less than a top of the line Logitech and the iSight will work much better. 
However IMO in your G4 533 the performance on Skype or iChat will be a

use with a web cam is a Dual 1.25 MDD. But that's just me.

Thermal Compound Question

2010-11-03 Thread Jonas Ulrich
Hi all, quick question here, I'm looking to buy some thermal compound, and
am wondering if all is the same? Or if there is a better brand I should buy.
I'm just looking on ebay, and the stuff is cheap. Just wondering, is there
varying qualities? Or is it all the same stuff.

Just to be clear, I'm looking for the grey stuff you put on a processor to
help transfer heat to the heat sink.

Thanks!

 I've never liked Western Digital's stuff, I had a round of lemons from

Every drive manufacturer sells a round of lemons at some point.

Maxtor made some 120 MB (that's MB, not GB) drives that failed just
out of their one year warranty fifteen years ago.   We had forty of
them at my office at the time.

IBM had the Death stars (Deskstar).

Seagates 1.5 TB drives may qualify, and check out the feedback on
their low-end 2 GB drive at Newegg.  Of course, one doesn't know if
those hundreds of failures are out of 2000 or 200,000 sold

I'm sure Hitachi has had a lemon at some point, but I've only ever had
one or two of their drives, so I missed it.

I tend to stick with Seagate these days.  Their five year warranty
won't save my data, but it means they have more motivation to put
effort into quality control than a company offering a three year
warranty.

Well Joanas I just happen to be applying some right now. There seem  
to be many brands and all claim to be the do all end all product I  
have 3 different ones and I can't say I've noticed a real difference.  
Some claim to have silver dust which sounds good and expensive and  
also you would think a very good thermal conductor and then I have a  
tube of a diamond dust product that costs a couple of bucks more, I  
really don't understand diamond being a thermal conductor but maybe  
so, and then I have a tube of a white paste that a Apple Depot in  
Texas uses. They all seem to do the job if applied properly, be real  
clean and just a very thin coat is all that's needed. Too much will  
defeat the purpose:-)

They all do the same thing. Arctic Silver has a good reputation but I 
cannot tell you if it is as good as it's rep or not.


When I buy thermal paste I avoid the very cheapest ones and look for a 
name that I recognize. I have used Arctic Silver and Antec Formula 5 and 
both have worked fine (I can't give a thermal comparison because the 
only temp sensor on my iMac is for the HDD).

Sophos was throwing false positives like mad on Java last month; we have the

Running the .exe on your mac would have done absolutely nothing. All you would

Diamond is an excellent conductor of heat, a property which is

diamonds from real ones.


The testing device measures the subject gem's properties and returns  
a GO or NO-GO indication.


Manufactured diamonds can be detected, too, by their difference in  
fluorescence from natural diamonds.


Anyway, the thermal paste which includes diamonds, either natural or

Mismatched SCSI connectors... (G4 Sawtooth)

2010-11-03 Thread A.M. McCullough
Howdy, all...

I've been cleaning out some old computer gear and came across my old UMAX
1200S Astra flatbed scanner (which I originally bought for a PC) and thought
to myself, hm, why not see if this thing will work with my Sawtooth. Hm
again - the Astra's cable is a DB25 male and the Mac has a SCSI card with an
HD50 female connector. I do not know if this card works, I don't have
anything to hook to it. Does anyone know anything about these cards - what
information do I need to dig up for it to see if it would talk to the
scanner?

I cannot find the original SCSI card that came with the scanner - that
appears to be lost to history at this point. Do you think an adapter to the
existing SCSI card might work, or should I try to locate a card like the one
shown here:
http://www.amazon.com/Adaptec-2906-SCSI-Windows-Support/dp/B5111H ?
That's a ton of money to spend on an ancient scanner that hasn't been turned
on in over a decade.

Any thoughts or ideas welcome :)

Thanks,
Annie M

Well that's good to know because Fry's keeps the diamond product in  
stock and I'm getting low on it so no confusion next time to buy.


I have noticed that Apple used a thick paste on the G4 PowerBooks, I  
assume this is because the possible flexing and ambient temperature  
changes of the components could break the thermal contact, therefore  
I use just a touch more on them.

I believe its probably a PC only card. My UMAX Astra 2400S came with a  
PC SCSI card and it did not work in my PCI Mac.


I'm using another SCSI PCI card and it works fine ... its an  
ATTOExpressPCIPro type card. I got an external adapter from  
mcpricebreakers (mcpb,com) that fits in the opening in the back,  
usually used by another PCI card or by a dummy filler bar.


Good luck.

As you can get a NEW scan-print-copy machine for about the same price  
as the card, it seems
a waste. There are adapters to connect the 25 pin SCSI port on the  
scanner to the connector

in your Mac. Or cables with different ends to do the same thing.

I had no luck trying to get my Astra 1200S connected to my AGP  
graphics SCSI card (might be
the same one you have). Had the connectors but the computer could not  
see the scanner.
Found an Epson with Firewire that is a better scanner and faster than  
SCSI so retired the 1200S.

The cards which have high-density 50-pin connectors (also known as a

Yep, sounds like an adapter is the way to go. I don't mind throwing ten
bucks at it for the cost of an adapter plus shipping just to see if it
works, since I have no idea if the card that's in the computer right now is
at all functional. I'm pretty new to Macs overall and SCSI is an older
technology that doesn't really exist in the PC world any more, so I wasn't
sure if I needed a specific type of card or speed to talk to the old
machine. Anything over ten bucks - well, now, let's see who recycles
scanners ;)

That explains why the Mac has that particular card in it :) I don't have the
original card that came with the scanner at all, but now that I've been
trying to remember about it, I do believe it was a PC only card anyway. So
that brings me back to scrounging an adapter to see if the old beast (it's a

has any life left in it :)

Re: Mismatched SCSI connectors... (G4 Sawtooth)

2010-11-03 Thread Doug McNutt
There is something that doesn't make a lot of sense here.

I don't think there ever was a peecee that used a DB25 connector for SCSI. Only 
Apple ever did that and they shorted a bunch of grounds together while 
violating SCSI rules of engagement.

Was that scanner really a peecee parallel-port device?

What is an HD50 connector?  Do you mean a two row connector for a circuit board 
as Apple used internally with a flat cable? Or is it a 50 bin blue ribbon job 
from Amphenol? It's possible to solder from a DB25 to a DB-style 50 pin 
connector but it's a real pain to do a high density 50 pin job.

The Iomega folks used 25 pin SCSI connectors on its Zip drives. Their pinout 
was the same as Apple's DB25's. Those cables ought to be all over the place. I 
might even have one.

The G4 Sawtooth used ATA 40 pin connections internally. There are PCI cards for 
SCSI one of which which I assume you have installed. Did Astra supply something 
like that with a DB25? I'd be surprised if it did for use with a peecee.

Re: Mismatched SCSI connectors... (G4 Sawtooth)

2010-11-03 Thread A.M. McCullough
Ummm ... yep, I bought the Astra over fifteen years ago for a PC. Yes, it
came with a SCSI card and cable to install in the PC. I have no idea who the
manufacturer of the scanner's card was, but it worked well back then. No, I
do not have THAT card any more, not that it apparently would make any
difference if I had since evidently it was only for use in the PC. Yes, the
G4 Sawtooth has a SCSI card in it already - I bought the G4 used a couple
years ago and it came with the machine, I've never had anything to plug into
it to see if the card is even functional. It is NOT a ribbon cable. It is an
actual card with a connector that looks like this:
http://www.ramelectronics.net/scsi_connectors.ep, eighth photo down, the
HD50 Female connector.
I have a USB zip drive so that ain't much of a help (grin) and besides, I
don't need the CABLE. That part I have. What I need is something to connect
it to the Mac's card. And nope, I ain't soldering anything - that's WAY too
much work to put into this old scanner :-)

So I'm off to post in LEMswap and see if I can snag a cheapo adapter for
under $10 - I'm willing to throw that at it and see what happens :)

Both were codified in the SCSI-2 standard.

The external connector is a SCSI-2 HD50 type, and the internal
