HP-12C Production/Models History - Sylvain Cote - 01-12-2014 04:58 PM

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.

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.
