since I didn't find Jon's post on the interrupt process.
Some reading of pdp wiki, etc refreshes memory (slowly).
There were 4 interrupt lines which gave only 4 levels of interrupt.
Then interrupts were further arbitrated by the position of the
interrupting board on the bus.

I'm sorry, Gene, that you had such a bad experience. I can only protest
that a PDP11/23 wasn't a *real* PDP11. It came out nearly a decade after
the 11/20, had an LSI-based CPU instead of a boatload of M-series logic,
used the Q-bus instead of the Unibus,
