Well, I'm grasping at straws, but maybe check Gary 5719?  (Could be Gary is not letting the 68000 access the bus TO the ROM?) (shrug)

I'm really more of a hardware guesser than a specialist, though.  :lol:

On amiga 500's a red screen is very common.
try reseating the Fat Agnus chip , also check the pins on the Agnus socket.

Cheers

I've had a similar problem with A2000. At boot, I was getting the red screen, however the system would still go pass it and boot fine. When I replaced the Denise chip with another one, the red screen went permanently away. :-)
