>From the sounds of it I'd say we need to know exact hardware to continue. a 286 'made into a 486' could mean anything from a sane upgrade (swapping out the motherboard) to an insane upgrade (like the intel inboard 386 I have for one of my IBM 5150 PC's which uses the original motherboard and is incompatible with darn near everything). If you are unable to get us a model number or brand of the motherboard, see if you can snap a pic of the motherboard. Depending on the era of 486 if it was indeed a motherboard swap, there's a slim possibility it could have pci slots. If you can find out nothing else, find out if it's using 72pin or 30pin memory. The kernel you end up using will be highly memory dependent..<br>

</div>Maybe. I believe there used to be ISA-based USB cards out there. Best<br>
place to find such a beast would be CompRenew.<br>

Absolutely not. A SATA controller attached via ISA would be an amazing<br>
thing indeed.<br>
<br>
Although...There *may* be PCI controller cards out there that attached<br>
to an ISA bus. (Wouldn't that be strange...) Still, your I/O<br>
throughput would absolutely suck. You'd be better off using an<br>
IDE->SATA adapter.<br>

</div>No. You'd need a network card and the appropriate packet driver for<br>
it. For Linux, an old 3Com 3c509 would be just perfect.<br>
<br>
Really, though, it souds like you just want to be able to drive these<br>
I/O boards and relay controllers. The Radio Shack in Woodland Mall has<br>
USB versions of these for only $50. That's going to be a far, far<br>
smaller headache.<br>
