The third part of my series on building a DOS based VectorMAME project with a ZVG card. This video includes The first steps in getting the computer in the cabinet and getting various parts of the machine running. While this is one way to do it, there are other methods that will work, probably some that work better. Revision B removes the Power Supply modification and replaces it with a capacitor mod that actually works. Any Amp can be substituted that will work. An amp from a set of PC speakers would be a great choice.
