Anyone know what 6502 macro assembler was used for the AIM-65 Monitor
ROM, as shown in the AIM-65 Monitor Program Listing manual, document
number 29650N36L ?
Some of it's identifying features are using .BYT and .WOR (or .WORD)
directives for declaring data, and .MACRO and .ENDM directives for
declaring macros. Use of the macro directives can be seen in the
RM65-5101 Floppy Disk Controller (FDC) Module User's Manual, document
number 29801N02
There are countless 6502 assemblers available now, the exercise here
is to identify the macro assembler that was used at the time. If it is
available to run now the goal would be to run it to assemble source
code exactly in the format that it used and produce identical listing
output. (Modifying the source code to be accepted by a different
assembler to produce identical binary output is not the goal of the
exercise).
