In this video work, continues on a newly-acquired game, 1987 Bally “Escape from the Lost World” – a late-model 6803 MPU game that instead of mounting a remote battery pack or memory capacitor, I’m going to show you how simple it is to install a 2032 lithium coin cell holder on the motherboard and use a cheap coin cell battery instead. This is such an easy fix that you don’t even have to remove the board from the game (if you’re careful and the board doesn’t need cleaning).
