Done!
I have some specs. if it's not enough I'll get the rest by hook or crook!
I could use a hard drive in my Integrals!

This gets discussed by PERQ-fanatics from time to time (PERQs use strange
hard drives - SA4000s, Micropolis 1200s, ST506 interface things that are
no longer available). I've got a few schematics sort-of sketched out
(microcontroller + buffer RAM + ROM + GPIB chip + SCSI chip, for example
(or maybe I'd bit-bang the interfaces using parallel port chips).), but
I've not figured out how to write the control software yet.
In fact what's really holding me back is that I don't have a
specification of the CS/80 or amigo command sets (the commands that HP
used for their drives, and which are sort-of a de-facto standard). If
anyone has this spec, I'll consider building this interface.
