Hello, I want to sent some data to the parallel port and give a pulse on one (or two) of the other pins but can't figure out any more how it works. I had it working several years ago but lost the source. I have connected a test PCB with a resistor and LED connected to ground on the parallel port, but when I sent some data with OUT &H91,A (I also tested it with call &HA8) RuMSX freezes.
Is there someone who can help me out? Greetings Cor -- For info, see http://www.stack.nl/~wynke/MSX/listinfo.html
