You won't find it under that name, as "HP-12C+" was only a nickname. It was marketed as "HP-12C" (F2230A) since 2008. Like your 2011 "HP 12c 30th Anniversary Edition" (NW258AA) model, it is based on the Atmel AT91SAM7L128 controller and takes two parallel CR2032 cells. While the processor is EOL and no longer in production since a number of years, the F2230A model is still available new for about 50 EUR in many shops - at least I am not aware of a newer model variant of the HP-12C, which had to be based on a different processor then.

Quote:All I see for sale is the 12C "Gold" with one CR2032 battery that I suppose is the current HP production model.

The HP-12C with only one CR2032 battery is an older model variant marketed between the late 1990s up to 2007. It is not based on the AT91SAM7L128 and not reflashable. I don't know the MPN of this variant.

Note that the original 2003 "HP 12c Platinum" (F2231A) model was based on the Sunplus SPLB20D2 processor and is not reflashable. The later "HP 12c Platinum" (F2232A) models, the "HP 12c Platinum 25th Anniversary Edition" (MPN unknown) and the "HP 12c Prestige" (F2233A) are all based on a Generalplus GPLB31A processor, not reflashable as well.
To complicate matters, several model variants are sailing under the F2232A label, the latest variant (since 2010) takes two CR2032 batteries (just like the F2230A). Nevertheless, while the 2010+ F2232A model of the 12c Platinum continues to be based on the GPLB31A, the 2008+ F2230A model of the 12C is - to the best of my knowledge - still based on the AT91SAM7L128.

To even further complicate matters the very latest 12C (regular, not sure about the Platinum) is based on a Atmel SAM4L processor (because the SAM7L was EOL as you said) -- the AT91SAM4L-EK -- that uses the same 6-pin interface for programming but it's USB not serial and therefore requires the use of cable with the same connector but without the USB-to-serial chip.

There are so many different versions of the 12C out there it's nearly impossible to keep up with them.
