12C+
Message #1 Posted by Charles Oxford on 28 Sept 2009, 11:48 p.m.

I read somewhere (I think on hp site) that the 12c+ can't be repurposed to scientific calc. What then would be useful repurpose?

On friday I was in Fry's for batteries and printers so I checked the calcs on my way out. The last time I was there (maybe 2 months ago) they had 7 of the older 12c's. This time there were only 2. They don't seem to move very quickly. I asked an employee in the aisle about their stock but he didn't know.

I would be interested to hear about any repurposing done thus far.

Also, is the same equipment needed as for the uWatch?

See HERE for info on the 12C repurposing.

Sorry, doesn't use the same micro as the uWatch, it uses an Atmel ARM processor with a serial interface (is the JTAG interface is accessible?). So you need either a suitable serial cable I believe HP sells?

Totally different development environment to the PIC too.

A scientific version would be easy in software, but the problem remains that of the keys have the finance legends on them.

It's surely just a matter of time before HP release the exact same machine with the original HP15C ROM and keys. I'm surprised it's taken this long already.
