Comment by Martin Krause (mkrause[at]fastmail.fm): I have/had an NEC V20. It was great; the extra speed was like something for nothing. It also runs much cooler than the Intel 8088 as it used CMOS instead of NMOS. I once built an all CMOS motherbourd with it and a bunch of other descreat logic like 74HCxxx instead of 74Sxxx. I was trying to build a PC that produced very little heat and therefore required little cooling.
