About the interrupt time for the new //e ROMS:
The manual for the Enhancement Kit, as well as the new reference manual,
says that the interrupt handler takes AT LEAST 150-200 microsec. to call
your handling routine, and 40 to 140 microsec to restore after. This is
assuming the interrupts are not hnadled through ProDOS's interrupt
dispatcher, which takes even more time.
The books don't say what the MAXIMUM time is to call your handling routine.
