But I'm not certain I know which pins you're talking about. --------+-----------------------++---------+--------------------- pin # | Signal Description || Pin # | Signal Description --------+-----------------------++---------+--------------------- 1 | +5 Volts || 9 | No Connection 2 | Switch 0(Command key) || 10 | Paddle 1 3 | Switch 1(Option key) || 11 | Paddle 3 4 | Switch 2 || 12 | Annunciators 5 | Strobe output || 13 | Annunciators 6 | Paddle 0 || 14 | Annunciators 7 | Paddle 2 || 15 | Annunciators 8 | Signal ground || 16 | No Connection --------+-----------------------++---------+--------------------- I am interested in the possibility of making a splitter cable for the port but I'd need to know where I could find the parts nessasary and what the pinouts would be for each joystick. -- -MSC AIM: MSC1983MSC ICQ: 42442595 "Stand Back! I have an open Power supply and I'm not afraid to do something stupid with it!" All you need is a simple 'Y' adapter to convert the X-Y axis and buttons to the other set used by the 2nd joystick. That's only four wires different. Note that generally the player using joystick #1 will have access to joystick #2's main button. This can not be helped unless you remove that wire from the 'Y' adapter to prevent cheating. This is not recommended as you will want to use the second button on many games that are single player only and you do not want to constantly open and close your IIgs to add/remove the adapter. X axis (P0 to P2) Y axis (P1 to P3) Button0 (S0 to S1) Button1 (S1 to S2) OK, get yourself 3 appropriate connectors and solder thusly, pin to pin. I recommend that you solder a long ribbon wire to the inside connector and run it to a small circuit board on the outside of the case where you can mount the two joystick sockets. Hot glue on the solder side when thick enough makes a good insulator and helps prevent the wires form coming off. Using the 16 pin internal game connector inside your Apple II: (II, II+, IIe, IIgs) AII JS#1 JS#2 5V 1 1 1 S0 2 2 S1 3 3 2 S2 4 3 P0 6 6 P2 7 6 Ground 8 8 8 P1 10 10 P3 11 10 I'll throw in the 9 pin version of the Y adapter too, no charge. :) Using the 9 pin external joystick connector on your (IIe or IIgs) AII JS#1 JS#2 S1 1 1 7 5V 2 2 2 Ground 3 3 3 P2 4 5 P0 5 5 S2 6 1 S0 7 7 P1 8 8 P3 9 8 Note that the IIc and IIc+ can not use the Y adapter because of 2nd joystick wires are instead used for the mouse.
