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.
