I understand the demo you mention uses VSP / VIC in a specific way. That's why I say it _might_ be something about the VIC even if it shows no VSP errors. > The crashes are very repeatable infacts, all happens every time at the > same point of some programs. Which is a good thing. It's always better than those esoteric ones that show only once in a cyan moon. > I don't have any other MOS 8565 VIC-II chip to try swapping it.

You need to take care of the voltage it needs but for a test it should be feasible. -- SD! - http://e4aws.silverdr.com/ Message was sent through the cbm-hackers mailing listReceived on 2017-04-18 13:00:02
