3100 SB Audio (250-1632)      Joystick/MIDI Port      Faxback Doc. # 3164

The joystick port on the CT1350 is identical to that on the standard PC
game control adapter or game I/O port.  The port can connect any analog
joystick with a 15-pin D-Sub connector and support all standard PC
joystick compatible software.  Remember, if your PC already has a game
card or port, either remove it or disable the game port on the CT1350
card by removing jumper JP8.  Disabling the joystick port does not affect
its use as a MIDI port.

If you need to run two joysticks, a joystick splitter Y-cable is
available.

CAUTION:  Using Y-cables obtained from other sources may not work.

MIDI KIT

The dual joystick port and MIDI port takes up only one slot in your PC
leaving room for other cards.  To access the MIDI function requires the
optional MIDI Kit.  The MIDI Kits contains a MIDI adapter with a joystick
port so you can use both a joystick and a MIDI instrument.

The MIDI Kit alone does not complete the list for a MIDI setup.  You
still need software.  The FM Intelligent Organ, bundled with this
package, supports the MIDI keyboard.  You can play the computer keyboard
as well as the MIDI keyboard.
