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.

Word-11 will be tricky. I’m not aware of anyone having the media for that. ALL-IN-1 is easy, if you’re running it, you can export as a MS compatible doc. Zane

I remember using a non-DEC word processor on VAX/VMS at uni: it was either MASS-11 or WORD-11. I don't know how you would read that on anything other than VMS with the original word processor software. .MAI files are from the VMS Mail utility. The easy way to read those is to use VMS (maybe on SIMH if you don't have the hardware). There might be DECUS utilities that would pull apart VMS mail files for you and turn them into something else. This does remind me that I have a whole chunk of VMSMAIL messages myself, so perhaps I should look into something like this too! I do know that DEC was one of the first large users of MS Outlook. As part of the move away from VMSMAIL there was a conversion utility that would take your VMSMAIL files and turn them into an outlook PST (I think). From there there are tools that can turn a PST into eml files. There was a PC version of ALL-IN-1 (or maybe it was just the WPS part). That existed at the same time as the VMS ALL-IN-1 product so surely it must be able to read those files? That's assuming you can find a copy of the program. I never used it in anger, so I've no idea whether it supported exporting to other formats. Antonio -- Antonio Carlini anto...@acarlini.com

Re: What 6502 macro assembler was used for the AIM-65 Monitor ROM?
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 ).

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