And as earlier discussed:
RTC, prom, interrupt controller, serial ports.
Now, I do have an old spec that describes the parallel port
as a seperate chip, but I am nearly certain we folded it into
hpc3. I may have to retract that though. None of the specs
I have in my office are the final versions, and I don't have
an indigo2 lying around to look at the final chip layout. If
you find a chip marked PI1, then I am remembering wrong, and we
did the parallel port as a seperate chip.

I don't remember, and I don't have the Indy specs handy, and I can't
find the online docs right now. I think it went on the pbus, but
that's a vague memory.

Only the Indigo2 series (r4k, r8k, r10k) and Indy.
