Is there a $F0 source/assembly file anywhere?

Not familiar with how GM did its software engineering back in the day, but I imagine they did not provide assembly source for their ECMs to just anyone who asked for it. Interesting reverse engineering problem.

There are some who got the code ?over the transim? and some who can disassemble the Motorola assembler code.

I would love to speak to those who can of you have a suggestion.

I would go to thirdgen.org. There are members there who have been responsible for many of the tools we have today for tuning, particularly OBD1.

Good idea. I cast the line and will see if anything bites.

Rgr. I was poking around last week for a motorola chip diassembler, looks there are a few running around of unknown (to me anyway) quality, and IDA may be able to do it in the paid version, still looking into that.

Any idea what type of processor these were these based on back in the day? I could try to lean on some of my professional contacts if I can give them a hint of what they're disassembling.
