[Coco] Coco Digest, Vol 131, Issue 34

[Andrew]

Well - I actually have all of that covered; I have one working 386 
motherboard (an AMD DX40), several 486 motherboards (including my first 
486 PC), and more than a few old Pentium 1 mobos (not to mention 3 or so 
AMD 586/133 boards - the best souped-up 486 there ever was!).

So - an ISA board should work ok (in an EISA slot - IIRC, you can use an 
ISA card in one), and speed shouldn't be an issue (unless even my 386 
would be too fast - even out of "turbo" mode). I've got a ton of 
"slowdown" software for DOS as well, if that would help any in a pinch.

I just couldn't pass this box up, for a dollar. Heck, the four ZIF 
sockets are worth that much.
