Warning!

The following information is provided for users with concrete electronics knowledge and

experience. There are 5-volt pins on the joystick interface that can provide a surprising amount of

current if short circuited, causing potentially expensive and/or irreparable damage to components in the

computer, as well as information loss, and any other number of disasters. By providing the following

information, urr Sound Technologies Inc. in no way encourages general users of converter to attempt

the construction of devices for interface to the PC gameport, and is in no way liable for any damages or

loss of data as a result of the construction and/or use of any device based on the following information.

End of disclaimer

Note that there are two differences on the joystick port found on a soundcard

, such as the Gravis

Ultrasound or SoundBlaster, versus the original IBM-spec PC gameport interface – pins 12 and 15 are

assigned to midi functionality instead of the original ground and +5v designations.

You will almost always want to use the soundcard gameport pinout, unless you know otherwise.
