Multimedia Board  (250-1090)       Joystick/MIDI       Faxback Doc. # 2439

Note: The audio adapter joystick ports operated identically to those on the
      standard PC game control adapter (or game I/O port) and use Tandy
      compatible joysticks.

┌──────────────────────────────┐
│Disabling the Joystick Ports: │
└──────────────────────────────┘
If your computer already has a joystick port (or game I/O expansion board),
remove the joystick port and use Joystick Ports A and B on the audio
adapter. Use the mini-din adapter (26-0284) to connect the Tandy joysticks.

If you wish to use another joystick port, you must disable the joystick 
port on the audio adapter to prevent a port conflict. To disable the 
joystick port, remove Jumper JP10 (GAMESDIS) on the audio adapter.

┌────────────────────────────────────────┐
│MIDI Interface and MIDI Adapter Cables: │
└────────────────────────────────────────┘
The MIDI interface of the audio adapter is the standard recommended by the 
International MIDI Association.

Two MIDI cables are provided. Plug the 6-pin mini-din into the audio 
adapter.

Plug the MIDI cable end marked MIDI-OUT into the MIDI-IN connector on the
MIDI instrument. Plug the MIDI-IN end of the cable into the MIDI-OUT on the
MIDI instrument.

To connect more MIDI instruments, you can use the MIDI-THRU of the MIDI 
instruments to daisy chain the instruments.

Note: MIDI software is required to take full advantage of your MPC audio
      system.
