Hey all, I am new to this retro collecting thing and recently received this joystick in an Atari 2600 lot I bought. From what I've been able to find, this seems to be a VIC-20 joystick, which apparently didn't sell too many before being discontinued due to a lawsuit from Atari. I'm looking for more information on this from people who are more familiar with the subject. Anyone here have any ideas on how rare it is? Is this something people are looking for? I noticed the joystick doesn't have much movement.. could it be locked up? Is it something I should open up and take a look at? The story itself seems really interesting, so I was looking for some more info on it. Any conversation on it would be great!
