Here is a simple 6800/6809 assembler I wrote to compile a Robotron 2084 disassembly I did in IDAPro. IDAPro outputs an asm format unusable in any assembler I am aware of, so I needed one that can handle the output format.
This assembler currently compiles my main CPU romset (6809 code) back to the original, for multiple flavors of Robotron romsets (Yellow, Blue, Fix 1987, Wave 201, and TieDie), and it compiles the Williams Sound Board sound code (6800 code) back to the original (robotron.snd below).
The asm files are not in this repo. They may be elsewhere, named CLRobotron.asm and CLRobotronSound.asm
The assembler usage is
clasmtool filename [options] where filename is the file to assemble, and options are
-o outname : assembles a total rom image to outname
-r rompath : where original roms are located for comparison
-s split path : where to put split output roms
-c : display rom checksums, needed in Robotron 2084 code at end
-t num : testing 1-4, various helps in getting code clean
-i : run in interactive loop (q to quit, ? help)
It requires System.Value.Tuple.dll from Microsoft, obtainable via nuget.
For example, to compile the asm file and compare to the original, place the roms somewhere, and execute
clasmtool clrobotron.asm -r rompath -t 4
Here are some details on the ROM sets I tested against. ROM images can be pulled from your robotron machine. Fields are
