Condition: Mint / excellent appearance-57 year old piece of history. Clean board, intact chips, very minimal corrosion, no broken traces, no missing ICs visible. Copper power bus bars intact and in complete shape.

Description:

Original late-1960s Unisys / Sperry Univac printed circuit card assembly. These boards were used in Unisys digital computer systems (military and commercial lines of that era, including systems related to the Univac 1219 family and similar). Drop-in sections that accompanied these boards have already been verified as matching.

The board uses classic Texas Instruments SN74-series TTL logic:

• SN7400N

• SN7440N

• SN7473N

• and other 14-pin DIP 74xx parts

Date codes on the ICs are in the 69xx range (1969 production).

Ten long copper bus bars run the length of the board for power and ground distribution — typical construction on these high-density Unisys logic cards.

Markings visible on the board include:

• 0740

• 44P0023 (or close variant)

• VDM

• 40D0034

• DM 121

• additional Unisys-style assembly stamps

Approximate size: ~16–17 inches long (see tape measure in photos).

This is a large, densely populated, visually striking vintage computer logic board. Excellent display piece for a vintage computing, military electronics, or early TTL collection.

Not tested for function (sold as-is for parts or display).

What’s included:

The board shown. No cables, no additional modules unless noted in photos.

Shipping:

Will be packed securely with board support so the copper strips and ICs are not bent or damaged in transit.

Serious collectors of Unisys, Univac, Sperry, early TTL, or 1960s military computer hardware — this is a clean example.
