The MAME emulator can do quite a good simulation of the MTU-130.
What you will need is:
Now start MAME in GUI mode:
and select MT-130 from the available systems
and start CODOS 2.0
Note that some of the disk images are corrupt. CODOS V2 works!

After researching a small lot of Rockwell AIM 65 R6500 Advanced Interactive Microcomputer, there seems to be small variations. Those deserve to be documented. First out, the keyboard variations.
Futaba FK-2054 keyboard found in serial number A43648, A43651, A43653 and A43654.
Stackpole Components 86-90-0030 keyboard found in serial number A31072.
HI-TEK 373-70125 keyboard found in serial number A11220
Futaba FK-2054 key side. Notice the straight line in Q and the plastic keyboard frame.
HI-TEK Part.No. 373-70125 key side. Notice the curly line in Q.
Stackpole Components 86-90-030 key side. Notice the curly line in Q key.
In the MC Magazine 11 1991 a special EMUF is published.
It is based upon the 6502 compatible Mitsubishi M50734 CPU. This CPU is an enhanced 65c02 in a 64 pin housing.
See the datasheet for the enhancements in instruction set.
The EMUF M50734 is a SBC in the tradition of the 65XX EMUFs.
Probably made by Elektronikladen Mikrocomputer Giesler & Danne GmbH & Co. Detmold

Q-Chess 1.0 is a chess program for the KIM-1, from around 1980. The programs requires memory expansion of 8K at $2000.
The chess board is displayed at a TVT-6 (Don Lancaster) video display alongside the KIM LED Display and Keypad.
In 1981 Fer Weber, a member of the Dutch KIM User Club published an adaptation to use the program with a (video)terminal attached to the KIM TTY interface in the Dutch magazine the KIM Kenner Issue 17.
Binaries on tape and the documentation of Q-Chess were acquired in 1981 from Fer.
In March 2025 Hans Otten translated the source of the adaptations from Dutch to English in TASM format.
This makes Q-Chess playable again! 
COMAL is an interpreted structured language. A version for the KIM-1, Junior and DIS65 is available, distributed by the KIM Gebruikers Club Nederland as KGN COMAL in the 80ties.
KIM-1 version March 2025 by Hans Otten.
KGN COMAL V1 for the KIM-1 and clones, Elektor Junior and DOS65.
A product distributed and adapted to the Junior by the KIM Gebruikers Club The Netherlands in 1985-1987.
KGN COMAL V1.0 is for the enhanced Elektor Junior.
KGN COMAL V2.1 is for the DOS65 system.
In 2015 I saved KGN COMAL 1.0 and 2.1 binaries from Junior tapes and DOS65 disks.
With DOS65 came a very compact COMAL user manual.
In the Club Magazine KIM Kenner a Amazing Maze program is found.
Based upon these binaries and documents KGN COMAL is adapted to the KIM-1.

Word and PDF versions
– scans of the original material
A recently acquired KIM-1, of the first generation (that means, No Revision, the first series!) came with a stash of documents from MOS Technology from 1976.
I have scanned those documents and they are available on this website now.
