I picked up a nice rack mass storage array with a bunch of 9g
drives in it.  The rack is powered by a differential controller that
runs to three boxes of drives that are 68 pin scsi (non-differential).
I would like very much to run one of the drive trays externally on
my Ultra 1.  I can't seem to find any model ID info on the mass
storage cabinet or the individual drive trays, so I can dig up some
docs on the critters.  The only numbers I can find are:

  540-3005

and

  540-3234

each holding 7 drive boxes,  540-2942.  It appears they are wired
for 240v, and I need to find out if they can be switched to 110v.
The label on the back has a possible model number OSM-3000-02
with a part number 501-8745.

None of these numbers seems to key out on a search.

Any insight as to what they are, and where some docs might be,
is appreciated.

Thanks

Bob Keys
