The Intel 8008 was an early CPU designed and manufactured by Intel. It was released in April 1974 running at 2MHz, and is generally considered to be the first truly usable microprocessor design. It was used in many early computers, and formed the basis for machines running CP/M.
The 8008 was twice as powerful as the 4004. A 1974 article in Radio Electronics referred to a device called the Mark-8 which used the 8008. The Mark-8 is known as one of the first computers for the home –one that by today’s standards was difficult to build, maintain and operate.
