It's not an issue of a loose chip or connector as I had removed the board from the case to work on it at the bench, and reseated them all there. The voltages are all measured within spec. The normal ROMS also display a series of colors on the screen, in no particular order. DiagRom, as it goes through addresslines during memory check, will change the screen colors red, blue, green, yellow, etc. I will play around with this a bit more, as I believe all the "main parts" (customs, CPU card) and RAM are good. Failing that, I'll do a transfer over to a ReAmiga board. Last time I did one was 2018 after building up one of those Alice+ boards I bought from Hese on Amibay....not looking forward to doing that again
