Tschibo00 Posted March 12, 2006 Share Posted March 12, 2006 Hi there, in the old days I modded my 130XE, that it had a hardware switch to switch BASIC on/off on boot. Unfortunately I don't have the magazine anymore, where the schematics was in. Lateron I removed the switch but seemed to have something screwed up. In the moment, my trusty Atari won't boot in BASIC, but just in the Selftest, whether I press Option or not. Does anybody have the schematics of the BASIC switch or can help me what could be wrong? Thanks! Christoph Quote Link to comment Share on other sites More sharing options...

Thanks! Christoph Pin 18 of the MMU (CO61818) controls the BASIC select. On a stock 130XE, this is connected to PB1, pin 11 on the 6520 PIA if you want it controlled through software.

Tschibo00 Posted March 15, 2006 Author Share Posted March 15, 2006 Oh, thank you very much! I now (again) have a hardware switch to disable BASIC or to have it software controlled. Maybe I should take a closer look to the schematics more often Quote Link to comment Share on other sites More sharing options...
