VISIBLE TABULATING BOARD CIRCUIT
This antique computer board, found in an old government warehouse, was probably manufactured between the 1960s and 1970s. Made from aluminium, the frame has a plethora of wires, sockets and plugs. The wires are bound together using couplers that have IBM written on them. The frame has the words “Visible Tabulating Supply Corp” marked on it. The dimensions of the module are: Width 19 inches and Height 11 inches. This vintage piece of tabulating board circuit would be a jewel in any computer aficionado’s collection.
