The Kernal, the Basic or the Character ROM? I would also believe the RAM could be the faulty part, as the video matrix is in the RAM, and something like this might happen if the RAM doesn't work? Possibly unrelated: I own a switchable 32K RAM expansion which sometimes connects poorly, and thus is unusable until it is correct seated. If I switch on the 8K block at $A000, the screen is filled with garbage characters and locks up. /Anders Carlsson - This message was sent through the cbm-hackers mailing list.
