  I don't remember much about these, but I do recall a "stand" shaped
like this:
     _|   |_     (fixed-width font required of course)

  ...that the drive mounts atop, and then underneath that would be one
of the various SCSI<->QIC-02 or QIC-36 adapters for the tape drive.  A
hard drive mounted on its side, either to the left or the right of the
tape drive, I don't recall which.  The hard drive would be a 5.25" FH
device, either native SCSI, MFM via an Adaptec ACB-4000 SCSI<->MFM
adapter, or ESDI via an Emulex MD-21 SCSI<->ESDI interface.

  I'm pretty sure I have at least one of these boxes.  If I run across
it I will take pictures of the innards.

As I recall these had a disk drive and quarter inch cartridge tapes for backups.  Never cracked one open so don't know much about mounting devices inside..
