Hi, I was about to convert some old 6502 source code over to DASM and thought it might be cool to instead use the original tools (this is for an emulation project) if possible.
I grabbed a couple older assemblers off the net but none of the ones I tried were able to handle this particular format and set of directives. From some old doc I found it looks similar to the AMAC Atari Macro Assembler but I wasn't able to try this one.
The code is for a CP/M system that uses a 6502 as its graphics controller. It is circa 1983.
some "fingerprints":
PAGE
ORG
EQU
DB, DW, DS
HIGH / LOW pseudo ops
Hex values suffixed with 'H' vs. prefixed with '$'
The entire source file can be found at

Any other leads on what might have been used?
Thanks.
