Robotron 2084 Disassembly

It’s been a few years since I worked on my Robotron 2084 disassembly, but I’ve recently gotten the bug to modify my machine, so today I finished a decent portion of the disassembly. I needed the ability to assemble the code, and nothing would work with the output that IDAPro generates, so I wrote my own 6800/6809 assembler that handles the format.

I added the 6800 portion for handling the Williams Sound Board rom.

I posted the source for the assembler at
