HP-12C: The longest production run in the industry?
(Updated "HP-12C_variants V0.5" document)

I like a good mystery (or absence of information in this case) to talk about and investigate when one is in the mood and have time to spend on that.

So I have compiled a small table with the HP-12C variants, using the public available information here and there and crossing it for validation.
I'm sure it contains errors as a result of this investigation process, but it can be updated when more trusted information comes around.

Note:
This listing may not be up to date.
Please use the attached word documents for more detailed and updated information.
