Oooo ... transputers :-)
Transputers caused much dribblage when I pretended to be a comp sci student.
Had to learn parallel processing techniques and Occam ... Very confused lectures, resulting in an unforgettable question from a student to a young lecturer "... but aren't you making this up as you go along?" The lecturer admitted that the stuff was so new that he was about a day ahead of us ... at which point we all softened our attitudes towards him as we realised that he was trying to keep us on the crest of a technology wave ... even if it meant buying the worst value book in history "The Occam Programming Manual" by Inmos which had multiple pages inscribed with the phrase "this page is intentionally left blank".
