The microprocessor has changed our lives in so many ways that it is difficult to recall how different thing were before its invention. ... In exchange for the return of Busicom’s $60,000 investment, Intel was able to retain the right to the product and establish a strong foothold in the microprocessor industry.
The worlds first general purpose microprocessor, the Intel 4004, was designed by Intel’s Ted Hoff, Stan Mazor, Federico Faggin, and Busicom’s Masatoshi Shima. ... This chip contained 3,500 transistors and an 8-bit microprocessor which allowed it to manage alphanumeric data. The first commercial computer to use a microprocessor, the Micral, used the Intel 8008 chip. ... The 6,000 transistor microprocessor had 16-bit addressing, an 8-bit data bus, ran at 2 MHz, contained a 16-bit stack pointer to memory, and could address 64K of memory. ...
Faggin and Shima teamed up in 1975 to develop the Zilog Z80 microprocessor. ... This microprocessor was the first to be used in many pioneering systems including the Osborne and the Kaypro.
