Mauro72 Posted March 24, 2018 Share Posted March 24, 2018 Hi, I have this problem since blowup the first 74LS541N, the controller of port 1 and replaced with socket + new 74LS541N. No way to move up, the remain actions, fire, left, right, down are working. The Port 2 is Ok, all directions, fire, etc. Tested with 4 coleco original joyticks, all with this issue, no up movement. What pin control the up movement? May be a faulty track? Which? Any help? Thanks! Quote Link to comment Share on other sites More sharing options...
cdn2a Posted April 5, 2018 Share Posted April 5, 2018 Up is Brown, pin1 to gray. So pin 9 on the 74ls541 I believe. Quote Link to comment Share on other sites More sharing options...
