Paul Schroeter gave me the dump of the SYM-2 ROM and photos of the backside.

Sources of SYM-1 and SYM-2 Monitor ROMs

Many years ago Paul R.Santa-Maria (who sadly left us in 2012) gave me the listing of the source of the Monitor ROM in the SYM-1 1.1
Delivered as a listing, with the comments from the listing in the SYM-1 Reference manual and formatted close to the printed listing.

This is the heading of the listing:

SYM-1 SUPERMON AND AUDIO CASSETTE INTERFACE SOURCES
COMBINED AND CONVERTED TO TELEMARK ASSEMBLER (TASM) V3.1

0002 0000 ;
0003 0000 ;*****
0004 0000 ;***** COPYRIGHT 1979 SYNERTEK SYSTEMS CORPORATION
0005 0000 ;***** VERSION 2 4/13/79 “SY1.1”

Since the ROM of the SYM-1 1.0, 1.1 and the ROM of the SYM-2 2.0 are available:

• Converted the listing back to source format (TASM32, standard MOS format).
• Created separate source for the SYM-1 1.0 ROM, the SYM-1 1.1 ROM (the original listing) and the SYM-2 ROM.
• Typed in the audio cassette interface sources from the 1.0 reference manual.
• Changed the SYM-2 source to the different hardware (a 6532 at AC00 instead of a VIA) and other (minor) changes.
• Binary output compared to the original ROM dumps as proof the sources match the dumps.

In this archive sources of 1.0, 1.1, 2.0 listings, binary output.

I have found a second KIM-5, also in Germany of the KIM-5.

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.

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.

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.
