The Bits and Bytes TV series featured a format where Luba Goy as the instructor would address Billy Van through a remote video link. The video link would appear to Luba who was seated in an office on a projection screen in front of her. She was then able to direct Billy who appeared on a soundstage with various desktop computer setups of the era.
Popular systems emphasized included the Atari 800, Commodore PET, Tandy TRS-80, and Apple II. Each episode also included short animated illustrations to explain key concepts, as well as videotaped segments on various developments in computing.
The above video is sort of cheesy in an 1980’s awesome kind of way, but still really informative, so if you have the time, it’s highly recommended that watch the entire thing.
