< > 4004 trivia: I was told by the Fujitsu Elevator tech where I work < > that the five machines in our building are all controlled by a < > 4004-based system.. that apparently Fuji is still supplying in one < > form or another. < < Shure ? Or is it just the usual mix up of facts ? < Fujitsu (like NEC and a lot other companies) is < still producing several lines of 4 Bit controllers. < They also design _new_ 4 Bit singlechipers. But < AFAIR these are not compatible to the 4004 in any < way. This is very true. In the window of around 75 through now NEC, Hitachi, Fujitsu, Yamaha and others have produce their own 4bit data path single chip cpus. NEC had in the early days the uCOM-4 series and later the uCOM75 series. While each had some similarities to 4004 they were not compatable. They were also most widely used in games like Einstein, Simon, VCRs (timer), Microwave ovens to name a few. Allison
