HP 12C Identification
How can I identify the processor and firmware used in my 12C's? Looks like HP has used Agilent/Marvell, Atmel, ARM cortex, and others and various firmware versions over the years..

Platinum 25th Anniversary single battery
CNA70707107 (China 07 of 2007)

Platinum dual battery
PHA1050249 (Phillipines 2021? just bought it)

Platinum dual battery
unknown serial

Still looking for an F2230A aka HP-12C+ two battery, ARM processor 12C. I did order a SwissMicros DM12L with the ARM microcontroller emulating the NUT processor and an LPC1115 32-bit ARM Cortex-M0 microcontroller.
