HP-12C+_Jose.bin
Jose from Calculatorstore sent me this as the latest rom for the older HP12C+
He mentions here New flashing service that he successfully flashed this onto the HP12C+ older version (pre 2015)

I have tried it and can confirm it does work! Thank you!

It shows as checksum 2424h and version 2009-11-19.

I have done limited testing, but it seems to be all functional.
