AIM 65 to RM 65 hardware interface

Royce Taft has a MACH-9 MMS Inc 6809 CPU Plug-in for AIM 65 and reverse engineered it.
He sent me his design to be published here.

The KIM-1 version displays on the seven segment LED displays. The AIM 65 prints it on the thermal printer.

KIM-1 version of 10 PRINT in BASIC and assember

10 PRINT CHR$(47+INT(RND(0)*2)*45);:GOTO 10

; BY MICHAEL DOORNBOS MIKE@IMAPENGUIN.COM; 2025 
; SOFT START AT $0200

; THIS PROGRAM GENERATES A RANDOM PATTERN OF SLASHES AND BACKSLASHES
; AND DISPLAYS IT ON THE KIM-1'S 7-SEGMENT DISPLAY.

; THE PATTERN SCROLLS TO THE LEFT, CREATING A CONTINUOUS EFFECT.

; A LOT OF THIS CODE IS BORROWED FROM:

AIM 65 version in BASIC

10 PRINTCHR$(47+(INT(RND(1)*2)*45));:GOTO 10

that print random ‘/’ or ‘\’

I have a page devoted to AIM 65 hardware with new photos, updated and cleaned up documents:

– Comelta S.A. Spain RAM and ROM cards
– Cubit
– Rhines and CRT2 Video
– MTU Micro Technology Unlimited expansions for the AIM 65

And some modern expansions:
SM Baker remakes of video and FDC and bus cards.

A number of interesting AIM 65 projects found on SM Baker’s github page (thanks Scott for the latest updates)

Backplanes
Designs for 2 and 3 slot backplanes. Gerbers included.

AIM-65 display adapter board

This is a display board based on the RM65 display board.
Supports up to 512KB of onboard ROM, which will be addressed into the 24KB address space starting at 0x9000. The 0xA000 range is left
empty for onboard peripherals. The four-position dipswitch controls which 32KB segment of the 512KB ROM is mapped.

Multi-banked ROM file for display board
ROM image tools

tape-rs232-c1541
Application board for tape, RS232, and Commodore 1541 AH5050.

Speech board with SP0265A

FDC based upon RM65 FDC

There is a new page on AIM 65 hardware produced by others, like video cards, dataloggers and more.

Multi-ROM adapters by Steve J.GRay

The PET/CBM MultiROM adapter is usable on the AIM 65 also. It gives a 4x DIP switch selectable choice of 16 ROMs. Handy in the B000 socket, where language ROMs are placed.
A 27512 EPROM holds the ROMs.

Kicad designs here.

Rockwell did sell KIM-1s as an OEM product around 1977. They bought the KIM-1 PCB, made in a Commodore factory and put a sticker on the right corner, covering the Commodore MOS logo and text, as you can see in the image below.

The documentation such as KIM-1 User Manual and the Circuit Poster were given a new front and back, the contents of the User Manual were 99% coming verbatim from MOS Technology/Commodore. The Programming and Hardware Manual were later (and better) versions of the MOS Technology documents, no trace of the 6501!

I can proof this, in 1978 I bought a KIM-1 from a Dutch distributor Famatra and still have it. It was a Rockwell package. Here you see photos of my Rockwell KIM-1 package labeled as Rockwell but it really is a Commodore MOS Technology product rebranded. It did not take long before Rockwell started to sell the AIM 65 as replacement and I never saw advertisements not a Databook with a Rockwell KIM-1 in it.

The Rockwell KIM-1 User Manual is scanned by me and available on the KIM-1 and MOS Technology manuals page, as are (later versions of) the Rockwell Hardware and Programming manual. I might scan these Rev 0 versions one day also.

See the page of me and my KIM-1 for my first KIM-1 and its history.

You can see the text Commodore and MOS logo shining trough underneath the Rockwell sticker. And the number SC1276 gives away it was manufactured in the Santa Clara Commdore factory.
