This is the requested conversion from an IBM joystick to an Apple joystick.
The materials required to do it is a shielded 6 wire cable to any length
desired. Also include a 15 pin sub d male and a 9 pin sub d male. Of course
you'll need a soldering iron and solder or else get the crimping kind of pins
for the sub d connectors.
Pin assignments - looking into the d

Now with the knowledge of the pin assignments the actual dirty work can begin
The layout is with respect to the 15 pin IBM connector. Pins not
mentioned on the 9 pin connector are not used. Note the jumper between pin 1
and pin 4 on the 15 pin sub d.

5------------------------->5 GND Used for sheilding and nothing alse

Once all the connections are put together put the screws to hold it
all together. A suggestion is to put a nut with a one piece screw and nut
like the one used on the Super Serial Card for the 15 pin sub d. This will
allow for the screws on the IBM joystick. BTW I will not held responsble for
any subsequent faults or failure due to the above information. To send
comments or suggestions please mail to st1dr@jetson.uh.edu.
