The museum is looking for the MITS (which stood for Micro Instrumentation and Telemetry Systems) 7440 Programmer unit. This device, connected to the MITS 7440 calculator, was availbale in assembled or kit form. The programmer provided a means by which the 7440 calculator could be programmed, with programs ranging from 128 to 256 steps (depending on the amount of memory installed in the programmer) in length. Programming capabilities included looping and branching functions, allowing for rather complex operations to be performed automatically. Advertisement above is from the 1974 timeframe.
