Photo 980)  has a type B slot and prints at 2880 X 
1440, which is much nicer than the 850.   It's also faster.   One can 
install the Epson LocalTalk card or any of several ethernet cards in 
the B slot.   The 980 only has USB and parallel, so you can't connect 
it to an older Mac without a network card of some type.

The documentation for the 980 claims that it requires OS 8 or 
greater, but that's because it only has the USB port and the USB 
support requires OS8 or greater on the Mac.  Once you install a 
network card, it works at least back to 7.6.1.

4)  If you have a more modern Mac, you can buy a more recent printer, 
connect it to your recent Mac through USB or Firewire (depending on 
the printer) and then Share the printer on your network using the 
software for the printer which allows this.   Again, this requires 
that your 637 be on a network with your other Mac.   It also requires 
that the modern Mac be turned on whenever you wish to print to that 
printer.

Jeff Walther

P.S.  In my case, I collected five Stylus Color 850s on Ebay 
intending to make one or two good working ones, and then found an SC 
980 at Goodwill which works perfectly...

Mactracker states that there is no ethernet for a 637cd. there may be a

Doesn't the 637 have an LC PDS slot?  It's basically a Q630 with 
different accessories and maybe an LC 68040 instead of a full 68040. 
And LC PDS ethernet cards are slightly more expensive than dirt.

Re: Upgrade LC475

2003-12-23 Thread Jeff Walther
Subject: Re: Upgrade LC475
From: stew [EMAIL PROTECTED]

 I've always wanted to max out the RAM but have been uncertain as
to what max is.  32 Mb per Apple specs but as one list member has
reported, on this very list, has used more.
I have installed 128 + 4 MB of RAM in the Q605/LC/P475/6.   I used a 
pair of Single Bank 64 MB SIMMs in a SIMMverter which is a card that 
converts one SIMM slot into two.   Grand total of 132 MB of usable 
RAM.  Of course, I couldn't close the case with the SIMMverter card 
installed.   :-)

I think someone else has reported that a single 128 MB SIMM works. 
Those can be hard to find.

Installing just a single 64 MB SIMM in the slot also worked giving 68 
MB of RAM total.   One thing to keep in mind is that the 64 MB SIMM 
must be Single Bank, not Dual Bank.   At least, that was my 
experience.  If your memory seller doesn't know what that means, find 
a different memory seller, preferably one who will let you exchange 
it if it doesn't work.

Re: What does this port on a Quadra 700 do?

2003-11-29 Thread Jeff Walther
From: [EMAIL PROTECTED]
Date: Sat, 29 Nov 2003 21:12:00 -
Subject: What does this port on a Quadra 700 do?
Message-ID: [EMAIL PROTECTED]
There's a port on the Quadra 700 which I have not been able to identify.
It has an icon that looks like this:
...

but doesn't look like a standard RJ45 Ethernet port. It has about seven pins
on the top and on the bottom of the connector.
What does it do?
It is the ethernet port.  As you may know, ethernet used a variety of 
possible cabling schemes back when.   There was thicknet, thinnet 
(forms of coaxial cable) and unshielded twisted pair (UTP, AKA 
10baseT).

Because you didn't know what kind of cabling a place would be in use, 
it was difficult to build ethernet into a computer and be certain 
that it would be compatible.   So the industry standard solution was 
an AUI port.  This is a DB15 port to which the appropriate 
transceiver could be attached, which would convert the AUI port into 
thicknet, thinnet or UTP.

When Apple started building in ethernet they created a new port 
called an AAUI (Apple AUI) which has the virtue of being smaller than 
an AUI port and the other virtue that it is not identical to Apple's 
video port which also uses a DB15.

That funny little port you're looking at is an AAUI port.   To 
convert it to UTP, which I assume would be your goal, you would need 
a transceiver.   They were made by the usual network equipment 
suspects, Apple, Asante, Dayna, Farralon, etc.   Back when, they cost 
about $70.  These days you should be able to get them for under $5 on 
Ebay plus shipping.

Some ethernet cards were also made with AAUI ports and many of the 
early cards for the Mac included an AUI port with the DB15 connector. 
One of Asante's NuBus cards has a BNC, RJ45 and AUI port all on the 
same card.  Apple's LC slot ethernet card has an AAUI port and 
requires a transceiver.

The Asante transceivers often show up on Ebay under the title Asante 
Friendly-Net Transceiver or something like that.

Re: MicroNet NuPort II SCSI card - anybody know how this works?

I've got an old (circa 1991) MicroNet NuPort II SCSI card that I'm trying to
test the capabilities of.
Trouble is, I can't find ANY documentation or useful info about it on the
web.  I have no documentation or software, just the card.

As for documentation, has anyone got a manual they could scan or photocopy?
If the documentation does turn up, and for folks in the Austin, TX 
area, there are two of these cards (as of a week ago) in the SCSI 
card bin (behind the counter) at the Goodwill Computer Works store. 
I think they're priced at $5 or $10 each.  I keep being tempted, but 
knowing nothing about them, I've left them in the bin.  I vaguely 
remember seeing them advertised or perhaps reviewed in old MacWorld 
or MacUser issues, but I disposed of my old issues many years ago.

I guess I could go down to the UT library which has back issues...

I really cannot imagine needing more than seven SCSI devices...
CD-ROM, M.O., Printer, Scanner...  This still leaves three for hard

Let's see, CD-ROM, CDRW, DVD (unlikely because I don't think there's 
an MPEG2 decoder for the NuBus PM), MO, scanner, two DAT DDS2 drives 
(because I'm cheap, but big hard drives have outgrown DDS2 tapes), 
plus hard drives, and printer if one has one of the old GCC (?) ones 
or that single Apple model.

I do like using a separate CD-ROM and CDRW.  And I already have DAT 
DDS2 but hard drives have outgrown the 8 GB compressed capacity, so I 
pretty much need at least two on the chain, so that Retrospect can 
automatically continue on the second one.   I've never had a SCSI

But in practice the hard drives would be on the JackHammer...

I have tested CD-ROMS on the internal and the external buses, both drives

From: Derek Morton [EMAIL PROTECTED]

I am looking at
making a memory card which allows the system to run full bore at zero
wait states (RAM and ROM).  Think of it as a cache card on steroids.
There are a couple of problems, one of which is that the memory is not
cheap and I have already dropped a bundle getting a stick of high speed
SRAM (0 wait states up to 50 MHz and 8 MB worth if I remember
correctly).  This surely will not be sufficient for any real-world
application, but it will show the maximum performance of the system.
That is a very cool idea.  And a very expensive idea.   I've been 
watching Ebay for over a year for some inexpensive SRAM and little 
has turned up.   The prices from distributers are scary. 
Fortunately for me, I don't need anything as fast as you do.

Is the zero wait states based on the speed rating of the SRAM or are 
there other specifications that you must take into account?   50 MHz 
is a 20ns period, so are you looking at 20ns SRAM?

My current plan is to make the PDS card first (those connectors were
IMPOSSIBLE to find
Did you find some?  Or did you decide on a work around of some kind? 
I had a similar problem when I was looking for the CPU connector for 
the x500 PMacs.  AMP has about 300 in stock, but their minimum order 
is 1008 at $9 each and all the distributers are out of stock.   But 
for $9072 they'll run off another batch of 1008 for me...

and I will have the card (once programmed) replace the
ROM on boot.
So you need to write some kind of utility to redirect the ROM reads 
to your SRAM card, plus add/modify the actual ROM code.   That's the 
part that is a complete mystery to me.   I wouldn't know where to 
begin, except at the beginning of several years of study of Mac 
programming.

 make a ROM SIMM.
I agree that a ROM SIMM is much better than replacing the motherboard 
ROMs.  It's just that getting the .050 board  seems to be difficult 
these days.  Will you be etching your own boards?

I have been doing electronic system design for years (it is my
profession) and while the ROM mods do present a challenge, I feel
confident it is quite doable.
I always believe these things are doable.  The trick is having the 
skills to do it.  It's very neat that you do.

As to my current board mods...
I have replaced the SCSI and ethernet controllers.  The new features
are simply waiting for some code to release their potential (along with
new crystals).
Did you put in a 53CF96 for the SCSI chip or something more advanced? 
The CF would give you the potential for Fast SCSI instead of just 5 
MB/s and I think it's pin compatible with the existing 53C96. 
However, the part is very hard to find and rather expensive 
($25/chip)--at least it was a couple of years ago.   There was a lot 
of 10 or so of them on Ebay in the last year or so.   Did you pick 
those up, if this is the chip you're using?

What did you do to the ethernet controller?
Thanks for the info on the ROM SIMM pin-out.
You're welcome.   It was tiny compared to the other stuff you're 
doing.   I made a small error.   Replacing the ROM chips on the 
motherboard with 2 Mb chips wouldn't work, as they're 4 Mb chips.   I 
was thinking in terms of pinout and you can't get a 4 Mb chip in a 40 
pin package, so my brain settled on 2 Mb.   I doubt this mistake 
would cause you any trouble even if it went unnoticed, becuase you 
won't be replacing the motherboard chips, but it's best if I mention 
it.

Subject: Re: hi

My Q610 also has an LC.  Apparently the FPU emulation is not stable
enough to warrant use of any *nix on the US versions of the Q610?
I would like to put a full '040 in mine also.  Any suggestions where to
pick one up?
I've seen a few of them in the Apple section on Ebay.  I think in the 
Vintage section, but perhaps in the Motherboard section.  They also 
turn up occasionally in the Electronic Components area (under 
Business and Industrial).

In many cases it's cheaper just to buy a Q700 or Q650 motherboard and 
salvage the chip from it.   The shipping is more, but you have this 
nice pin protector surrounding the chip...

Daystar Cache Speed

2003-09-30 Thread Jeff Walther
I recently bought a small lot of IIsi parts on Ebay, but the cache 
card included in the lot is clearly a Quadra cache rather than a IIsi 
cache.   This was actually a good thing in my opinion.

Anyway, the cache is from Daystar.  It has the narrow Quadra PDS 
connector on the bottom.  It has a sticker on it saying 25 MHz.   My 
goal is to take a C/Q650 board up to 40 MHz at least.   Does anyone 
have any experience with these caches as to how limited they are to 
the labeled speed?

It looks like I could replace the SRAM chips and tag RAM chips with 
faster parts I have around, but the four PAL/GALs would be a problem, 
since there's no way of knowing their contents.

From: Derek Morton [EMAIL PROTECTED]

You could always remove the GALs  and try to extract the program...
I have a Needham EMP-30 programmer http://www.needhams.com/e30.html 
but have not programmed or read any PLDs.  Is reading the program in 
a PLD a normal/common function for a universal chip programmer?   I 
may need to get the PLCC adapter...

If
they were not protected you will be fine (just don't overheat the
devices or you will ruin the program).
Overheating is something I have been wondering about.  Are PLDs more 
heat sensitive than other chips?   I'm good at soldering and 
desoldering.   I've taken 208 pin PQFPs off of boards and moved them 
to others (Hammerhead, Bandit on the PMac x500 series) without 
damaging the chips.

However, I desoldered a couple of GAL16V8's off of the accessories to 
my Outbound Laptop 125 (SCSI adapter, external floppy controller) and 
I think I burned them.   This was before I had a programmer of my 
own.  I sent them to a fellow I found on 
comp.sys.ibm.pc.hardware.chips (well there isn't an analogous Mac 
group) to have them read and he couldn't get a thing off of them. 
When he returned them and I tried reinstalling them (I had put in 
sockets in the meantime) on power up, they don't function and the 
chips grow quite warm.

My goal was to build some copies of the SCSI adapter and the external 
floppy for the Outbound Laptop.  I've obtained two more of each 
accessory, despite their rarity.   But I'm frightened to attempt 
removing the GALs for fear that touching them with the soldering 
pencil will clear/destroy them.

At this point, I'm afraid to take a soldering pencil near any PLD, 
until I get more information.  Do you have any experience desoldering 
PLDs?

Am I correct in believing that even if the PLD is protected, if it 
was programmed only in combinational mode it's not too hard to 
determine the programming.   It's when the thing is a state machine, 
that it becomes difficult or impossibly complex.

The GALs themselves are
standard 16v8 / 20v10 parts (if memory serves), but the speed will
likely be a problem if you try running it at 160% of it's rated speed
(much like the SRAM).  I have both a 25 MHz and one or two 33 MHz cache
cards, but where there are in my piles-o-stuff is another question, if
I can (easily) find them I will let you know the speed ratings of the
devices.
I compared my 25 MHz Quadra cache with the cache module for the 
Daystar Turbo040.   They're built with similar SRAM and tag RAM 
chips, and both use four PLDs.   However, the Turbo040 cache, which 
is built to go to 40 MHz uses faster parts in all three categories. 
So I suspect that you are correct, and even if I change the SRAM and 
tag RAM, the PLDs still won't keep up.

GALs are a very bad thing for us vintage Mac users.  People worry about
eventually not being able to get power supplies or pictures tubes, when
they should also be concerned about what is going to happen when the
program in their computers GALs degrades to the point of corruption.
Modern devices have a fairly long program life, but some of the older
chips were only guaranteed for around 20 years (although hopefully they
will last much longer than that).
It would be quite a job to go around and remove samples of all the 
GALs and read and store their contents.   Especially if protecting 
them was common practice.

Realize that the performance boost from this type of cache card is
minimal.  Since there is no true cache controller in the system (unlike
the 68030), these cache cards are (I believe) single segment,  fixed
memory space write-through caches which probably sit at the bottom of
the system memory and help most with system calls.
It might not be worth the effort then.   I just figured I'd have 
something to put in that PDS slot.  I'm not interested in a PPC 
upgrade, as these days, if I want a PPC, it's much cheaper and 
convenient to just get an x100 machine.   Daystar did an amazing job 
of engineering its upgrades, but they still come with a bunch of 
compatibility details one must track to use them efffectively with 
things like the JackHammer card and later OSs.

Thanks for all the information.  I hope I have not overwhelmed you 
with additional questions.  My biggest wonder at this point is about 
the practicality of desoldering PLDs without damaging them.

Re: SCSI Manager 4.3 and the Q900/950?

2003-09-29 Thread Jeff Walther
Date: Mon, 29 Sep 2003 17:25:19 +0300
From: Artur Yelchishchev [EMAIL PROTECTED]

But I have another question: where that SCSI Manager 4.3 extension can
be found?
I did a search on my computer on SCSI Manager and found some 
information I didn't know I had.  According to Inside Macintosh, 
volume Devices, section SCSI_Manager_4.3.pdf,

SCSI Manager 4.3 is an enhanced version of the SCSI Manager that 
provides new features as well as compatibility with the original 
version. SCSI Manager 4.3 is contained in the ROM of high-performance 
computers such as the Macintosh Quadra 840AV and the Power Macintosh 
8100/80. Beginning with system software version 7.5, SCSI Manager 4.3 
is also available as a system extension that can be installed in any 
Macintosh computer that uses the NCR 53C96 SCSI controller chip.

So, I believe it was first included with OS7.5 (isn't 7.5.3 a free 
download these days?) but, and this was also told to me by a Daystar 
engineer many years ago, SCSI Manager 4.3 is included in the ROM of 
Macintoshes including and after the Quadra 840AV.  Certainly the 
NuBus PowerMacs all have it in their ROM.

The Q700 and Q900 do use the NCR 53C96 SCSI controller chip.  I think 
that most of the Mac II series used the NCR53C80 but SCSI Manager 4.3 
seemed to work okay on them when I had a JackHammer card installed, I 
think.   My memory is hazy on that.

The reason I discussed this with a Daystar engineer is that the 
Turbo601 PPC upgrade for the IIci has what amounts to PM 6100 ROMs on 
board.  If you load the SCSI Manager 4.3 extension when using the 
Turbo601 upgrade it can mess with an installed JackHammer card, so 
Daystar recommends not loading the extension.   I think there was 
another detail as well, but I sold the Turbo601 a long time ago so 
stopped worrying about its byzantine compatibility requirements.

Re: 2 LC475s

2003-09-29 Thread Jeff Walther
From: Joseph Smith [EMAIL PROTECTED]
Date: Mon, 29 Sep 2003 14:37:36 -0400
Hi. I just picked up 2 LC475s from a local computer place. snip Does
 anyone know of a good place on
the web that I could pick up a set? I looked at eBay, but wanted to see
if there was anything cheaper first.
The shipping is probably more than the items are worth.  For things 
like this, it is good to state your geographical location.  That way 
if someone knows of a local supplier you can skip the shipping costs. 
For example, in Austin, TX, the Goodwill Computer Works store has a 
bunch of Extended Keyboard IIs for either $5 or $10 and mice are 
under $5.  I haven't checked the keyboard prices in a while which is 
why I'm uncertain on those.

Also, I forgot to mention, I'd also be looking for a couple of Ethernet
connections for them so I can connect them to my LAN.
Also at the Goodwill Computer Works store, their Mac Network Card bin 
has several LC PDS Ethernet cards for $5 each.  Some are AAUI and 
some are (or were last time I examined the selection) 10baseT.   If 
they only have AAUI, they also have some AAUI to 10BaseT transceivers 
but that adds to the cost.

Of course that doesn't help a lot if you're not in the Austin area.

You might also try Small Dog electronics.  In the past they have had 
a bunch of the Umax keyboards and mice either on their Garage Sale 
page or their Parts page for very low prices.  I don't know if they 
still have any.

From: Derek Morton [EMAIL PROTECTED]

When SCSI manager 4.3 is active you should indeed have access to 14
total devices.  Unfortunately since SCSI manager 4.3 is not active
until after the system loads, you really don't have access to all the
devices at boot time.
Ah, good point.   I wonder if SCSI ID conflicts (e.g. device ID 3 
used on both busses) would lock you up at boot time, even if the boot 
device does not have a corresponding ID'ed device on the other bus.

Another interesting possibility is that I believe I was told at one 
time that the JackHammer has a copy of SCSI Manager 4.3 in it's 
firmware.  But that memory is vague and unreliable.  If this is true, 
then having a JackHammer in the machine, might get SCSI Manager 4.3 
loaded before the OS is loaded.

 It is possible that once the OS loads it would locate the additional bus and
 detect the extra devices.  I am currently working on a truly souped up
 Q-950 (zoom-zoom)...
Sounds like fun!  I still wonder if ID conflicts between busses would 
stop the boot process before you could get SCSI Manager 4.3 loaded 
from the boot device.

Perhaps putting SCSI manager 4.3 in a custom system ROM...  H.
Do you know how to do that?   I presume that it's possible to add a 
resource like that to the ROM code without too much alteration, if 
one understands how the ROM code is organized.  If you or someone 
else can figure out how to put the code together I have a chip 
programmer...

OS 7.1 in ROM on Q660AV/840AV?

2003-09-28 Thread Jeff Walther
In my search for answers to my VRAM questions I downloaded the Apple 
document, Centris_660AV_Quadra_840AV.pdf   On page xxiii under the 
heading Software Overview it states,

The Macintosh Quadra 840AV and Macintosh Centris 660AV are supplied 
with essentially identical versions of the Macintosh System 7.1 
software, in ROM and on the internal hard disk.

I know that the Mac Classic has OS6.03 in ROM and one can boot from 
it.  Do the 660AV and 840AV have a similar arrangement with OS7.1 in 
ROM?   Or did Apple just mean that they ship a CD-ROM with the 
machine when they wrote in ROM?

SCSI Manager 4.3 and the Q900/950?

2003-09-28 Thread Jeff Walther
The Quadra 900 and 950 each have two hardware SCSI busses.   I.e., 
they each have two NCR 53C96 chips connected to electrically separate 
SCSI bus hardware.   However, the Apple hardware developer document 
Mac_Quadra_900.pdf states that The internal and external SCSI 
buses are logically connected but electrically separate.  Which I 
take to mean that if you use a SCSI ID on one bus, you cannot use 
that SCSI ID on the other bus.  This would result in a maximum of 7 
total possible SCSI devices spread between the two busses.

However, the Quadra 900 came out before SCSI Manager 4.3 was released 
and it was SCSI Manager 4.3 which added support for multiple SCSI 
busses.  This is discussed in Centris_660AV_Quadra_840AV.pdf.

So, if one has SCSI Manager 4.3 loaded (it's an extension as well as 
built into ROM in later machines) does the Quadra 900 support a full 
14 SCSI devices on its two SCSI busses (7 each).  Or is it still 
limited to seven total?

With SCSI Manager 4.3, the limitations are something like six physical SCSI
buses, with either 7 (narrow) or 15 (wide) devices on each, as appropriate for
the HBA.

You can easily get four buses on the Q950, and the WGS 95 does exactly that,
but not under MacOS.
That's good info to know, but it doesn't address my question, which 
was whether SCSI Manager affects the two built-in busses in the Q900. 
Put another way, does installing SCSI Manager 4.3 separate the two 
built-in busses logically, so that they have independent SCSI ID 
management.

According to the Apple Docs, when the Q900 was released, if you have 
a device on a SCSI ID on one built-in bus, you could not use that 
SCSI ID on the other built-in bus.SCSI Manager 4.3 has the 
potential to correct that, but does it in fact do so on the Q900?

From: vicki [EMAIL PROTECTED]

 Does the Q650/800 (Wombat) motherboard have the ability to address
 more than 1 MB of VRAM?  I know there aren't sockets available on the
 motherboard, but does anyone know if the chips have the ability to
 address more?   If so, has anyone hacked more VRAM into the Wombat
 motherboard?

I can answer this one .

 The 512k simms Yes they can be used  in the quads.
Thank you.  One answered.

The 512k simms are seen as 256k in the 800.
Thank you.  Two answered.

No the 800 mother board can not see more than 1mb even using the 512k
 simms.
On this final question, what I want to know is whether the components 
on the motherboard are able to address more than 1 MB of VRAM, even 
though there are only sockets for 1 MB present on the motherboard. 
So, in other words, if I wired up my own sockets, would there be 
address lines on the DFAB chip or the MemC chip to which two more 
banks of VRAM could be connected?

This may be the kind of question which only some Apple engineer 
locked in a vault somewhere can answer, but hackers manage to figure 
out some amazing things, so I figured I'd ask.

Consider the C610 ethernet fix and the C650 serial port fix that the 
clock chipping community came up with.   Given that, there might be 
someone who has hacked the VRAM, if the chips have the potential to 
address more.

The Q650/800 has 16M of address space allocated to VRAM, the same as 
the Q700 and Q900.   While that's more a function of ROM rather than 
the video circuitry, it is an indication that the hardware was built 
to address 2 MB of VRAM and then Apple limited it to 1 MB for some 
reason--probably to avoid competing with the Q700 and Q900.

I'm pretty sure there is one, but do not believe it is worth it. 
When the PPCs first came out it was marginally worth it.

Now days, the PPC upgrades are considered rare and command a bit of 
a premium on the used market.

On the other hand, you can probably buy a PowerMac 6100 (or variant, 
e.g. 6116) for less than the PPC upgrade.   I know that one of the 
guys on the swap list (I think he's still on the swap list) has a 
couple of new (old but still in the box) 6100s for sale.

The 6100 uses the same case as the 610 and has a PPC601 running at 66 
MHz.   There may have been an upgrade that ran at 100 MHz but the 
memory bus limitations would have made it not much faster than a 6100 
for most applications.

VRAM and the Q650/800

2003-09-27 Thread Jeff Walther
I have two questions.  First the mundane one.  Would someone please 
explain the taxonomy of VRAM SIMMs on the Mac?

I take it that there are 68 pin VRAM SIMMs and I think from reading 
the Developer notes and examining motherboards that the Centris/Q 
610/650/800 all use the same 256K SIMMs as the Q700 and Q900.  Which 
other machines use them?

Are these Quadra VRAM SIMMs the same as are used in the 12 MB HPV 
card on the 7100 and 8100?   If so, what happens if you install the 
512 KB VRAM SIMMs which are used on the 2  4 MB HPV card in a 
Quadra?  Are they seen as half their capacity?

Okay, now the tougher question.   I like the Q650 much more than the 
Q700 motherboard, except that the Q650 has a 1 MB VRAM capacity and 
the Q700 has a 2 MB VRAM capacity.   I am looking at installing a 
Q650 in a Q700 case.

Does the Q650/800 (Wombat) motherboard have the ability to address 
more than 1 MB of VRAM?  I know there aren't sockets available on the 
motherboard, but does anyone know if the chips have the ability to 
address more?   If so, has anyone hacked more VRAM into the Wombat 
motherboard?

Subject: Re: Q630 extra ram slot soldering.
I've just read http://www.lowendmac.com/quadra/630ram.shtml which
describes how a 630 can get an extra ram slot by soldering on a
72-pin ram slot into the empty pads on the motherboard. However,
that doesn't fit with my 630, that extra slot which is just solder
pads doesn't have enough pins! the other slot has all 72 pins.
Is this article mistaken, or are there other kinds of boards? Either
way what would this slot be for?
There seem to be two versions of Q630 motherboard. The one you have,
and another one with solder pads for a second 72-pin ram slot.
The smaller slot (with 64 pins) might be for a ROM simm.
I have examples of both on hand.  I don't know if either works, as 
they came in other piles of parts (I think I bought one for the 68040 
with FPU).  Anyway, the point is, there are indeed at least two 
versions of the board.   The one with the extra SIMM socket has a few 
other minor differences in component placement and such as well.

Re: 4GB HD in Quadra 605 / Performa 475

2003-09-18 Thread Jeff Walther

Subject: 4GB HD in Quadra 605 / Performa 475
Date: Thu, 18 Sep 2003 10:49:03 -0300
Hi,
a friend of mine gave me a seagate ST15150WC 4GB hard drive (specs
in http://www.seagate.com/support/disc/specs/scsi/st15150wc.html)
I have a Quadra 605 that ramdomly works (and I don't know what) but
it isn=B4t the problem now.
My question is: this HD will work in my mac?
Thanks!


The 15150 is a half-height (1.65) drive.   I think the Q605 requires 
a third height (1.1) drive or shorter.   However, I may be mistaken 
about that.   I'm sure someone here will chime in with the definitive 
answer.

Even if the Q605 can take a half-height drive, the 15150 runs very 
hot and very loud.  The slowness won't be a factor on the Q605 bus. 
I wouldn't recommend putting a hot 15150 in the Q605 and the noise 
will be unpleasant.

Finally, I think the 15150WC is a Wide Differential drive.   The wide 
part (68 pins vs. 50 pins for narrow) you could overcome with an 
adapter.   But there's no practical way to get a high voltage 
differential drive to work in the Q605.

So, no, that drive won't work in the Q605.   Even if it was an 
ST15150N (Narrow Fast SCSI) and would fit in the machine despite it's 
height, I would recommend against it because of the heat and noise.

Subject: Quadra 700?
Date: Tue, 22 Jul 2003 10:52:37 -500

I am looking for/considering the purchase of a Quadra 700.  I know 
this machine was
 used in the creation of Myst which increases its appeal a bit.  I 
even have a copy of
 StrataVision 3D (same s/w Cyan used) for it.  (StrataVision runs on 
a '030 but the
 speed is laughable).  What is the overall impression of this Mac in terms of
 performance/etc?
If you just particularly want a Q700 that's cool, but the Quadra or 
Centris 650 is a better machine and very similar.   The Q650 has one 
more NuBus slot than the Q700, an updated chipset which may improve 
performance some (anyone done comparisons?) and has a higher practice 
RAM capacity--which is to say that the firmware in the Q700 may 
support more than 68 MB, but the four 30 pin SIMM sockets limits it 
to 4 X 16 + 4 = 68 MB.  Whereas the Q650 has four 72 pin sockets 
which can go at least to 132/136 MB and possibly (does the Q650 use 
64 MB SIMMs?) 260/264.  Also, the Q/C 650 can be hacked up to 40 MHz 
without too much trouble (depending on how much trouble soldering is 
to you).

If you particularly like the IIcx/IIci/Q700 case, the Q/C650 board 
can be made to fit in one, but it makes a mess out of the rear panel. 
However, the power supplies are the same or at least compatible.

I also would like to give it some A/V capabilities.  What would be 
the best video-card
 for this Mac?  What would be the best add-on card for A/V (if the 
recommeneded
 card doesn't have A/V inputs?  (And if anyone has some of these 
cards, please make
 any offers to me off-list)
The NuBus Video Vision Studio is available for pretty reasonable 
prices these days.   I have one, but so far have only used it as a 
video card.Moving a VCR next to it to try out the video capture 
is turning out to be a huge mental barrier for me...   The VVS does 
not have sound functions--you use the Macs built in sound recording 
to record the audio portion of the A/V.

  Quaddies,
  I have  an XC68040RC33E chip pulled from a Q950 board if
  anybody wants it for $3 or equivalent  in swap. I could use a power supply
  (wallwart) for a US Robotics Sportster modem.
** end quote [R. A. Cantrell]

Timing, I've just asked on the UK list about sources for 040 chips to
upgrade my Performa 475s and LC 630.  I doubt the postage tot he UK
would be worth it though, and any PSUs I have would cost to much to post
out, not to mention being UK ones - and come to think of it, required
for the modems if I ever need them again.


I agree that wall wart postage would be prohibitive, but I believe 
that the 68040 could be shipped to the UK in an affordable manner. 
There'll be a small risk, but not much.

I suggest pushing the pins of the 68040 into a stiff piece of foam 
(that black anti-static foam is nice, but styrofoam will do in a 
pinch) not much thicker than the pins are long.   This will give you 
a 1.7 X 1.7 X ~ 3/8 thick package to ship.  Perhaps tape the foam 
to the chip to inhibit sliding.  Put it in an anti-static bag.  Then 
stick it in a padded mailer (4 X 7 should do) and postage will be 
about $1.60 to the UK via Air Letter Post.  I think it will weigh 
under 2 ounces.  That size padded mailer is about $1 at the post 
office or drug store, or $.40 if bought in a box of 25.   The only 
other thing needed is a #2976 customs form available at the post 
office.

For extra security a layer of the small bubble wrap could be wrapped 
around the chip.

Re: Frustrated with Q repeats, Was: Read the FAQs...

From: E McCann [EMAIL PROTECTED]
Subject: Re: Read the FAQs and archives


Well, not having seen your name on here (under *this* alias) before, I can
only assume you're expecting a negative response.

I think if Grin With Me had stopped two sentences short of the end 
of his second paragraph he would have done better.  I was with him up 
to that point.

All I'm going to say is:
1. Yeah, I agree about the lists. I also agree about checking the FAQ,
though if you just see the list, join, and ask a question, you may not know
about it.

So, instead of *just* saying Read the FAQ (I'll bet there are still a
good number of people who join that not only don't know about the FAQ, but
couldn't tell you what a FAQ was) how about modifying the reply:

That's actually in the FAQ, which is at http://macfaq.org. Go to the 
section, there are some links / info / pictures / free toasters with
signup. If you need help with some of what it says, feel free to ask.

As far as the TILs, it depends who has what links - some still point to the
old location, some to the new, some who knows where.

I add my voice to the chorus that Read the FAQ does not a very 
helpful community make.   Most of the folks who are going to ask the 
oft-seen questions are also likely to be somewhat disoriented on the 
topic and find it rather difficult to make the leap to the FAQ.   It 
all seems terribly simple to the experienced user, and I know it's 
tough to understand, but when one isn't familiar with a topic, the 
simplest information can be bewildering.   A simple example is that a 
FAQ may not phrase the same quesiton in the same way as a new user 
who doesn't understand the terminology, etc.

I would like to suggest that if one is frustrated at seeing the same 
question asked by newcomers or even oldsters, rather than lashing out 
at the inquirer, perhaps the frustrated folks could simply refrain 
from responding, and let happier people field the easy questions.

I am very active on the SuperMacs list.   And I sometimes find myself 
frustrated with repeats of questions I've answered many times over 
the years.   Now this is silly, because the asking of that question 
doesn't cost me anything except a moment reading an email.

A bit of introspection and I realized that the frustration arises 
from a self-imposed feeling that I have some kind of duty to answer 
questions on SuperMacs.   So there's this feeling of duty to answer, 
then someone asks a question I'm really tired of answering, and I 
don't want to answer it, but I feel like a should, and voila: 
frustration.I found a really simple solution to this that didn't 
involve any rude comments.I just don't answer those questions 
that I won't enjoy answering.   And you know what?  Someone else 
always manages to field those questions.

So my experience may not be the same as others, but there it is in 
the event that some might find it helpful.

Jeff Walther

P.S.  Anyone know of any use for a Q630 MB sans CPU?   I know it 
isn't worth anything to sell, but I'm reluctant to throw it away--all 
those custom Apple chips on board.

NeXT keyboards on Macs?

From: Robert J. Johansen [EMAIL PROTECTED]
Subject: NeXT keyboards on Macs? (FAST answer needed!)

Dear Quadraphiles:

I'm hoping for a FAST answer to this question, so if you could reply to me
directly as well as the list (I'm in Digest mode) that would be great!

Are NeXT keyboards compatible with, or can the y in some way be made
compatible with Macs, particularly Quadra-era 68K or 1st generation PPC Macs?

Some NeXT keyboards are ADB and some are not.  I have a couple of 
NeXT keyboards and the model number on them is N8001.  These are ADB. 
They are an extended keyboard (with keypad) but lack all function 
keys (F1 - F15).   This makes them narrower (less deep) than other 
keyboards.   The keys function properly as you would expect.  The 
command key is below the space bar as a second bar, which takes a 
little getting used to, but I find it nice, as so much ported PC 
stuff requires a CMD-click to substitute for a right-click and it's 
easy to just let the thumb do the double duty of space bar and CMD. 
The thumb is underutilized in a traditional keyboard.

Message-ID: [EMAIL PROTECTED]


As I noted in my prior message, I recently purchased a Quadra 950 and I want
to max out the RAM.

Does anyone know of a good, cheap source for high-capacity 30-pin SIMMs?

Here's some of the places I've checked:

OWC:
16MB - $12

18004Memory.com
4MB  - $5.50
16MB - $10


These are great prices, but to max it out with 16MB SIMMs it will cost $160
before shipping. Anything I can to do reduce this is in my best interest!

There was an Ebay seller who had them at $15 for a set of four.  That 
is, 64 MB total for $15.  I think his ID was sunguk.   I haven't 
bought from him myself, but I think soemone on the Compact Macs list 
said he had and that the fellow was okay, unless there was  a problem 
with the item and then he was kind of unfriendly.

The problem is that the NEC drive is not supported by any version of

might be too tall for some applications.

If you're going to be learning something from scratch, you might be best off
downloading MacPerl and using that.  Perl was built from the ground up as a
text-handling language and from what little experience I have with it (writing
the serial number decoder for the early Macs for the FAQ), I'd say it's
*perfect* for what you want to do.

Perl is perfect for most things.  After all, it is the Pathologically 
Eclectic Rubbish Lister.  :-)

... I'm not sure what the XC or B means yet, still learning. 

RC is the package type: ceramic, pin-through hole, in this case.

B is the step, the particular revision of the masks used to make the chip.

XC should read MC, meaning Motorola, not XC, and the LC will be
absent on a full function chip.

Motorola often substitutes an 'X' for the 'M' in early runs of their 
chips.  I forget the exact explanation of the meaning, but it's 
something like, this was an experimental run, and they're good enough 
to sell, but it's not full final production.   It probably affects 
the price and/or the contract between Motorola and the buyer somehow, 
but doesn't seem to have much impact on the end user.

Such a full function chip would read: MC68040RC33B, and this would decode
as follows:

You will also find full function 68040s with the part number 
XC68040RC40 for example.

I've also seen quite a few PPC processors from Motorola with XPC 
instead of MPC.  The Umax 233 MHz PPC604e card, e.g., has XPC604E 
chips on them--at least one batch of them did.

The totally kewl ones are the model which have a built-in hub.

I read that as The totally lewd ones at first and was very puzzled. 
Anyway, do you mean the Farallon Etherwave adapters?  Those seem to 
turn up in the Goodwill bins pretty often.  I think they get about $5 
for them, though it might be $10.

I have an adaptor and will scan it later, as the Christmas duties are
calling. Let me know if anyone wishes to have a scan of this device.
