Evening guys,

My SeaWolf has started exhibiting a problem where, when started from a cold state, will run fine for 20 to 30 minutes at which point it freezes up (doesn't reset, the screen just freezes with whatever is on there at that particular moment). I've definitely never worked on anything this old but I know the board set is used throughout various midway games. Anyone have any thoughts on where to start?
