Pull the eproms, clean their legs and re-seat them. Missile Commands usually have eprom/socket connection issues.

Looks like the 2708 eprom version. I have the same one I've never bother'd to get working...

Measure the voltage at the test point right above the edge connector and just to the left, That should be right a +5vdc. Clean entire board and edge connector and look at the top left side of the board near the roms but just a bit right. I can't see that well but looks like it can be solder or a camera flash.

Voltages and roms; Measure the voltage on the +5. Pull, clean the legs of the roms and verify...Use several reads to ensure the same results each time.
 
Thank you for all your suggestions. I'm going to have a friend out to help me soon (as I lack certain equipment to try your suggestions) If those are not the case, then does anyone here know a person who could help me for a reasonable price?

I'm hoping it doesn't come to needed outside help, but doesn't hurt to ask as well.
