Kenbak-1是被計算機歷史博物館和美國計算機博物館認定為世界上首台「個人電腦」[1] Only 40 machines were ever built and sold. It was designed and invented by John Blankenbaker of Kenbak Corporation in 1970, and was first sold in early 1971. The system first sold for US$750.[2] Only around 10 machines are now known to exist worldwide, with various collectors. In 1973, production of the Kenbak-1 stopped[3] as Kenbak failed and was taken over by CTI Education Products, Inc. CTI rebranded the inventory and renamed it the H5050, though sales remained elusive.[4]
由於 Kenbak-1是在第一枚微處理器發明之前誕生的，所以這台機器沒有單晶片CPU，而是完全基於小規模集成TTL晶片[5]。The 8-bit machine offered 256 bytes of memory.[6] The instruction cycle time was 1 microsecond (equivalent to an instruction clock speed of 1 MHz), but actual execution speed averaged below 1000 instructions per second due to architectural constraints such as slow access to serial memory.[5]
To use the machine, one had to program it with a series of buttons and switches, using pure machine code. Output consisted of a series of lights.
