Hey everyone, I just got an Atari 2600 (specifically 2600A). When I try to put a cartridge in it won't "lock" into place and then it pops up a bit when I let go. Is anyone familiar with the mechanism that holds the cartridge in place/if there is a way to fix this? I want to get it working but I can't even get a good contact between the console and game =( I've tried multiple cartridges and had the same problem with all of them so I am assuming it is the console that has a problem. I really appreciate any help I can get with this!
