Optional Pass Through Connector
The optional pass through connector assembly allows both keyboards to function. Performing
the installation above, the CoCo’s internal keyboard was not connected, thus it will be unable
to be used. This connector assembly ties both the CoCo’s keyboard and the PS/2’s keyboard
matrix chip in parallel. See figures 4 & 5 for the connector installation.
