I'm not sure; I have yet to take it apart. Are there different motherboard brandings depending on the type of computer I have?

Thanks! This has been extremely helpful. Unfortunately it appears I am stuck with the Mylar keyboard, but at least repairing or replacing the Mylar is easy to do. Thank you!

So today I bought an Atari 600 XL computer from an Exchange store and hooked it all up to my TV. It works, but upon boot-up I get a wall of = signs that will not stop typing. I am able to run the tests upon boot up just fine - memory and sound both passed. But with the keyboard test, the = key remains down and I get a long, drawn-out tone which I cannot stop. Pressing the = key many times does not free it from its permanently activated state. So before I take it apart to fix it, I looked up a repair video on someone fixing an 800XL keyboard - Before I dismantle mine and look at it, I want to know two things - 1. Is this repair process in the video identical for a 600 XL, in terms of how things are put together? 2. Has anyone else had this issue, and can it be fixed with just a simple contact cleaning? Thanks!

I chose 'other', because I'm a broke college student and can't afford no fancy pants gold build controllers! I currently only have one controller. After taking it apart and cleaning the board, I used a hole-punch to punch out circles of tinfoil and attached them to my buttons with Elmer's glue. They still work!

So my 5200 has apparently given up the ghost and just refuses to turn on. I recall the last time it functioned (about a month ago was when I played it last) it took a couple of tries to get it to turn on, but eventually it worked perfectly fine and I was able to turn it off and on with ease as I switched out games. Now all of the sudden it doesn't want to turn on at all. I have had this 5200 for a few years, and it has worked great otherwise. At the moment I don't have anything to test the power supply itself. But I'm assuming it's the switchbox. When I was trying to turn it on I examined the switchbox after several attempts and noticed it smelled like burning plastic. It wasn't strong, but you could definitely smell it if you held it up to your nose. I took it apart and everything looks good, except for the part where you plug in the actual power supply. The part where you plug the console in - which was where it smelled like burning plastic the most when I examined it - seems okay. Attached are pics of the switchbox, which I have taken out of its shell to look at. As you can see, the part where you plug the power supply into (the black thing, I don't know the name of it) seems rusty and corroded all over. Would this be my problem? Could I take it off the switchboard and clean it up, or would it be best to just buy a new part? Also, what can I use to test out my power supply to make sure that's not what's causing the issue?
