The NC-2 was sold 1976 and 1977. Replaced by the NC-77 in 1978...a classic calculator which continued in production until 1991. It was replaced by the NC-2000 (mainly?) because the almanac in the NC-77 falls over post 2000, see: http://www.tamaya-technics.com/nc77user.htm for a fix to keep it going until June 23, 2007. I have a vague recollection that the almanac in the NC-2 falls over sometime in the mid 90's...can't be sure. Lee Martin
