You get a big bang for the buck with this 2020 in 1 Jamma PCB. These are based on the internal boards of some of the All in One Fight Sticks available from our Asian friends. It supports power from the jamma harness, has multiple resolution modes to support the vga or hdmi outputs and the ability to add scan lines. The scan lines don't impact the game menu, unlike adding an external SLG. These boards do not support CGA.
