How to Install a Lisy80 CPU Board (Step-by-Step Video Guide)
Installing a Lisy80 board in place of the original CPU board brings a Gottlieb System 80, 80A, or 80B pinball machine back to life — and it's simpler than it looks. The video below walks through the install step by step; here's a written recap you can follow at your own pace.
Before You Start
Your Lisy80 ships pre-configured for your specific game — there's no programming required. Just grab a screwdriver and always work with the machine powered off and unplugged. Take a photo of the head/backbox wiring before disconnecting anything — it's the best reference when you reassemble.
Installation Steps
- Disconnect the connectors from the original CPU board (note their positions carefully).
- Remove the old CPU board from its mounting.
- Position the Lisy80 in the original location, matching the original orientation.
- Reconnect the connectors one at a time, in the correct direction (never force a connector).
Power-On and Diagnostics
Plug in and power on the machine: the Lisy80 boots straight into the game. You can then connect to its built-in web server from a phone or PC to test lamps, solenoids, switches, and displays — ideal for confirming everything works correctly after installation.
