I have an old BMW car radio. The code is missing. I'll attempt to get the code from the radio. It will involve some hardware hacking.
That code turned out to be driving the LPT port on an older PC to perform the memory dump! These were the times when one had direct access to the hardware pins from the CPU. Today, I can wiggle pins inefficiently with some lines of python.
