not exactly a keyboard, more like interface of altair 8800 from https://www.youtube.com/watch?v=W5d_1EqRi1U (video about Lancaster TV Typewriter) First one, Micral N, in 1973. By Réalisation d'Études Électroniques (R2E). In 1974, a keyboard and screen were fitted to the Micral computers. In 1986, three judges at The Computer Museum, Boston – Apple II designer and Apple Inc. co-founder Steve Wozniak, early MITS employee and PC World publisher David Bunnell, and the museum's associate director and curator Oliver Strimpel – awarded the title of "first personal computer using a microprocessor" to the 1973 Micral.[3] The Micral N was the earliest commercial, non-kit personal computer based on a microprocessor (in this case, the Intel 8008).[4] The Computer History Museum currently says that the Micral is one of the earliest commercial, non-kit personal computers.[5] The 1971 Kenbak-1, invented before the first microprocessor, is considered to be the world's first "personal computer". That machine did not have a one-chip CPU but instead was based purely on small-scale integration TTL chips.[6]
