Williams System 9 tester

This pinball test rig is designed to test Williams system 9 games that came out between 1984-1985 including titles such as space shuttle, Sorcerer, and Comet. It is common for this pinball test equipment to be modified to test Williams system 11 games as well (1985-1991). This modification is done by swapping out the top 2 numeric displays with alpha-numeric ones as well as swapping the display driver board and associated ribbon cables. There are a few other connectors to change as well. We have a second system 9 test rig at the shop currently we are working on converting over to system 11 and will post it once we finish it up.
