With every KIM-1 came a large poster with the Circuit Diagram. The circuit stayed the same from 1975 to 1981 (when production stopped), but there were version numbers in the lower right corner. See below for what I have as Circuit poster versions.

First I show you the high quality scans of the Circuit Diagram.

Circuit Diagram versions
The size stayed the same, it came as a folded poster. Some on sturdy carton, some on thinner paper. The circuit stayed the same but there were different years and small (version) strings on the right bottom.

Only the 1977 and the Rockwell versions introduced a change: the colors were changed into all blueish.
