I expect it was their Macro Assembler running on one of the systems shown at the bottom of
the page here:

At the expense of being boo-ed for this, could the original Rockwell
stuff perhaps have been assembled using a mainframe/mini-hosted
cross-assembler?
I'm aware of several situations where this was the case.
The date in the AIM-65 Monitor Program Listing header block in the
source code is Aug 22, 1978. That is less than 1 year after the
introduction date of the VAX-11/780. I suppose it still could have
been something that ran on a VAX by then, or a PDP-11 (or PDP-10?), or
some other mainframe/mini host if it wasn't self hosted on a Rockwell
6502 development system.
It's really just more of a curiosity issue at this point if anyone
finds a definitive answer.
