Atari PAC-MAN Fan Posted June 25, 2017 Share Posted June 25, 2017 Hey Guys! There is a problem with my VIC-20 in which it keeps pressing up without me doing anything. I looked at the control-port, and it did not look like any of the pins were bent. Anyone know what's going on? Quote Link to comment Share on other sites More sharing options...
norm8332 Posted July 6, 2017 Share Posted July 6, 2017 (edited) It could be a stuck joystick or a 6522 VIA chip. Unplug the joystick. If it still goes up you may have an issue with a 6522 chip. If they are in sockets then try to re-seat them. if that doesn't work you may need a replacement. Edited July 6, 2017 by norm8332 Quote Link to comment Share on other sites More sharing options...
