When we were configuring the parallel port, we had to disable IRQ (7 I
think) and TT had to do it in software (by timing carefully - ie
slowly!).
The hardware needs a permanent change in state but the ISA hardware
provides a pulse, which is not seen by the Q40 hardware. I think the
Q60 is the same. Peter said at the time there was no spare logic left.
Peter needs to be consulted here I think - as my knowledge now is
probably way out of date, and Peter may have found a way of 'seeing' the
IRQ pulse.
