Finally got the board to boot. It originally had an unknown upgrade processor (QFP on adapter with glued on heatsink and identifying labels removed by previous owner). The jumpers were not set for any known 486 clone. I replaced it with a working 486DX4-100 &EW. It still wouldn't boot.
Today I looked at all the jumpers, and found one that doesn't have an identifying mark on the board and is not mentioned in the partial manual I found or on any website I found. I removed that, and it booted! I feel a right fool, I'm guessing I had been trying to boot with the Clear CMOS jumper closed for the last few weeks 😀
Going to give up for the day as soon as I test it with the Cyrix chip. Tomorrow I will install Windows 95 to make sure it is stable.

Constantly being worked on. Feel free to message me with any corrections or details of cards you would like me to research and add.
