Generic PC with V20 CPU (c) 1982 None

The NEC V20 was a processor made by NEC that was a reverse-engineered, pin-compatible version of the Intel 8088 with an instruction set compatible with the Intel 80186.

- TRIVIA -

The chip featured much more than the 29,000 transistors of the simpler 8088 CPU, ran at 5 to 10 MHz, and was around 30% faster (application dependent) than the 8088 at the same clock speed, primarily due to faster effective address calculation, along with faster loop counters, shift registers and multiplier.
