Both of these chips have been identified and are in the p12 and e40 ecms. The main chip is a mc68377 and the little chip is the mc68f375 and we have bdm diagrams for both already.

This has internal memory and is a MC68HC11E9 which I believe is an early attempt at a slave chip. For the main cpu it's a 68332 which I don't believe contains any onboard accessible memory The e40 slave chip I believe is the newer version of this design going from 8 bit to 16 bit.. I 99.999999% beli...

This adds OS ID 12601904 to the list of known 1mb P12 operating systems. 12589586 is also apart of the p12 line up, can I get a copy of a bin with 12601904 to try and update my os? Its up above, however i highly recommend not switching over to this OS unless your on a bench with recovery tools.. IF...

it does identify as a p01-p59 upon startup of hammer

This OS is from saturn, so it is possible the unlock algo differs. Can you run this script with this program. It will test if pcm uses standard algo. https://pcmhacking.net/forums/viewtopic.php?f=42&t=7753 post results here. Here is the binary from that pcm if it helps 05 RL 124073 primary.bin

Please note that the P12 support does includes support for the 2Mb P12b PCMs. For P10/P12/P12b we are looking for reports of success or failure from in vehicle testing when changing the OS to another type.
