I've got a long-neglected old workhorse Saturn. Your basic US model 1, mfg date of April 1995 on its sticker. Still has solid A/V output even from RF. And it doesn't mind normal disc scratches at all.

Except for the battery compartment... Aside from its missing cover, the battery holder has been damaged. Jamming objects inside to hold it down is rather ugly, probably unreliable too. I'm not sure if the battery there is still good. But that wouldn't matter right now anyway.

What should I do? No idea where to get such parts. Assuming I'd be able to install them.
