Here are the connections that you will need to convert a //e or //c joystick
for use in a //+, or vice versa.
16 pin DIP (Apple //+) connection DB-9 (//e, //c...)
1 +5v 2
2 PB0 7
3 PB1 1
6 GC0 5
8 GND 3
10 GC1 6
For joystick purposes, you can leave all the other ones unconnected.
I hope this helps!

The joystick I have is a TG products one with balance and two buttons and stick. Internally the joystick has a potentimeter with three solder joints on one side and three on the other. Then the buttons have two soder joints each with two resistors joining them. Before my joystick fell apart I remember two wires going to one side of the three connector and another two to the other. Then one wire went to each of the buttuns and one to the center point where the two resistors meet. Ineed to know which pin of the 9 pin joystick goes where.

You may already have derived the information from the previous posting, but here is a little bit of an elaborated edition on how to repair your 9 pin joystick. Trace your pins from your DB-9 connector to your joystick. Probably the best way to find which wire is which is to use an Ohm meter, and find the connection that gives you no resistance between a pin on the DB-9 and a loose wire in your joystick. Pin 1 of your DB9 should connect to Push Button 1, which, if I recall correctly is the TOP button of the TG products joystick. Pin 7 should go to the other Push Button. PB0. Pin 5 should go the Game Controller 0, which is usually the horizontal (X-axis). Pin 6 is GC1, which is usually the vertical (Y) axis. Now you have to worry about the ground and the +5. They tend to get a little tricky. The two resistors should go from the Push Buttons to ground. The +5 should touch basically "everything". Be sure not to short it to the ground, i.e. by accidentally connecting the resistor, +5, and ground to the same pushbutton terminal. the +5 should be on one terminal of the push button, and pin 5 and 7, as well as one end of the resistor should be on the other. You should run jumpers carrying the +5 and connect the two push buttons, and the variable resistors. Again, connect the +5 to one terminal, and the GC wires to another terminal. Variables resistors have 3 terminals. Always make sure that you connect one wire to the middle one. To decide which of the other two to connect it to, you will have to guess. Connect it one way, and play a game or something. If it works, you're laughing, but if things move in the opposite way, reverse the connections. By the way, +5 is on Pin 2 of the DB9, and the Ground is on pin 3. I hope that this will be enough to help you fix your joystick... --Tak ----------------------------------------------------------------------------- UUCP: {utzoo, decvax, ihnp4, cbosgd, utcsri, mnetor}!utgpu!utcdfa!a228arig ARPAnet: a228arig%cdfa.toronto.edu@relay.cs.net CSnet: a228arig%cdfa.toronto.edu BITNET: utoronto%"a228arig@cdfa.utoronto" (<- with some luck) (or better yet, mail through CSnet) == University of Toronto -- Toronto, Canada == -----------------------------------------------------------------------------
