PC88 battery replacement
Pffew! Successfully replaced the battery inside my faithful PC88 keyboard! Found the instructions on a newsgroup. The guy was not sure if it was a CR2032 battery, I can confirm it was. I can also confirm there were a lot of screws…
Maybe some people will see some shapes in this picture, just like stars in the sky. Am I a poet or what? They kind of look like bees too.

The PC88 internal battery (CR2032) can be replaced MUCH easier than in the previous posts, with far less screw removal and no ribbon disconnection.
The top cover of the PC88 removes very easily! You can do this entire repair without even taking it off the stand.
Unscrew the screws along the back seam of the PC88 (the intersection of the top and bottom casing). Also unscrew the two rear screws that keep the side caps attached to the keyboard (2 per side, 4 total).
The top of the PC88 (where all the buttons and display are) is held in place by 2 strong clips that clip it to the side caps. While sitting at the keyboard as if playing it normally, push the metal top away from you until the top slides off the clips. If you need more wiggle room, you can unscrew a couple more of the side-cap screws (the ones on the bottom of the case) to give you more play.
The top will then slide off and you can flip it over like the hood of a car to replace your battery. No dealing with dozens of screws, disconnected ribbons or unscrewed controllers.
To put it back together, slide the top cover back onto the clips and screw everything back.
Enjoy.
