HP-12C Production/Models History
I am trying to get a picture of the production models/history of the 12C.
Some google research, this site and the blog from Max Stone was very helpful to make it.


Model,           KeyBg,  Beg-End Prod, Prod. Site,   Batt., CPU, Comments
HP-12C,          Black,  1980-1995,    A/S/B/M,      3x357, 1LF5-0301/1LM2-0001/LQ9-0322/1RR2-0001, not clear which of the 4 CPU is with this line or the next
HP-12C,          Black,  1996-200?,    US/SG/MY,     3x357, 1LF5-0301/1LM2-0001/LQ9-0322/1RR2-0001, end of prod. is before 2004
HP-12C,          Black,  200?-2004,    CN,          1x2032, 2AF1-0001, begin of prod. is before to 2004

HP-12C Prestige, Gold,   2005-2006,    CNA/4CY,     1x2032, SPLB20D, revised & based on 17BII+
HP-12C Platinum, Black,  2005-2010,    CNA/4CY,     1x2032, SPLB20D, based on 17BII+
HP-12C 25th Ed., Black,  2006,         CNA/4CY,     1x2032, SPLB20D, based on 17BII+
HP-12C 12+,      Black,  2009-today,   CNA/4CY,     2x2032, AT91SAM7L128, none
HP-12C 30th Ed., Black   2011,         CNA/4CY,     2x2032, AT91SAM7L128, none
HP-12C Platinum, Black,  2010-today,   CNA/4CY,     2x2032, SPLB20D, none
Is the above table represent the reality ?

Production site letter G stands for Germany. Not sure whether they really made pocket calcs in Germany.

Slightly OT: I had some heavier bricks which were made in Germany: An HP 64100A (Desktop), an 64110A (Portable), and a really heavy (more than 200kg!) HP 250 Business Computer, and I think some of the desktop computers were also made in Germany.
