What I have are the docs for the MSC-9305 ST506-GPIB interface
which used the Xebec module. At one point it looked like the
commands were compatible.

That rings a bell. MSC is what Xebec was before they changed their name.
Not long after that they replaced the brick with the WD1710.
(dunno what they called themselves after...)
Thanks!I'll take a look.

I've got a very rough (changes inked in) programming document for the
MSC-10XX (yes, that's what it says) controller. It connects to a
SA-400x (14" drive) and has a GPIB interface (I have the drive and
controller). The board is very large--almost the same area as the
drive itself. No bricks.
An early instruction sheet I have for a Xebec drive proudly calls out
the drive "Perameters". Spelling must not have been one of their
strengths.
Cheers,

That board is fairly close to what i have. My board is
bigger and uses
dual row headers for the drive connections. it has no edge connectors at
all.
It looks like it's about 6 inches wide and about 9 or so inches long.
There are no edge connectors on it.
The DIP switch selects device address, drive type and format. There is a
button and LED for selftest, several
jumpers dispersed around the board. I think it uses an 8051 with the
UVEPROM window (but it may be an 8048) with external 2K or 4K UVEPROM. I
don't recall whether it had external RAM or not.
The board connected to the two 5Mb's can make them each look like four
HP 8-inch floppy's or one 4.8Mb disk.
The board connected to the 10Mb disk, in it's original Xebec enclosure,
can do the above plus handle a 10Mb disk but I don't think it can format
it properly.
I guess I'll have to take a few days off and dig into storage to see
exactly what I have and take some of them there geekpron pix...

HP's number for this OEM board--by MSC/Xebec is 88134-69910, 09135-69515, and/or
09135-69501. I have no idea which number belongs to mine.
The boards have the big black brick on them with the part or model number of
"9056", used before the switch to the WD disk controller IC.
A MSC disk unit was sold on Ebay recently, which contained a board that is at
least physically identical.
