I reviewed the text file on the nondiode IRQ hack. It states that you put the
6809-end of the wire on the side of the IRQ line resistor that is opposite the
6809 (i.e., not directly to it). That could have been a problem source. Also,
it is my understanding of the text that you keep the 6551 and 6809 IRQ's tied
together only when you are using the serial port because of the recommendation
you use a plug/jack pair (enabling you to detach the hack) instead of a direct
connection; I may be wrong on this point though.
