Chuck asks:
Anyone remember the
Fairchild F8? Around the same time as the 9440, the F8 was hugely
popular in embedded type applications.
Mostek's 3870, a derivative of the F8, was popular throughout
all sorts of mass-produced products in the late 70's and through the 80's.
STMicro had a chip that was very similar (clone? derivative?) of the 3870 that
appeared in consumer products in the 90's.
General Instruments certainly took a very similar microcontroller (now
known as the PIC) and built it up and out in several directions.
