The making of the Intel 4004 design

I was at a company yesterday and they had made a calendar of chips and whatnots. Alas, the only page I got to see what the one for this month: the Intel 4004 - the world's first commercially available, general-purpose, single-chip microprocessor.

Of course, I had already made a shirt with it.

Here's the making of the design.

Enjoy.
