The Intel 4004 microprocessor turns 44

mcpublic writes: Today is the 44th anniversary of the Intel 4004, the pioneering 4-bit microprocessor that powered the first electronic taxi meters. According to the unaffiliated (and newly renamed) Intel 4004 45th Anniversary Project web site, they have just re-created the complete set of VLSI mask artwork for the 4004 using scalable vector graphics, and
updated their Busicom 141-PF calculator replica aimed at collectors and hobbyists. Included is some interesting historical perspective:
Back in the early 1970s, there was no electrical CAD software, design-rule checkers were people, and
VLSI lithographic masks were hand-crafted on giant light tables by unsung "rubylith cutters."
