THANK YOU!!!!
I have a pile (well, 3) of 4MB parity SIMMS from a Gateway 2000 in my
basement.

THey are real and used to control signs and a few other things. Not
likely in the near future from what I've heard.

Not sure if this got thru. If it repeats my apologies.
A while back there was a thread re an Archive board ID but I've been unable to
find it in my archives. It seemed at the time similiar to a card I have.
It's an 8 bit card with a 25 pin F port and a 50 pin internal; it's got an FCC
ID # EAX6GP-SC400S which I haven't checked yet since most of the time
they're useless. Someone had written 102 A in marker pen.The most important
chip is one labelled Archive PT and at the bottom 8517A. It has an E-Prom
m5l2764k , another 64 pin chip has 4 numbers , the top one is R6511AQ and the
bottom one is 8439 (always had trouble identifying chips based on labelling).
It has IRQ stencilled jumpers 2-7 and 5 is jumpered. It has DRQ (DMA ?) 1,2,3
, DACK 1,2,-3 with 1 jumpered on 1 and 3(1), another set of 7 jumpers labelled
A3-A9. There are 5 LEDs labelled DS1-DS9. There's a couple of other jumpers and
the rest is mostly low powered Schotskys.
Anyone with any idea on what this is ?

Found on Usenet. If anyone of our UK readers is interested, I'd suggest
getting hold of the person before they turn it into a rabbit hutch. ;-)

Spam is bad. Spam is theft of service. Spam wastes resources. Don't spam, period.
I am a WASHINGTON STATE resident. Spam charged $500.00 per incident per Chapter 19 RCW.
I don't know if this is worthy of being a Classic Computer, yet (it's 8 yrs
old), but here it goes:
I have a PS/2 L40 sx laptop. It has 2MB onboard RAM, and a 60 MB HD. I
was wondering if anyone had any expansion RAM, or knew where I could get
some for a low price. It has "planar sockets". They look like standard
72-pin SIMM sockets, but Non-parity won't work, parity won't work, and not
even PS/2 RAM works in it. I guess it needs a special type of RAM that was
made by IBM especially for this computer.
ANY information is appreciated!!!

I tried scraping, I scraped so much that I scraped throuh to the
white part of the PCB. It still conducts. I can't see any solder
bridge, but plugging it in causes smoke to emanate from the cable.
