Aha! Another VAXBI survivor! The company I used to work for did a quad
IEEE-488 interface and a MIL-STD-1553 interface. I did the firmware for
the IEEE-488 interface (imaging a Z80 looking up user-space addresses
in the page table. Fun!) and the device drivers for both interfaces. We
did hardware debug by running CP/M on one of the IEEE-488 cards; that's
right, I have a VAXBI machine that runs CP/M.

We sold about a hundred or so IEEE-488 interfaces. It took many years, but
it did manage to climb out of the red ink. The problem is that the bloody
thing simply will not die; I've been averaging about one inquiry a quarter
on it.
