Experimentation by correspondence
The notion of a correspondence course was transformed when the OU started to send out home experiment kits and computers by post.
This is HEKTOR, a ‘home computer’ dating from 1982. It could be plugged into a TV which became its monitor and plugged into a cassette recorder for storage. Initially students were encouraged to write programs in BASIC but later it was used for other purposes, including on a control engineering course.
