jamma system, mirror inside cab, how do I change picture?

[markymarky99]

HI, I have a gorgeous SPACE INVADERS cab that will play multi jamma games.  I need to put a new monitor in it.  However, this uses a reflection from the bottom of the game up to where the screen is.  How do I change the wiring on the monitor so that when the mirror reflects the picture, it will look straight ?  thanks guys, you should see how clean this cab is !

you should be able to reverse the picture fairly easily by swapping the polarity on the yoke wires (some monitors have 2 plugs on the chassis that will reverse this for you, others have switches and others you will need to swap wires around on the yoke itself)

all in all this should not be a problem
