The IBM Enhanced Keyboard turns 40
(sharktastica.co.uk)
On this day, in 1985, IBM announced the 7531 and 7532 Industrial Computers. Two AT-derived computers that were "designed for information-handling applications in industrial plant floor environments". The announcement letters only lightly touched on their keyboards, noting their bidirectional serial interface, mode indicators and separated typewriter and numeric keypad sections - all inherent to any AT-based keyboard. But this keyboard was actually so much more than what was led on. IBM worked to enhance them, aptly calling them... the Enhanced Keyboard.
