One of those portable Apple II's was in "The Man Who Fell To
Earth", used by the English Language lecturer, not Bowie.
Incidentally (and also certainly off-topic), in the same movie a
rocket was launched (after a lengthy countdown sequence) by punching the
"TALK-TO-STUDIO" button on an SSL mixing console.
Strange how other things are sometimes used to simulate
computers in movies - like all those huge-with-lots-of-pretty-lights
mimic panels in every James Bond movie, even the later ones. They all
blew up, of course, with huge showers of sparks.
The best was HAL - all those perspex memory banks.
