I googled up a brochure, and from the front it appears to be based on the same chassis as my PS/2 85. I guess it was meant to be an external SCSI enclosure for machines of that era? I believe that the 85 was intended for server duty, so a matching external drive enclosure makes sense to me.

My machine came without its original hard drive, so I substituted a SCSI2SD. I also added a SCSI CD-ROM drive that I harvested from one of my Sun Ultra 60 stripped chassis, then used that to install OS/2 on it.
