Signetics also had a microassembler for the 3000 series, "Signetics Micro
Assembler", also written in FORTRAN, and not compatible with CROMIS.

If CROMIS doesn't still exist, I'd suggest AMDASM on CP/M. It's on
Bitsavers. It is a general-purpose metaassembler, not in any way
specialized for AMD parts (e.g., 2900 series).

Some time ago I started working on an AMDASM clone written in Python 3, but
it's not yet far enough along to be useful.
