MMC Interface
The MMC Interface lets you transfer maps and other data from the com-
puter to the MMC. It connects to the PC's parallel port to transfer data and
to the keyboard for power.
Connections
First, turn the computer off.
The keyboard "Y" cable on the MMC interface has an adapter plug on one
end. If your keyboard uses the small connectors, attach the keyboard to
the "Y" adapter cable and plug the other end of the "Y" cable into the
keyboard connector on the PC as shown below.
If your keyboard uses the large connectors, unplug the adapter from the
"Y" cable, turn it over and plug it into the small connector on the other end
of the "Y" cable. Plug the keyboard into one end of the "Y" cable and plug
the other end of the "Y" cable into the PC.
