danwinslow Posted March 23, 2005 Share Posted March 23, 2005 I am seeking information about how to program the atari 130xe joystick ports for input as well as output. I gather you set a bit in PACTL and then set or clear bits in PORTA...I hope I got that right. Anyways, is it possible to read/write the trigger the same way? Any info appreciated, thanks.

danwinslow Posted March 25, 2005 Author Share Posted March 25, 2005 Thanks, I did. The question remains about the trigger button, though. Quote Link to comment Share on other sites More sharing options...
DanBoris Posted March 25, 2005 Share Posted March 25, 2005 The trigger inputs are read only. They go through the GTIA chip and are read at addresses $d010,$d011. Dan Quote Link to comment Share on other sites More sharing options...
