Thanks man!
UPDATE - some nimrod DID paint the background side of the mirror, my guess is to make the image stronger without the background use, maybe routed with a 60 in 1 or something, UGH. BUT with some elbow grease, goo gone product, and steel wool I am slowly restoring it (see attached). It IS a 2 way mirror and looking so cool, cant wait to finish.
I got the monitor working finally, BUT I have also retrofit a nice flat screen LCD so I can pump in similar vector games with background! Gravitar, Lunar Lander, original Asteroids, this is going to be cool. ALSO going to use it for some Atari 2600 space games, Yars Revenge will look sweet. I've retrofited a joystick through player 2 WITHOUT drilling the original control panel too, and added an on/off switch externally for black light, so I can pump in any game I want, MAME can reverse X and Y axis for mirror. PLUS I installed RGB lit buttons. This is going to be sweet.
Thanks all
