You could have said single chip CPU but in reality what does that mean as 8088 required a 8084a clock driver and many other chips in practical use are never quite single chips unless you mean an 8048 or 8051! <I didn't mention the 11/03 because although it's often described as a <microprocessor, it's actually a set of 4 40-pin chips (5 with optional <EIS/FIS instructions) called a D-11. That's the one often called an The KD11 was four chips (5 with EIS/FIS) but the distribution was CPU core and Micoms (microcode roms) around it. <sure there was a stand-alone system using RX02s.
