- Hi! there,
-
- I have an Apple joystick (the plate says: Apple IIe, IIc Model No
- A2M2002...) and I'd like to connect it to my PC clone. I'v known the pin
- layout of PC's game port and I'v figuered out the connections of X-Y
- position controller. But I'm having a hard time in understanding the
- connections of the fire buttons. Each button looks like this *** no matter
- it is pressed or not ***:
-
- bottun PIN
- another button -----1--------2----------------------------o 2 (5V DC?)
-
- 3--------4----------------------------o 1 or 7
- |
- |----------------^^^^^^----------------o 3 (GND?)
- 270 Ohm
-
-
- There is no ON/OFF response (as checked with an Ohmmter) when I
- press/release the button. I wonder if the buttons need power-on to
- function or both the buttons are bad?
-
- A joystick is nothing but I am just curious and eager to know. Can someone
- help me by e-mailing me a circuit diagram or telling me how do they work?
-
- Thanks in advance!
-
- PS: I don't know if Mac uses the same joystick and that's why I posted on
- Mac groups. forgive me if I was wrong.
