Whatever you do, don't use this:

For the reasons documented here:

tl;dr: you get bit shifts and whitespace in comments, but no OS-9 support
and it'll almost certainly break on files that follow the official
Motorola syntax.  It will do 6800/1/3 though (with the same caveats).

A better approach might be to run your source through a preprocessor
that collapses it into something a proper assembler will handle.

As for bit shifts, did you consider substituting "<< 8" with "* 256",
for example?
