Ok, i know i see flames coming on this one but i have to ask, hell, it's
for my mother.
Does anyone have a spare AT pentium board with docs? Hers was for a
386/486/P90 when the P90's were new and it died the horrible death of blown
circuits. She really loved the machine and i'm looking for a way to give it
back to her working once again. No Sridhar, put the hammer down, hehe.
Anyone have any ideas, it had 2 VESA Local Bus slots, 3 ISA and 2 PCI? I'm
willing to pay reasonably for it, even more if it actually has a chip on
it. I have an original Zoom 14.4 VFX14.4V Serial modem with working power
block and DB25M/F Serial cable (components dated 1991 and 1993 - probably
cuz this is the voice/fax model). Was the like the one used in that stupid
movie "Hackers" and is only missing the black semi-see-through faceplate.
I'd toss that up for grabs with money for anyone who can help me out. And
yes, still working on figuring out all of the damned SOL stuff. Chandra, if
Newburgh (45 mins from Danbury) isn't too far from Boston, let me know, the
SOL's still here.

WAY too long to give away all my old '386's, and the only one I kept was one
that uses a '287 coprocessor, just for interest.

Based on OPTI chipset and very poor quality, works w/ 1 72pin simm
but severely penalizes performance. Pair up of memory simms and
performance improves but not as fast as true pentium chipsets.
Some of them can be set up either 486 or pentium.
If you're going to use it as a server, e.g. under Netware, you don't need
a hot
processor. The disk I/O proceeds via DMA at the rate at which the drives can
go, and the network I/O does too. The CPU is idle much of the time, since it
really only manages the transfers and handles directories. With one or two
people, 4 at the most, even a '386SX-16 would be plenty.

AST uses still-born CUPID slot. Usually grouped of 3 slots. I have
seen 386dx, 486 CPUID cards but they don't exhange easily on
different AST CUPID motherboard. I know because I have done that
before. AST did make pentium CPUID cards also.
