Hand-held typing device - UK - Mid 1980s.? Answered
Back in the 1980s I knew someone who used a hand-held typing device which worked by pressing 5 keys (one for each finger + thumb) to form characters. The stored text could then be downloaded via (I think) serial link to a PC. He used to infuriate lecturers by appearing to be sitting idly and not taking notes when he could actually operate this device at normal speaking speed and could print off a whole lecture transcript afterwards.
What was this device called and who made it?
