The Wall St. Journal had a good essay about that, by Andy Kessler.

The subtitle is "Most of the wealth created since 1971 is a result of Intel’s 4004 microprocessor" which seems extravagant until you read his arguments. I still remember the 4004-based personal computer a college classmate of mine designed and built in 1974. It was a large (DEC Unibus hex module sized) wire wrap board with about 100 chips on it. And it worked. Slowly, but it could do useful programs. paul > On Nov 16, 2021, at 12:30 PM, Zane Healy via cctalk <cctalk@classiccmp.org> > wrote: > > It looks like the Intel 4004 turned 50 yesterday. > > Zane > > >
