Mach 3 Crashing PC
Off hand do you recall which IRQ and memory address did you use?
LPT1 (built in) is at the normal 0x0378
LPT2 is at 0xDD00
LPT3 is at 0xDF00
All three are set to "never use an interrupt".
I use another PC control I'm really surprised you don't use an interrupt
with Mach. My control has an IO card that fires an interrupt if an input
changes state. The computer then polls for which input changed. How does
Mach trigger an event on an input change?
