Unisys A Series ?

Had this machine dropped on me last night... Can anyone tell me anything about it? So far, google etc. have turned up little. It's a "squat" format workstation or server of some kind: 11"w x 18"d x 21"h Front bears the name: UNISYS A SERIES Two doors reveal: Upper: Tape drive, CD-ROM, Floppy Lower: Power/Drive lights and key switch Two serial number labels on the back, a smaller one which says: Style: A7-311 And a larger one which says: Style: CER4344-100 One of labels inside says it was made in 1994. Appears to be somewhat "PC-ish": - Large maniboard with EISA slots - CPU card with 486 CPU and "OVerdrive socket" - VGA connector on back - PS/2 Keyboard and Mouse connectors - Also has serial, parallel, SCSI and UPS connectors. It also has a very large network card, and another card with more RAM and several large UniSys chips that I don't recognize (one with a large metal lid with the warning "DO NOT PRESS ON LID" printed on it!). It powers up, but reports that it's configuration is bad, and that I should run the setup disk. All I can do is press F1 to try and boot the floppy. Doesn't appear to be a PC - attempt to boot a DOS floppy results in silence (machine sucks on it for a while, then goes into la-la land). Attempt to boot a cleaning disk results in the message "Disk read error" and return to the "Press F1" prompt. (which suggests that it didn't have trouble reading the DOS disk). Can anyone tell me exactly what this is? What does it run? Any information would be appreciated.
