I am trying to determine when the NEC V series CPUs became available. So far I have:
1982 µPD8088 1984 V20 ???? V40 ???? V41 1981 µPD8086 1984 V30 1988 V33 ???? V50 ???? V51 ???? V53 1986 V60 1987 V70 1989 V80
Can anyone fill in the unknown ones?

I got some info by going through December Byte issues, so that will start things off. Others can fill in from whatever info they can find. I chose Byte since their coverage was quite broad, and the December issue to narrow things down to a given year. However, it is US-centric, and the NEC chips never penetrated deeply into the US market. However, mentions were slimmer than I would have thought, particularly with respect to ads from standard parts suppliers (at the time) such as Jameco - at best I found mentions of the various V20 and V30 versions, nothing past (even as late as Jameco's Feb-Apr 1994 catalog, all that are listed are the V20 and V30s). I suppose Computer Shopper would be another good option, but I have not had the time to get to those.
Data so far, collected from Byte, Wikipedia and other sources:
V25 μPD70320 (or μPD70322 with custom ROM)
V30HL μPD70116H - an optimized V30 core with non Intel pinout
I strongly suspect that a search on Asian or European magazines may well yield more and better data.
