On this page my collection of KIM-1 software in binary format , manuals and articles, from my tapes and scanned paper archives and user contributions.
Most require an expanded KIM-1 with RAM memory above $2000, 16K recommended. Of course the Micro-KIM and the Corsham KIM Clone and the PAL-1 with memory expansion have enough horsepower to run this.
See the page for useful programs to convert binaries to papertape etc.
Not all have been tested, some use non-standard TTY I/O routines, so study, test, experiment and have fun!

KB-9 and KB-6 are the name used for the Microsoft Basic for the KIM-1. One of the 6502 family of early interpreters by the then called Micro-soft company. KB stands for KIM Basic, the 6 and 9 for the precison of digits.

MICRO-ADE assembler/editor
Updated October 2022

MICRO-ADE was the working horse for many KIM-1 users, the small and powerful assembler/editor/disassembler written by Peter Jennings, Microware. Manual and program are placed here with permission by Peter Jennings to the KIM Club (thank you Peter for this and for a great program!) |

A letter sent by Anton Muller, KIM User Club the Netherlands, to Peter Jennings, thanks Peter for the scan! |
In August 2021 I (Hans Otten) typed in the source of MICRO-Ade from the listing in the manual, the output is binary compatible with the binaries I saved from tape and are tested on the KIM-1.
The result is a source identical (in standard MOS Technology assembler format) to the listing and binary identical to the page image. I also made new high quality scan of the manual and the listing.

Q-Chess for the KIM-1
Q-Chess 1.0 is a chess program for the KIM-1, from around 1980. The programs requires a 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 and checked the binary output to the binaries saved from tape.
This makes Q-Chess playable again!

TKChess Computerschaak Theo Kortekaas for the KIM-1
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.

H14 printer and parallel keyboard routine
The Heathkit H14 printer is a simple matrix printer with a serial interface. This routine allows to use this printer via two pins at the free 6530 PIA port, see circuit diagram. Resistors are 2k2 ohm.

Printing disassembler
In 1982 I wrote/composed a program to have disassembled code on paper, with page numbers. The whole story, with the old binary and source, and a recent update can be found on this page.

Two versions (scans included): a special publication from the first days of the KIM Club in a traditional 6502 assembler and a later version for the Micro ADE assembler editor. Sources included of both versions (TASM 32),with resulting listing and papertape and Intel hex files. As close to paper original, changes due to assembler quirks.
