ACSI is close--there are some differences from SCSI.  I still have a
board I built back in the day to bridge the SCSI-ACSI difference.  I
used it with an OMTI  ST506-RLL-to-SCSI converter.   I probably still
even have my driver code somewhere.

The connectors are a bit unusual, though--I think they're something like
a DB19.

However, there are modern versions of the ACSI adapters:

I have a load of all of those...  2901Cs the faster ones. The 2901 tends
to force
the flavor of the hardware and instructions toward microcoded machine.

If your doing your own design an interesting flavor is a TTA, Transport
Trigged Architecture
sometimes called a OIS (one instruction machine).  For that the machine
has one instruction
I did a Move machine and the whole word is source, destination and
options like jump if zero.
Tends to be very unique, can be fast and fairly simple since the
instruction cycle is fetch, do,
and repeat.  That can also be used as a microcode engine for a more
conventional machine.

Atari ST SCSI hard drive question

[Win Heagy via cctalk]

I have an Atari 1040ST that I picked up some time back.  It is very clean
and for the most part appears to work.  It has what appears to be some kind
of generic SCSI hard drive (no markings except a serial number on the back)
as well as a DMA/SCSI adapter.  The computer will boot to GEM/TOS with or
without a floppy, but I can't seem to get the HD to do much.  The HD powers
up and spins/clicks like you'd expect, but after that, I get nothing on the
desktop.  I tried different SCSI device number settings as well as moving
the SCSI plug to each of the two plugs on the drive.  It did not have a
SCSI terminator with it, but I picked one up...made no difference.

I know very little about STs, so am learning as I go.  I'm guessing that
maybe there should be a driver for the HD?  The machine came with software,
but I don't see anything that looks like an HD driver disk.  It has two
slightly different language disks and will boot each of them successfully,
but the HD does not show up.  Is anyone familiar with this particular drive
and can possibly point me in the right direction?

https://imgur.com/a/pxMxl

The adapter on top is a male to female adapter.  Not sure what that was
for.  The SCSI terminator is plugged in the back below the DMA/SCSI adapter.

it had sat idle in the storage room for ten years and I needed the space.
That is shameful.

Alphaserver 4100 - Give my Monster Life!!!!

[Richard Loken via cctalk]

My monster lives!

After being brought home in a dozen parts, cleaned with Windex and an air
compressor, and reassembled, my Alphaserver 4100 is once again up and
running OpenVMS.  There were a couple minor snags while I went up to the
attic to find a CPU fan, move a ton of stuff to find an electrical outlet,
and reseated the memory modules but all that is behind me now.

It is using lots of electricity and making lots of noise while displaying
a Motif session in a 19" liquid crystal monitor without a stand...

What could be better than this?

In addition, a tool like the Altera Signal probe allows you to bring any
signal you want to a pin you select so you can use an oscilloscope or
logic analizer to look at it if that is how you are more comfortable
debugging hardware. Another option is to include a whole logic analyzer
inside your design, like the Xilinx ChipScope or Altera SignalTap II.
That talks to software running on your PC and has all the functionality
of a real logic analyzer.

I have not used these tools myself but instead did the equivalent the
hard way: I patched the VHDL code to bring the signal I wanted to look
at to the pin I was probing with my oscilloscope. That was a bit awkward
when the signal was several levels down in the design.

My point is that though Al is right that it is better to debug with a
simulator, those of us who prefer to look at the real thing lose nothing
with FPGAs. In fact, given how hard it can be to attatch 60 little
probes to pins which are very close together we actually gain something.

By the way, in my scheme I actually had a case where it was hard to
debug because the FPGA worked one way when I touched it with the
oscilloscope probe and did something different when I didn't.

Support should be live 24/7.

The software needs to function under DOS, Windoze, Linux, Mac, Android.
The software needs to provide raw flux transitions, along with 
firmware to be compatible and work with CatWeasel, Kryoflux, Option Board 
software.
It should have imaging software, both flux transition and IMD 
compatability.

It needs to provide disk, track, sector data.
It needs to include complete emulation of WD-179x, and NEC-765 
controllers.  The NEC emulation should provide optional going blind after 
index, as well as multiple variations of how it handles 128 byte sectore.

WD-179x support should also add WD-1771 address mark support (TRS80)
It should have windows drivers that permit it to be the floppy system.


It should be able to duplicate ANY disk, including all copy-protection 
schemes. (supply a paper-clip for making scratch for pro-lock)


It should have "Installable File System" support sufficient to be able to 
mount 2500 different floppy disk formats.
Sufficient buffer to read data from disk in one format, reformat the disk 
in another format, and write the data back to it.
Its software should identify and report the disk format of the disk in the 
drive.


Optional scan and repair of file-system and sector errors, including 
"refresh format" (read data from track, reformat track, write data back 
out)

Multi-language spell-chequer?
Alignment exerciser, plus software for DDD in ROM.

Built-in SD slot for storing content of disks.

support for disk changer and high speed copying


Interface should include USB (micro-USB for Android), RS232, 
Centronics-style parallel, 20-mA, . . .


Should it include emulation and drive support for ST412/506? ESDI? SCSI?

But, we're probably not including some essential capability.
Whatever features it has, SOMEBODY will say that it is INSANE to have 
bothered with some of those features, but not to have included some other 
feature that they want.

I am not to sure about that.
If a schematic has a bug you can use a logic probe to find the error.
With typo in VHDL you have hard problem finding that single gate
error.

The trick is to get it close enough to correct, given the documentation lapses. 
 The PDP-11 is better off than many other machines (VAX and Alpha are better 
still) because it has an architecture manual, but even that is not 100% 
complete.

http://pdp2011.sytse.net/wordpress/pdp-11/ is a nice example of an FPGA PDP-11 
(actually, the whole family -- conditional compile the model you want).  It 
seems pretty accurate; the fact that it runs RSTS is a good sign since that 
tends to be about as picky as any PDP-11 software you'll find.

>

No, but I remember CD4000 series logic: Vdd anywhere between 3 and 18 volts -- 
crank up the voltage if you want it to go faster ("less slow").

   - I drive a coupe so I can only fit so much - a 75lb chassis is unlikely

A few more things

A couple Nova core memory boards
lots of random connectors/cables/SMT parts etc


The Dectalk is still here, for people that expressed an interest, I really

Mine are for specific-purpose applications, so they're not likely to be
of use to anyone else.  Note that I'm not interested in archiving disks,
but rather getting at their content and saving that.

But golly, it isn't that difficult--most MCUs have several timers, and a
"capture" facility so reading should be easy.  Writing is again, mostly
feeding a PWM output to the drive.  The floppy interface itself is very
much brain-dead.

This isn't news--the HxC emulator basically does the work and runs on an
STM32F1 platform--which is weak tea compared to the ARM CPUs currently
available.

My .02 cents.

The minimum legit voltage swing for RS-232 is supposed to be plus and minus
5 volts and the
maximum allowed voltage swing is plus and minus 25 volts.  The problems
occur when gear didn't
bother to do the negative swing to minus 5 volts.  Plus and Minus 10 volts
is more than adequate.

The ribbon on my 43 is a reinking type.  The ribbon loop is maybe 18
inches?  I have a new in bag
ribbon which I am sure is also dried out.  I used a drop of thin oil on the
reinking roller the last time
I messed with it and that seemed to work.  You probably want to use
something that will lubricate
because the pins on the dot matrix print heads do need that to keep them
from rusting and wearing
out.

The "stutter" you mention is normal.  The printer electronics buffers a few
characters during the slow
carriage return and prints slightly faster than 30cps so when a new line is
started it goes at full speed
until the buffer is empty at which point it goes into the stutter mode.
This eliminated the need to send
nulls after a carriage return that was necessary on the earlier purely
mechanical printers.

I think the collection has limited value at best and likely only a few
select pieces.

However,  To make the point to someone I showed them what they put on
the net and then
compiled it into a picture of who, what, and even when.  They
immediately stopped posting
all their daily activities and much of the personal stuff.

Great to hear of the progress.

From what I remember and from what the Wikipedia article mentions, +- 10 volt 
is certainly fine and RS232-compliant.  I remember PCs that used TTL levels (0 
and +5 or so) which clearly is not valid (not to mention that TTL level ICs are 
likely to fry when confronted with valid RS232 inputs such as -15 volts).

Your null modem experience makes sense.  There are a bunch of different signals 
whose meaning is often not clear, and older equipment is more likely to want 
all of them.  CTS is the main one, but while you might argue that DCD (carrier 
detect) shouldn't be required, it isn't too surprising that a terminal might 
look for it.

Equipment). TXD is therefore the input (!) of a DCE (Data Communication 
Equipment aka modem).
PC RS-232 ports send on TXD because they consider themselves to be a 
terminal. And a teletype IS actually a terminal. So you would need to at 
least cross wires 2 and 3 (RXD/TXD) using a Null modem. If you want 
hardware handshake, the same applies to DTR and CTS.


Good luck :-)

I'm surprised to see a swedish keyboard there :)

What is a PCM-12 ?

And I think that Datability VCP-1000 can do LAT to TCP/IP  translation.

I think so. It would at least be nice to see a picture.

If it's smallish I might even pay postage for it :D

Sigh. Looks like default permissions weren't "public", but Flickr/Yahoo
is also suggesting this heretofore alien URL format:

https://www.flickr.com/gp/smj_crash/4bgzj2


Seems to work, though it looks like it's just a redirect to a more
common format...

YMMV,

It seems that you are suggesting people are worried about their collections
being attractive to thieves. Well, that may be true for the lucky few, but
for me it is simply about coordinates for identity theft and other kinds of
criminality.
