P.S. Does any one want me to upload a big PDF or two JPGs of the MC6809 Instruction Set Summary?

Thanks Alastair! You did a great job. I for one would prefer you to upload it as one big PDF document.

Thanks Phill! :) For some ROM calls I had to write a small (but fast) routine to identify the machine type and call the correct ROM routines. The machine type is identified by looking for $B4 at the ROM address $BFFF (Reset vector LSB). For the %POLCAT% and %OUTCHR% I simply added some indirect JMPs...

This version is patched to make it compatible with both Dragon and Tandy CoCo 1/2 machines. 8-) EDIT: Attached an improved version. This version removes some protection from the DEMON monitor which was intended to prevent the cartridge from being run in MAP1 (64K RAM) mode. The routine which identif...

This statement seems to indicate that DasmDemon is compatible with both Dragon and CoCo machines, but that's not the case with the version you uploaded because it calls Dragon specific ROM routines.
