https://github.com/BallySternOS/BallySternOS https://github.com/BallySternOS/BallySternOS ballysternos is a really neat arduino project that sits on the debug header of old bally and stern mpu boards. the arduino holds the 6800 in halt from the start and re-implements game code i've seen at least two of these in the wild, one in a Bally Eight Ball running "Eight Ball Plus" code, and another in a Stern Meteor running "Meteor 2021". both add some neat super-features and game modes, the Meteor has an accompanying wav trigger board, speakers, and amp to add wav sound effects as well -- anyone who loves Meteor will appreciate (or hate) that it no longer screams your spinner value in a high pitched tones.
