User manual

If you have designed modules which you previously connected to the KIM-1
expansion connector, you will find that the same signals previously present
on the KIM-1 expansion connector are also present on the KIM-4 bus expansion
connector. The wire list provided on the KIM-4 schematic (See Chapter 3)
shows the pin connections to the KIM-4 bus expansion connector. Only the
lines KO through K7, previously present on the KIM-1 application connector,
are not present on the KIM-4 bus expansion connector.
