I have my instructor's complete 1.2.6 disc, expansion pack, game controller and assortment of cables. I have no problem with purchasing if it will work. (Either I buy new or buy his and he gets newer version.)
I have been trying various routines trying to get this working most of day and all evening.[>:] I install 1.2.6 and expansion pack and then the download upgrade and try to load and get 'unable to locate cable' I have tried using 15 pin male in the joystick port, put adapter to USB on and tried that port. same reply.
I have uninstalled all several times. I get the above response before I download the upgrade. With the download installed it gives illegal operation and shuts me down.

This is what we are working with: (My computer skills are limited)
Computer: Win98SE. PC133 System Board, Pentium III 800 MHz, 10Gb avail memory, 256 RAM 60% free, built in Graphics system
*Onboard 128-bit 2d/3d 100MHz host interface AGP Graphics Accelerator. complies with AGP V2.0)
*Shared memory architecture allows a max of 64 MB main memory to act as buffer
*Supports high resolution to 1920x1200 16M colors, ut to 2048x2048 texture size and Virtual screen up to 4096x4096
*Supports hardware DVD Accelerator

1) I added Gamecommander to as a controller ID initially when I have it in joystick port, when I put it into USB port, computer recogized new item and added it as hardware, but it also added USB as a controller ID. Does program look for that name as a controller? When I select Gamecommander it shows it not connected if it is connected thru USB port.

HELP Please.

I also have a cord with a 9 pin female going to a male pin jack with two black insulators on shaft. The 9 pin has PRO printed on it. Have not figured just how it would connect to a TX.
No assistance from instructor as he is comm pilot and out of town for several days.

The 9 Pin cable must be plugged in to use it! Just plug it in .. there is a chip in there that will activate the program.

Then you can use your Commander.

P6 of manual covers attach to a TX and shows the 9 pin cord hookups. P7 5. Optional: Attaching and calibrating of GameCommander 'instructs you need to attach the Joystick at your 15 pin Gameport...... If the joystick port is my Gameport, the instructions omit what to do with cord mentioned below.

OK, Understand to use 1) On back of computer there is a port (9pin female) with a rectangle with 2 circles inside and vertical bars on ends. No idea what it means. Is this the proper location and what is it called? Or do I need to find a connector to a different port? If so which one? joystick (15 pin or usb port...?
2) Do I need an additional adapter for the male pin jack described above (same as jacks for speakers, mic, and headphones) for it to fit the 15 pin male attached to the Gamecommander?

Cords on hand:
Gamecommander 15pin male cord;
Interface cable 9pin female to 9 phono jack (for lack of proper name);
USB connector to 9 pin male

Still confused and trying.

Do you have anything on the back of the computer that has 9 pins and fits the plug that says PRO on it?

Yes, as mentioned above.

The symbol is similar to this with closure on top and bottom.

Plug your 9 pin Pro plug into it. It's called a serial port.
