New Description
TOEI OEM monitor used in many games. There appears to be two revisions of this board. One has extra connectors populated and a daughter board that is powered by the main board and is marked with "292NJM2". The other has no daughter board, some of the connectors are unpopulated and marked with "L292K". Aside from this difference, the boards have identical layouts for both the main chassis and the neckboard. It appears that the daughter board and extra connections are degauss related.
