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.
