This is an introduction to an up-and-coming technology that a small group of pinball and electronics enthusiasts are developing. A custom microcontroller that interfaces with Bally-35 MPUs and allows you to write customized rulesets, even completely re-theming games. This is the first part of a journey that I hope to take everybody on.


NOTE That this was recorded several months ago and I only recently realized I didn't make it public. So there are many other more updated videos on the progress of this project. See: pinballhelp.com for more
