I finished building my 8800c. My RAM card is an old Compupro RAM 17 from the 80s. It used to be installed in my old North Star Horizon.
When I fire up the 8800c the data bus lights are all on, which doesn't change no matter what I do, and the address and status lights are flaky. Same thing if I take the RAM card out. I suspect when the old Horizon died it took out my RAM card as well. I've ordered a new chip set for it and will hope for the best.
I'd also hoped to use my Morrow Designs DJDMA disk controller from the Horizon. I'll be that's fried too.
Sometimes getting these things working is like death by a thousand paper cuts
But it's fun ;-)
