special test fixture - pinball

Folks, Just picked up a Gottlieb test fixture for, I believe, System 1 games. It is a black box with LED displays, an array of switches, and a harness coming out the back. I have little documentation. One of the Sys 1 repair manuals gives some info -- but very little. It mentions a test rom that goes with this device. Anyone else see one of these? Use one? Any info appreciated.
