Playing w/ the Idea of a 90's Era PC


Recommended Posts

OK, so I got my 486. Tore into it. It has a decent Crystal sound card. ISA slots all around. No PCI. Wondering if I can buy a riser board with PCI on it and have it work, even though the riser is an ISA piece. I think so. I've found a few on eBay. My CPU is NOT the stocker. The stock CPU was a Intel 486SX25. This has a later Intel Overdrive in it. A 63MHz with intergrated heatsink and fan. Kinda neat how that is put together. Been a million years since I even looked at this machine. I got it used, so yeah. Lol. 100W PSU, nothing super there. 210Mb hard disk. Lol. OG to the machine.

 

Problem. CMOS battery leaked, and now it doesn't POST. When I last had it out, it would post, boot to DOS, or Win 3.11 whichever I chose to operate under. Worried that despite having some goodies under the hood, that I need to get a new board. Could someone with a bit more raw knowledge weigh in on this? Pics coming.

I doubt you can add PCI to a motherboard that doesn't have it. Does it even have Vesa Local Bus?

Nah. It's pretty archaic. It doesn't POST now. CMOS battery leaked, ate a trace. Got a Compaq Presario 2240 with an AMD MMX200, 32Mb RAM, 2Mb S3 Trio graphics, jammed my 4Mb Voodoo accelerator card in there, 6Gb HDD. Not the worst rig for DOS gaming. The onboard audio seems compatible with Soundblaster standards... But I'll hang on to the Crystal if I run across something that panics.
