Unisys "Micro A"

Unisys "Micro A" Anybody know about such a system? I took in a stray cat system a few months ago, started parting it out, saw something interesting, then put it all back together again. Today I booted it up (fits on 15A, hurrah!) and determined the following: Base system: Intel mobo w/8MB (** 80386, sorry **) Adaptec SCSI OS/2 on SCSI disk internal SCSI tape (QIC) external SCSI tape (DAT) VGA card Add-Ons: Unisys "Micro A" CPU card (perhaps DC113) daughter memory card two multiplexed serial cards Another Adaptec SCSI card, apparently for the Uni half of the system. Another Internal SCSI drive two external drives Surprized it actually does stuff. The "Micro A" system is controlled by three OS/2 Apps: Admin, ODT 1, and SCS (System Control Subsystem) (nice name) (huh?). ODT 1 is a cryptic CLI system, SCS is a boot console for the HW Anybody got any beans to spill on this? is it just a big printer controller? I noticed the Micro A is apparently microcontrolled. What was it sold for? John A.
