I had the same problem. As I was porting to a different mini I had to write a new assembler. As you have undoubtedly seen, early ‘as’ was written in assembler and not so easy to use as a base. Hence I used Richard’s Miller’s AS for the Interdata as a base (available on Tuhs):

Later I discovered that the TUHS archive has source code for the original ‘as’ rewritten in C, a work by Roger Jaeger:

Maybe adding a listing module to this version of ‘as’ is another possible route.
