OK, I stand corrected. No eggs please :-). I was merely speaking from experience with interrupts in micro controllers and such. I didn't know that IBM botched it so badly. Well, this probably rules out interrupt sharing on an ISA bus. At least, without some hardware hacking (as several people pointed out), which is not _that_ hard, but not really worthwile (I think) if you can get a cheap multi-port board.
Sorry for the confusion.
Cheers
