3.    Odd DEC single-board computer. 10" x
7" labeled DEC 54-16489, Has two
 84-pin PLCC chips
        with the LSI LIA 0433 and 0434 marks. Has a DB25, DB15, and DB9.
 Recognizable chips
        include 8051, FD1796, CDP 6402 (RCA), and D7201C (NEC) Can anyone
 identify this? 
Offhand, it sounds like a DECmate, probably a III.
