    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
