TRS-80 Cassette Interface

'The TRS-80 Cassette Interface was combined with the Radio Shack PC-4 calculator for a few scenes in the first movie. The Interface provided a means of data storage between the PC-4 model calculator and a tape recorder. Programs could also be loaded via the interface from software tapes available at that time.

Part Number: 26-3651.
