A program to let the KIM-1 play music. Store notes and its pitch in memory and listen to it.

Published in the Byte Book of Computer Music, 1979. Written by Peter H. Myers.

The listing is converted to MOS Technology standard assembler source. The resulting code compared to the publsihed code.

From 1977 to 1986 I was heavily involved in the Dutch magazine Radio Bulletin. The magazine started in the time of the then new radio long before I was born!

I started writing about my interest in electronic since 1970. And in 1977 the magazine (Dick de Boer!) introduced me to the KIM-1, and that enhanced my joy with electronics with computing.
At the university in these days electronics and computer science also came together.

We have published many articles around the KIM-1. Alas in Dutch and only on paper. Published on this website, see the Radio Bulletin pages.

Many of the articles deserve a wider public, the KIM-1 and its clones are used by a broad international public.
So I started a new project: translate the articles to English and make the software available in assembler and binary format.

A board that serves as a calculator accessible via a parallel 8 bit port, e.g. from a KIM-1. Send commands and read the calculated results.
Made by Artisan Electronics in 1977.

Acquired August 2026, as built in a KIM-1 with KIMSI system.
Page updated September 2026 with scans and KIM-1 source of the original manual and brochure.

My KIMSI

I acquired a KIMSI in August 2026. It was build into a plexiglas/aluminium case, with a KIM-1 (Rev G) and a ‘microcalculator board’. I took the system apart, no room to store the big ugly thing.

With a scan of manuals by Gerben Voort, and a third photo of a cassette with KB-9, time to refresh the KB-9 pages.

Thanks Gerben Voort
