Happy First Commercial Central Processing Unit Day!

It was 40 years ago today (more or less): “The Intel 4004 was a 4-bit central processing unit (CPU) released by Intel Corporation in 1971. It was the first complete CPU on one chip, and also the first commercially available microprocessor. Such a feat of integration was made possible by the use of then new silicon gate technology allowing a higher number of transistors and a faster speed than was possible before.” And think of all the joys it’s brought us! Seriously, think about it.
