Summit Systems Slot Machine Support by HMS Electronics

This page has all the necessary links for servicing and repairing Summit Systems Slot Machines.  If you can't find an answer to your problem, email me with the problem and I will make every effort to get back to you with an answer. 

We only support Bally Machines that were converted by Summit Systems Inc. Please inquire about Summit Systems Slot Machine Parts. We do not support any other machine types.  If you call looking for telephone support,  I have to cover my time.  It will be necessary to obtain credit card  info to cover my time.  $30 for the first 15 minutes, $2 for each minute thereafter.
