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.

 Thanks,
 Mitch
