Well, I have to say that was part of the problem, the crystal was partly out of its socket but there's even better.
I don't know if its in this thread or another that I read that A3000 computers have a tendency to have problems with their VGA ports.
Just for the sake of trying everything, I plugged in my old 1080 to the 23 pin RGB port and what do you know... a nice floppy insertion animation comes to the screen. And the power LED flickers just like it did when I tried it with my default VGA setup.
There is no static electricity damage, there is no problems with the ROMs and not with the PSU either. That's all basic stuff I checked first. Static guard is one of the most intensively used chemicals in my shop on top of the protective carpet and the grounding wristband.
This board is just fine.
As for the donated board, I have no clue why I get a green screen but I don't think I will fix this soon.
And just so you know, I already tried swapping Agnus and both 8520 CIAs so these are not at fault. Neither is the PSU, neither are the ROMs or the daughtercard.
