Kenbak-1是被计算机历史博物馆和美国计算机博物馆认定为世界上首台“个人电脑”[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]
由于 Kenbak-1是在第一枚微处理器发明之前诞生的，所以这台机器没有单芯片CPU，而是完全基于小规模集成TTL芯片[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.
