Re: 2 Joysticks?

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.  :)

Note that the IIc and IIc+ can not use the Y adapter because of 2nd
joystick wires are instead used for the mouse.
