is it possible to connect and use a sega controller or atari joystick on a pc? i know i can connect a ps2 controller via a super box or something....
As with the PS2, you will need a special device. However why don't you just get a PC controller instead? Would save you a lot of money.
I agree with Toilet. Better to get a pc type control. I only get the ones that resemble the ps2. However, there are ones that are set up just like the xbox. If you want a good one, and this is the one that I have, look into the Recoil game controllers. The cool thing about it is it has a recoil button that you hit to retract the cord to the pc and it looks JUST like the ps2 controller! ;P
I just use a PS2 joystick, the adapter is less than $10 at Radio Shack and I already have several PS2/PS1 joysticks. I prefer it to the Wingman Extreme that I was using. There is probably an adpater for the others you mentioned, though I really wouldn't want a 1 button Atari joystick for most games.
