Re: Rulings for modifying joysticks in 2007?

Thanks for all the info...

I took apart a PSX controller and am planning on buying a couple cheap joysticks and using the cables off of them.
Then I will solder the joystick cables directly onto the joystick pots and switches on the PSX controller PCB totally
bypassing the circuitry on the board. (I need to keep the PCB attached as it provide the mechanical structural
support for these switches and joystick) .

A couple other things I am curious about that some of you fellow hackers might know the answer to, are as follows:

1). Does anyone have a wiring diagram of the supplied GC-1000FR joysticks?
I could rip one apart and ohm it out to check but thought I would ask here first... I am mostly wondering if the
small joystick on the top of the joystick handle is connected to anything or not and what each of the buttons
are connected to...

2). Does anyone have any schematics or technical information regarding the OI or RC units?
I am wondering if each port is set up as a PC joy stick port which will support two joysticks and four buttons.

Also, I need to know if the Digital I/O lines on the RC unit have the internal pullups enabled, because I want to
hang a switch or two on these (digital I/O lines) to switch between 1 joystick mode or two joystick mode.
(for test purposes only) This way I can set it up in the code to read the switch which will allow the operators
to get a feel for each without me having to download code for each scenario.

Thanks in advance for any valuable info.
