I just re-read that old 2011 thread and I see that at the time I could not find my M12 eprom, which didn't matter too much as it was the MS12 eprom (for the CPU PCB + Serial PCB) which people were after at that time.

I've just found my original M12 eprom now, so if the source MrBungle pointed you to doesn't contain what you want let me know and I will read it and post the code here. I see you obviously must have a keypad / display PCB to go with the CPU, I missed that on the first read.
