From https://github.com/RevCurtisP/MC10/blob/master/disasm/MC10%20Disassembly.txt Seems the best disassembly that I can find. I have no assembler for the 6803 so I have not verified it. I have tried assembling it with macros for the extra instructions, and found there are errors in it. The author should have mentioned it is a work in progress.
