mcpublic writes "For the 37th anniversary of Intel's 4004, the world's first COTS,
customer-programmable microprocessor launched on November 15th, 1971,
vintage computer
enthusiast Bill
Kotaska has successfully built the first replica of Busicom's
historic 141-PF printing calculator using vintage Intel chips.
Decades before the ubiquitous 'Intel inside' sticker, Japanese
calculator maker Busicom introduced the first product ever to sport an
Intel microprocessor inside. Bill's homebrew replica includes a rare
Shinshu Seiki
Model-102 drum printer and runs firmware extracted from the original
Busicom ROMs. Schematics and photos of his re-creation are available
at the unofficial 4004 web site,
along with Tim McNerney's new PIC-based emulator of the Model-102
printer.
As
reported here last year, the web site includes the Busicom 'source
code', 4004 details, interactive simulators, and other goodies for
students, engineers, and computer historians alike." Link to Original Source
