My main question is: Is it possible to actually repair those damn things once the Enter key stops responding, and the disk gets flakey.. I'm having a really hard time finding decent INTV2 controllers, 'cause no one sells them and mine are getting to be aged.. Is there a way to convert another system's controller, or flat out build my own? Maybe a keyboard hack? Anything?

and...

I have an INTV2 that had a paperclip fall in it when it was on. It turned off. It hasn't turned on since. Is there hope for him? What tools would I need, and what would I do to find and repair the damage? I'm handy with a soldering iron, but that's about as far as I've gone.

Thanks a lot, everyone.
