moving monitor,keyboard,mouse about 8 feet; leaving computer???

OK, here's my problem......I want to move my monitor, mouse and keyboard for my old gaming Win98SE computer to another desk and give my wife her space back on her desk. I found extensions online for the monitor, mouse, keyboard and even my sound card for two speakers, but I'm having trouble figuring out the old 15-pin (8 row, 7 row) Microsoft game joystick/controller for the AudigyGamer card. Here's the thread at pcper.com:

It seems if that DB15 is the right one, then I just need to wait for it to become available again and then order everything at once. Any ideas? Thank you.
