I've always wanted to build an original P5 based 1993 Pentium system. I know it is not the most practical retro computer. But I want to have some fun with the FDIV bug and refresh some early 90's games.
After some effort, I finally sourced a suitable board. I got it cheaply off eBay and it is new part (new old stock). However, it is an OEM board. Looks like it is from a DELL computer.
1) Can you help me to identify the board?
2) Any ideas about PSU pinout? Could a regular ATX PSU be rewired/passively converted to work with this?
3) Do you know if there is any chance to find a riser card for this board? I found some DELL riser cards on eBay. However, I am not sure if there is a chance that a random DELL riser card that fits in the slot would just work. Some of the riser cards have extra chips on them, different slot configurations, etc.. Any idea what to look for? I would appreciate at least one ISA slot for a sound card as the VGA is included. I believe the CL-GD5430 isn't too shabby VGA for an early Pentium system.
4) Any thoughts about CPU heatsink? Do socket 7 heatsinks generally fit on Socket 4 boards? P5 CPU's are slightly bigger than P5C AFAIK Finding a dedicated socket 4 heatsink seems impossible.
