Robert, there are a number of things that can cause this problem.   
      
   If you tip a pin in the memory unit -does the machine then scan and play?   
      
   If so, then look at the contacts in the "Playrak" it's located at the left   
   rear of the machine right near the coin mech. There is a set of contacts over   
   a toothed wheel that "make" when credit is present.  there are also two relays   
   in there whose    
   contacts must be reasonably clean and operate with adequate pressure.   
      
   Though unrelated to your problem, it is very important that the mechanism be   
   properly lubricated with 20wt oil.   
      
   As you've probably noticed, the is board is pretty much dead. I suggest   
   joining these:

   These are all active and you'll get more involvement from people who know   
   these old machines.
