Response from Jonathan: Martin,

Unfortunately JAMMAboards.com owner Tim Hensel passed away recently and the store has been closed ever since his death. At this point, we do not know if his family plans on reopening the store or not. We would ask that you keep his family in your thoughts and prayers as they go through this difficult time.

With that said, Arcadeshop also sells the Ms. Pac/Pac-Man Cabinet to JAMMA PCB Adapter your looking for but it is a little bit less convenient to hook up. Unlike the JAMMAboards.com version which had a nice place to plug in a 4-pin power supply Molex connector, the Arcadeshop adapter will require you to solder the voltage wires from your power supply to the board. In this case, it would probably be better to go with a standard 15 Amp Switching Power Supply (which you can also purchase from Arcadeshop) instead of the ATX-type computer style power supply that we use in our video. Of course, you will also need some wire to run from the power supply to the adapter board. With these items you should be able to accomplish the upgrade process we discuss in our video.

Hope that helps. Thank you for your question and good luck with your future repairs.
