Intel You may not realise it, but today one of the most important pieces of technology celebrates its 40th birthday. In November 15, 1971, a company called Intel released its Intel 4004 processor - the first single-chip microprocessor, and one of the most important milestones in computer history.

Although the 4004 chip was cheap enough, by the time it was packaged up into a useful system, the cost was back in the many thousands. The tiny bus meant lots of external glue logic was needed. The 8008 was a little better but the switch to NMOS in the 8080 is what allowed lots of rapid improvements to start coming in plus competitors. The 8080 finally had a big enough 40 pin package that allowed the address and data buses to be direct driven, most of the glue logic was gone.

I used to love watching Tomorrows World and Raymond Baxter mentioning "it has a built in Micro Computer.." every time he opened up the gubins box to show these new fangled things.
