Lisy80: The Ultimate Tool for Troubleshooting Gottlieb System 80, A and B (1980-1989)
Why the Lisy80 is a revolution in the world of pinball
What the Lisy80 replaces:
The Lisy80 replaces the CPU board of your Gottlieb System80 80A 80B pinball machine, including:
- The Reset Board, often a source of problems. Originally installed to prevent the original CPUs from freezing and burning out the coils or transistors, it is often malfunctioning and causes bugs on pinball machines. With a Lisy80, it becomes completely unnecessary.
- Ground issues. There are often grounding problems on Gottlieb Sys80. Our board was designed to overcome this issue.
- The batteries that destroy your boards. The Lisy80 is a true computer, allowing you to get rid of the batteries that tend to oxidize. Even with lithium batteries, you are forced to change them at least every 5 years and lose the scores that took you years to achieve.
- The original troubleshooting modes, which were useful at the time of their release but are far from efficient today.
- The complexity of troubleshooting a pinball machine for a beginner. Troubleshooting is simplified thanks to the information feedback provided by the web interface. In a few clicks, you can find out whether the CPU detects a target dropping thanks to the switch map.


The features brought by the Lisy80
Test features
Switch status map

- In red the "Closed" switches.
- In green the "Open" switches.
For example:
- If switch 23 "Hole kicker" is red, it means the board detects that it is closed, which can be triggered by a ball or a short circuit.
- If you drop the targets on the playfield and they do not appear in red on this table, there is a strong chance that there is a contact problem at the target under the playfield.
Lamp control

At Gottlieb, most elements are controlled like lamps, including relays or coils. For example, the "Game Over" relay blocks or activates the playfield, and on the "Volcano" model, the "SAVE BALL" is controlled like a lamp.
Solenoid control

Solenoid control makes it easy to test solenoids such as the "fire pit", the "Subway" or the "Knocker" with a single click. The Lisy80 sends a pulse to avoid burning them out.
Display control

This feature lets you write whatever you want on the displays in order to test whether everything is perfectly functional.
DIP switch control

If you want to modify the game rules or the configurations originally provided by Gottlieb, this menu lets you control everything as you wish, with descriptions of the features as in the original.
Sound control

Lets you play any sound available in your pinball machine's ROM.
Other features

It is possible to update the board over the internet. In the future, we plan to offer brand-new features on the System 80, 80A and 80B, because the Lisy80 board can be connected to the internet and is capable of being used to do anything!
Why choose a Lisy80
The expert's ace
Thanks to all its features, it makes troubleshooting a pinball machine much easier. Whether you repair your pinball machine yourself or call in a repairer, this board will save you a lot of time and therefore money.
Modern electronics
Our boards are designed with the most generic components possible, derived from mass-market industry. They are therefore approved on a large scale and far less prone to failure. In the event of a failure, our components are very easy to find commercially and easily replaceable by any electronics repairer for a few euros. In addition, the Lisy80 board is a true computer, which will make it possible in the future to add any feature, although this is not mandatory.
The open source choice
Our boards are based on the open source project www.lisy.dev by Ralf Thelen, which allows the entire project to benefit from the features we develop.
