NEC V60
The NEC V60 is a CISC microprocessor manufactured by NEC starting in 1986. Several improved versions were introduced with the same instruction set architecture (ISA), the V70 in 1987, and the V80 and AFPP in 1989. They were succeeded by the V800 product families, which is currently produced by Renesas Electronics.

The V60 family includes a floating-point unit (FPU) and memory management unit (MMU) and real-time operating system (RTOS) support for both Unix-based user-application-oriented systems and I-TRON–based hardware-control-oriented embedded systems. They can be used in a multi-cpu lockstep fault-tolerant mechanism named FRM. Development tools included Ada certified system MV-4000, and an in-circuit emulator (ICE).
The V60/V70/V80's applications covered a wide area, including circuit switching telephone exchanges, minicomputers, aerospace guidance systems, word processors, industrial computers, and various arcade games.
