Top Gun Chalenge dart game by Arachnid 1987

The Top Gun Challenge dart machine was made around 1987 by Arachnid.  It probably started out as a model 6000 but looks like this one was updated to the 6300 model.  The small black and white composite signal monitor needed a capacitor since someone put the last one in backwards and blew up the cap and the 7812 regulator in the power supply.  The power supply case was broke in half and had the wrong fuses.  The game board had garbage data in the NV ram causing junk on the screen, we filled the addresses from 0F0 to 800 with zeros and fixed that problem with one of our antique eprom programmers.  A lot of cleaning of connectors, re-soldering some circuits and some cabinet repairs and it's back to work for this old machine.
