Vintage UNIVAC Mainframe Computer Logic / Timing Circuit Board – 3620670-01
Original vintage UNIVAC plug-in circuit board / module, believed to date from approximately the late 1970s or early 1980s.
Board is marked UNIVAC and 3620670-01 and features a large CTS Knights 15.0 MHz oscillator, multiple Texas Instruments and other period integrated circuits, front-panel indicator lights, two toggle switches, and a large backplane connector.
Several ICs carry apparent 1979 production/date markings, consistent with late-1970s manufacture. Exact UNIVAC system and original function have not been confirmed.
This is an unusual surviving piece of vintage enterprise/mainframe computing hardware and would make an excellent addition to a UNIVAC/Sperry collection, computer-history collection, museum display, or vintage electronics collection.
Visible markings include:
