Re: HP 12C Production nmrs Message #2 Posted by Jeff O. on 8 Feb 2012, 3:15 p.m., in response to message #1 by Dominique Deprez Are you sure those are Q's and not 0's (zeros)? Assuming they are zeroes, the 2324A unit is oldest, having been made in 1983. The other was made in 1987. As for "best produced", I believe that all units from the 1980's are regarded as high quality. Edited: 8 Feb 2012, 3:16 p.m.
