One of the faster regular XT processors out there! The NEC V20 is a reversed engineered Intel 8088 processor and is slightly faster despite it runs at 8MHz as well.
I installed the NEC V20 in my ARC ProTurbo 88 system (came with Intel 8088 fitted) and noticed faster boottimes and the CPU seems to run a bit cooler as well.
