Has anybody heard of a 6502
assembler running under RSX-11M?
And is there any documentation for it?

I don't know for certain, but most of those early micros had
cross-assemblers written in Fortran - and by programmers who worked hard on
making the Fortran machine independent. If this applied to the 6502 then it
probably could run on RSX.
I don't see such listed on
http://www.npsnet.com/danf/cbm/cross-development.html
however and that has a LOT of 65xx cross-assemblers
Further searching gives hints that MOS Technology did indeed
have such a Fortran-based cross-assembler, but no evidence that
anyone still possesses a copy.
