I hate to say I found a reasonably nice one in a guys basement by his coal stove for cheap. Other than being covered in the grey soot it was in reasonably good shape, cabinet is a bit beat, but the thing is mostly black so touch up seems pretty easy, the playfield is what I really care about and it appears to have had full mylar from day one.
Now if I can only get the game to work, sad no repros of the MPU are being made. The board will fully boot and show a "0" on the LED, when I press SW2 it turns to an "8" then back to "0" like it is suppose to, but the game will not go into attract mode. Nothing works, ever, from the time I turn it on, only the GI comes on and that is it. No solenoids fire, no sound of any kind, no displays.
The test point voltages on power supply are right one, all fuses are good. I am thinking a trace or two in the battery acid damage area were broken on the MPU, it did have some acid damage. I have printed out Clay's list of chips and what each leg traces to, but it takes so long to got through them all, I am about 1.5 pages into the 10 pages. I have only found one questionable one, I get continuity, but it is marginal, so I will put in a jumper on that trace. Can anyone guide me as to which chip I should be focusing on? What would let the MPU test good, but still not let anything work/go into attract mode. Am I missing something obvious that is not the MPU?
