Retro computer enthusiast Bill Kotaska has successfully built a replica of Busicom’s historic 141-PF printing calculator using vintage Intel chips. It’s the 37th anniversary of the world’s first single chip, customer-programmable microprocessor, the tiny Intel 4004. It was the Japanese calculator maker known as Busicom which later introduced the first product ever built around an Intel microprocessor.
So, in light of this historic event, Bill Kotaska decided to craft this re-creation of the historical machine which is capable of running the software from the original Busicom ROMs. Fancy yourself a computer historian? Bill’s got you covered as he provides schematics and photos of his re-creation at the unofficial 4004 web site, provided below.
