So I thought why not start with the Sega CD since the battery has already exploded. I wanna replace it with a 20mm ML2032 coin cell holder but I can't seem to find any that have double positive terminals that are spaced 12mm apart. Any one know where I could get one?
EDIT: Looks like there's no such thing, but as long as I find a coin cell holder with double positives it shouldn't be too hard to just attach some wire to the points. I'll post pictures when I get done with it
