I've meant to fix this Amiga 500 for a few years now. I had originally stopped working on it when we moved into the house and it's only been lately that I've been able to return to it.
I originally tried to update kickstart 3.1 with a board to make this version of the motherboard work correctly with this kickstart ROM.I originally tried to update Kickstart 3.1 with a board to make this motherboard version work correctly with this Kickstart ROM. This caused a black screen during boot. I removed the 3.1 Rom and returned to the 1.2 Rom, which still didn't work/stopped on a yellow screen. Somehow I zapped the machine and now it all is working correctly. It's very strange, but it's all good. I tested the floppy drive and it's working fine. The last hurdle is getting the keyboard working correctly & building out a cable for analog RGB.
