Need help with sprint machine

Ok...

First of all,  there are no empty sockets, right ??   Looking at your pic, it's hard to tell.  The large black object toward the upper RH corner looks like there is a chip in it, but I can't tell for sure.  Actually, it must, that's the main CPU and the board would be dead if that was missing.

Carefully clean the board, compressed air or one of those dust blaster cans.  That board is a mess and something might be shorting.

Clean the edge connectors by rubbing them with an eraser until they are shiny.

For these next two steps, you'll need manual,  pdf scans are available on the net,  google for it, some searching should find you one.

Look for a "test" switch in the cab somewhere, flip it and start the machine, see if it reports any failures.

Check all your input voltages with a voltmeter.  Primarily the 5 volt dc circuits are what's needed for the game logic, those should be darn close to 5.  The AC feeds to the board and the 12vdc (if used) should be close, but don't have to be dead on.  

Beyond that, I'm going to suggest you have the board repaired by somebody familiar with game board repair.  The first pic you posted indicates you probably have a failed rom chip or bad video ram.  Since you mentioned you don't have experience fixing game boards, it's best not to try with this one.   Atari boards can be a bugger to troubleshoot.

Good luck!

You don't need to order a new connector unless that old one is damaged. If it's only dirty, clean it.

Sounds obvious, but sometimes people need to hear the obvious.
RayB:
OH and Rob, that board has two edge connections, but only the WIDE one on the left is what you need connected, and in your photo I see you HAVE the connector (it's green!). The short one on the TOP (in your photo) is meant for diagnostics. It's not supposed to be hooked up to anything in this game. It's only meant for technicians trying to troubleshoot it with a device called a "cat box".

The top edge connection was not hooked up at all. I may need a new edge connector since mine is a mess. Some of the prongs broke off and I don't think the wires are making propper connections. The person before me connected one wire directly to the board. I am starting to think it may not be worth the money to fix. Any ideas on what this game is worth?
