I could probably lend it out, as I have a hacked copy of RSX11M on it.
First I have to find the controller/power supply. Will check around next
time I'm up in the attic.

"SMD" was in fact a product name. The CDC976x, BK4XX, BK5XX, BK6XX, and
BK7XX series drives had the

I've been looking for one for a while to try to recover an early Sun Unix
if you don't have a need for it.
Oddly enough I have a 9457 Lark out in the shed. The trick is the SMD to
whatever it is connection is made in the power supply box, there is a
ribbon cable going from the box to up to two drives and an SMD interface
on the other side. Do you have the power supply?

Hello,
well maybe my memory has blank spots.
I have two CDC Lark Disk modules I would like to revive, they are in good
shape, but only one has a cartridge included, and they are not identical.
Not sure if the other one could be employed without cartridge.
I never found a manual with exact model cor

The division was Magnetic Peripherals Inc. (MPI). I've never heard of it
having been called CMD either before or after it was called MPI. There
Thanks Eric, I somehow missed that one.

X3.91M-1987 section 6 covers "Interface Extensions", which includes adding

ANSI has a spec, X3.91M_1987 I don't know if it covers the SMD-E , etc.

Hi,
I’ve been trying to find *detailed* specifications (mainly detailed signal
timings) for the SMD disk interface but all I’ve found so far are the interface
specifications for individual disks (CDC, Fujitsu, etc). I’ve looked in the
usual places (bitsavers mostly) and haven’t found the spec
