KIM-1 manuals and MOS Technology documents

On this page manuals, most English, some German and other MOS Technology documents

PDFs from all over the internet, archive.org,.thanks for that!
From https://www.retro-commodore.eu/2021/02/14/kim-1-manuals/ come the high quality scans!
Most are own scans and many hours of correcting scans to higher and cleaner quality.



KIM-1 User Manual

Four version are known to exist, a First Edition January 1976, a Second Edition March 1976 Revision 6500-15A, a Second Edition 6500-15B August 1976, and a Rockwell version Rev 1 1977.
There may have been a 6500-15C on which the Rockwell version is based. From 15A to 15B the difference is in a changed description of the 6530 timer. In the Rockwell version the keypad change of SST switch to the left is documented.
A German version is also known.
