First Personal Computer

In 1975, Ed Roberts used the term “personal computer” when he introduced the Altair 8800, although the first personal computer has been considered to be Kenback-1, which was introduced at a price of $750 in 1971. The computer relied on a series of switches for inputting data and output data by turning on and off a series of lights.

The Micral is considered to be the first commercial non-assembly computer. That computer was installed with an Intel 8008 processor and sold for $1,750 in 1973.
