- Of course, some cards are created with the thought of sharing interrupts
- in mind. If they only use a pull-up resistor on the board to take the
- signal high, then there is no problem with sharing the same interrupt.
- However, if just one card on a given interrupt uses an active pull-up
- (such as the output of any non-open-collector TTL part), then the
- interrupt cannot be safely shared. You may get away with it, but it
- probably won't last for ever.
