I have created a Gottlieb System1/80 MPU Test Bench suite. This is a series of components that enable you to test the functionality of the MPU in a Gottlieb System 1, 80, 80A or 80B. There are four components 1. Power Supply, 2. Switch Matrix Emulator, 3. Output Emulator and 4. Display Emulator. The MPU can be removed from the machine and all 4 components can simulate a running machine. Or the MPU can be left in the machine and connected to the original power supply, but the 2. Switch Matrix Emulator, 3. Output Emulator and 4. Display Emulator components can be attached to the MPU to test it functionality and confirm if the problem is with the MPU or further down the line in the driver board, wiring harness, connectors, displays, controlled lights.
Here is a video of the components in use.
Each component includes the board connectors to both System 1 and System 80, ribbon cables to connect to the components, and in some cases a power cable to provide 5V to a component.
The Switch Matrix, Output and Display Emulator components have been tested with original Gottlieb MPU's, Flippp! PI-1/X4 All-in-One and NiWumpf Mark II boards, but theoretically should work with any System1, 80, 80A, or 80B MPU.
1. Power Supply - $215 CAD
2. Switch Matrix Emulator - $325 CAD
3. Output Emulator - $270 CAD
4. Display Emulator - $245 CAD
All Four components - $950 CAD(That is over $100 savings)
PM if interested or you have additional questions.
General Conditions:
1. Do not plug in and unplug components while the power is on. Turn the power off, then adjust connections as necessary.
2. Items are sold as is. Using the components not for their intended purpose may destroy them.
3. The Power Supply only provides +5V and -12V to power the MPU and the other components of the test bench. It will not power the original displays, GI lights, 24V DC or AC components or the controlled lights and solenoids connected through the driver board. Don't bother trying to replace the transformers and power supply board with this component. It won't work!
