It is possibly an in house generated assembler. It may even have been written in Forth. Most Forth assemblers are written as single pass but it is not hard to make it a multiple pass. Such an assembler could have been cobbled together in Forth in a couple weeks of one programmer. I do know that they did extensive internal work in Forth. I have a ICE product that was clearly done in Forth ( missing pods and personality floppies ).

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

I assume you've looked at RM65-dos.zip on Rich Cini's site? http://www.classiccmp.org/cini/systems.htm ----- Original Message ----- From: "Glen Slick via cctalk" <cctalk at classiccmp.org> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Sent: Friday, March 22, 2019 1:09 AM Subject: Re: What 6502 macro assembler was used for the AIM-65 Monitor ROM?

I was thinking the same thing and actually went looking for one, but the only reference I could find was to a PDP-11 cross-compiler version of one of the other languages available on the AIM. I don't remember which, PL-65 maybe. Will "He may look dumb but that's just a disguise."? -- Charlie Daniels "The names of global variables should start with? ? // "? --?https://isocpp.org

That is less than 1 year after the introduction date of the VAX-11/780. I suppose it still could have been something that ran on a VAX by then, or a PDP-11 (or PDP-10?), or some other mainframe/mini host if it wasn't self hosted on a Rockwell 6502 development system. It's really just more of a curiosity issue at this point if anyone finds a definitive answer.

(Followed by hardware, which was a 68000 exerciser board or a bare SUN-1 processor board). I'm pretty sure there was also a 68000 cross-assembler from Moto on the Amdahl, although I'm not sure whether I used it or not, might have to confirm it's output with the output from mine. IIRC the Moto programs were written in Fortran (oops, FORTRAN).

I didn't notice the link for the binary files there too. I just took a look at that. I'm not sure exactly what that is. It doesn't appear to be for the DOS firmware that would be located on the FDC Controller EPROM along with the low level FDC primitives located at $8000 - $8EFF. The manual lists the part number for the firmware ROM as A65-090.

The next question is, does anyone have a disk with directory structure and utilities?

Hi Glen Sorry for not replying right away. I've been on the road. No, I've not gotten the manual. I do have a disk controller board with my system. I'd have to look back to see what disk controller code was in the ROMs. I suspect it might just be to read the first bock of data and then expect the rest of the code to be from the disk for disk I/O. Next chance I get, I'll look to see what is there.

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 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.
