GroovyBee Posted July 19, 2010 Share Posted July 19, 2010 You could use the PIA for the SIO/DB9 lines as well as for bank-switching as done on Atari 130XE. It's not just the command line, the cassette player uses the motor line from PIA and I'm using proceed line as well. As I mentioned previously there is no A8 PIA. The RAM bank switching is handled by a PLD on PCB. Quote Link to comment Share on other sites More sharing options...
