Unknown Exidy arcade game sound circuit board from an early Exidy game. We are not sure what game this is from, the part numbers are EXIDY OTB-1B and ASSY 77-2031. Boardset appears to be a sound board from game in the 1970s judging by its components. There are a couple of caps that are loose and a small burn at connector J4. Otherwise appears to be complete and in good condition.
