  1. Hello. I have a 486 motherboard with 1 ISA, 6 EISA and 2 VL-Bus slots. Includes 8 SIMM slots. Only has AT Keyboard connector. No FDD/HDD controllers or anything else built-in. It has an ALI M1429 chip with AMIBIOS 486sx ISA Bios and JETkey v5 keyboard bios. The code on the board says SXCPCB870A1 but I cannot find info on it anywhere. The board layout looks very similar to the Shuttle HOT-409 board but is not exactly the same.

  6. Okay, I will try this again. I have a socket 478 Supermicro, either a P4SGA or a P4SGC. They no longer have manuals for it. Can they be found anywhere? It still works great, but is finicky enough to require a manual. (I need more RAM, and it is picky)
