Fascinating story about the development of the MingKwai device - designed to retrieve Chinese characters in an accessible way and then imprint the chosen character on paper.
With 72 keys and three keystrokes, it was possible to create the 80,000.
Only one, the prototype, was ever produced...
It was discovered in the basement of an Upstate NY house!
