9 -- 16 pins translation.

Are you trying to adapt a PC joystick to the Apple II?

hello,

i have an 9 pins male connector, and my apple 2 joystick ports has a 9 pins output.

the line connector documentation says:

3.line connection: 9 lines total
apple --- pc
GND pin 25 as GND
PB0 pin 2 as apple side handshake in (apple -> pc);data bit 0
PB1 pin 3 apple input data bit 1
PB2 pin 4 apple input data bit 2
GC0 pin 5 as apple side handshake in (pc -> apple)
AN0 pin 15 apple output data bit 0
AN1 pin 13 apple output data bit 1
AN2 pin 12 apple output data bit 2
AN3 pin 10 apple side handshake out

to what pins ( 1-9 ) does this corresponds with?

the documentation only says what pins it corresponds with using a 16 pins connector.

thanks in advance,

digi

Are you talking about this socket?

> how else is the joystick solderd to the chip directly and not using the plug...

I think that you are on the right track. I have an old Apple II/IBM-PC joystick that came with two adaptors:

Apple II: 16-pin din connector to plug into the game port described above.

IBM-PC: 9-pin connector to plug into the game port on a PC.

There was a switch on the joystick for Apple II or IBM-PC. I assume that this switch might possibly invert and change some wiring and resistances.

I take it that what you have is a little different: You have a 9-pin IBM-PC type joystick that you want to plug into the Apple II?

This may help ya a bit into wiring an adapter

1- GAMESW1 Switch input 1 (sometimes called paddle button 1).
2- +5V total current drain from this pin must not exceed 100mA.
3- GND System ground.
4- Not Used for hand controller.
5- PDL0 hand controller input. Must be connected to a 150K ohm variable resistor connected to +5V.
6- N.C. Not connected.
7- GAMESW0 Switch input 0 (sometimes called paddle button 0).
8- PDL1 hand controller input; must be connected to a 150K ohm variable resistor connected to +5V.
9- Not used with hand controller.

This is for the 9 pin port

[2]--------------- +5V ------- 1
[7]--------------- Button 0 ("Fire") ------- 2
[5]--------------- X-axis ------- 6
[8]--------------- Y-axis ------- 10
[1]--------------- Button 1 ("Aux") ------- 3
[3]--------------- Ground ------ 8
