What 6502 macro assembler was used for the AIM-65 Monitor ROM?

I have some Rockwell RM-65 cards which have on-board firmware. In
particular a RM65-5101E FDC Controller and a RM65-5102E CRT
Controller. It would be nice to have verified accurate machine
readable source code for the firmware on these cards. One way to get
that would be to manually type in verbatim the firmware source code
from the assembly listings in the manuals, then assemble the source
code, and then compare the resulting binary against the contents of
the EPROMs on the cards to verify a binary match.

The source code could always be reformatted to match the input syntax
of a different assembler, but from a historical documentation
perspective it would be nice if the original source code format was
preserved.

Dwight, I saw some posts from you from maybe last year where you were
looking for a manual for the RM65-1000 / RM65-1000E CPU board. Did you
ever find a copy or scan of that manual?

Does anyone have an AIM-65 DOS EPROM for the RM65-5101 / RM65-5101E
FDC Controller? From a quick look at a hex dump of the firmware EPROM
I have on my RM65-5101E FDC Controller it appears to match the low
level primitives assembly listing in the 29801 N02 manual for the card
0x886C - 0x8EFF, except the copyright string is missing at the end.
I'm not sure about the rest of the code in the FDC Controller EPROM.
It might be something specific to the system where this card was being
used, and not the standard AIM-65 DOS code. It would be nice to have a
copy of the standard AIM-65 DOS EPROM to try using the RM65-5101E FDC
Controller with an AIM-65. I have an extender board and cable to
connect an AIM-65 to a RM65 Eurocard card cage.
