Restoring Atari vector games from stripped cabs is a losing proposition every time.
Yes, you CAN do it.
But it costs way more than buying a good working one, AND it is just going to keep one or more other vector games from being restorable. Matter of fact, it might very well just get another working game outright killed. You see it is very, VERY common to part out working Space Duels, Black Widows, and Gravitars. Those games only go for $500-$600 in great working shape. BUT the monitor in them is worth $450. The boards are worth $100, the rest of the cab parts (panel, marquee, wiring, etc), will bring in another $125, and then they will probably be able to get $50 for the empty cabinet from somebody because Space Duel, Gravitar and Black Widow are ALWAYS mint.
Now, Vectorbeam games! Those are worth restoring from stripped cabs because they are SO HARD TO FIND.
