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

On further investigation I found this line on Rich Cini's site: I also recently received recompilable copies of the AIM monitor ROM in an A65 version and a TASM version. Here's a cached copy of A65 v1.04, the assembler used for the A65 source files. The TASM files can be compiled using the Telemark table assembler (TASM) from Squak Valley Software. My personal preference is TASM, which I use for all of my 6502- and 8080-based cross-assembly projects. Here's the link: http://www.classiccmp.org/cini/systems.htm#RWS So perhaps the A65 assembler listed there is the correct one? -Will ----------------------- I'd be surprised; I think it's more likely that they used the R6500 Macro Assembler you linked to in your previous post. There was also an R6500 Software Preparation System (SPS) but it's much more limited; looking through the manual I don't see any mention of macros and there are only 4 .OPTs vs. the 18 in the Macro Assembler. m
