CS/80 disc geometry

[Al Kossow]

But I probably will need CS/80 docs of some sort.  There apparently is
some MI driver code for HP-IB disks in NetBSD, which is likely to help.
Unless there's some kind of CS/80 spec among the doc we have online...

the CS/80 programming spec is at
http://www.bitsavers.org/pdf/hp/disc/5955-3442_cs80-is-pm.pd

the AMIGO protocol is described in
http://www.bitsavers.org/pdf/hp/disc/09134-9032-Aug-1983.pdf

a piece that is still missing is what commands are supported
in the SS/80 subset protocol used in drives like the 9153C
and 9354A/B

The HPIB code for the 9000 code in NetBSD is the 'rd' driver
along with hpib.c
