A contribution by Michael Steil of the scan of ‘Siemens Personal Computer PC 100 Bedienungsanleitung, Ausgabe 1981/1982’
The Siemens PC 100 was a version of the 6502-based “AIM-65” SBC in a case and with slightly modified ROMs. Siemens offered a set of German-language manuals, which included translated Assembler (MOS Resident Assembler) and BASIC (Microsoft BASIC) manuals, but also a general manual (“Bedienungsanleitung”).
See the PC100 page for more information like manuals and ROM dumps.

The MTU pages have been updated.
– New are 8 documents on the MT-130 page, like DISKEX (file exchange with e.g. CP/M), Wordpic, Forth 79, later version of the Full Screen editor.
– The K-1013 Dual density floppy controller has its own page now, with new information
– The MT-130 is emulated on Mame
– MTU K-1000 power unit photos
– the MTU projects by Eduardo Casino
Not yet added are the results of the ongoing discussions on the threads on forum64.de, like multipage K-1008 displays, K-1013 replica builds, CODOS V1 and V2 dissecting.

Thanks to F.J.Kamerewerd, DL6OE, I have a photo of a EMUF 65XX with a very special CPU, the Mitsubishi M50734.
This CPU is from a family of 65C02 cores with enhancements.
Around this M50734 the EMUF M50734 is published in MC Magazine 11 1911.
See here for the information available. Photo by F.J.Kamerewerd, DL6OE
Theo Kortekaas, a member of the Dutch KIM User Club, published in the club magazine the KIM Kenner, Issue 11 and 20, a chess program for the standard unenhanced KIM-1.
The program files are from audio cassette digitized wave files from 1982. for keypad and LED display.

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.
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.

Warranty card that came with this KIM-1
Imagine a true 6530-002 and 6530-003 replacement , the RRIOTs of the KIM-1
Now with modern FPGAs you van do that: a 40 pin PDIP replacement: the reDIP RIOT is made for that purpose.
Here is the code for the reDIP to make it a 6530-002 or 6530-003:
Github with gateware for Commodore MOS 6530 RRIOT
Since the 6532 is in fact a subset of the 6530 (no ROM, more RAM), it seems not too difficult to make a 6532 replacement this way.
The reDIP RIOT is an open source FPGA board which combines the following in a DIP-40 size package:
Lattice iCE40UP5K FPGA
1Mbit FLASH
5V tolerant I/O
The reDIP RIOT provides an open source hardware platform for 6530 RRIOT / MOS 6532 RIOT replacements.
