 The Programmer accessory had been mentioned in the earliest advertisement but it was not featured until March 1974. This was the same size as a desktop calculator and could hold 256 programming steps. (It could be expanded to 512 steps.) It was limited to emulating calculator key presses and simple sequence branching. The programming was done by entering hexadecimal key codes. The combination of the MITS 7440 calculator and the programmer was not nearly as sophisticated as the HP 9830 calculator but $ 400 for both kits was a fraction of the HP price.
