The 1978 Magnavox Odyssey2 computer video console running Computer Intro! program. The Odyssey2 had an Intel 4048 (MSC-48 microcontroller) CPU and full membrane keyboard making it a "computerette" (my term) when compared with its market rivals the Atari 2600 and Mattel Intellivision. Computer Intro! allowed the user to create and run 4048 assembly programs, although I am not aware of any way to save these programs. There was no cassette storage that I know of.

Magnavox Odyssey2 programs were stored on cartridges, and most were games. The keyboard was used mostly to make game option selections.
