When the Micro-KIM was under design a lot of thought went into every detail. One of the stumbling blocks was
the expansion port. On the KIM-1 there are two 44 pin edge connectors that are spaced far apart from one
another. While trying to keep with the original design it was determined that since the 2
nd
6530 was not
onboard, the application port was not required. Also, during the redesign, many of the signals were dropped
simply because they were just inverted signals that already existed. So, it was decided to just put the necessary
signals on the expansion connector so that it would still be possible to make an actual KIM-1 connector for
compatibility.
Looking at the signals we see that all the CPU signals are there. Address bus, Data bus, R/W, RESET, etc.
