Ok, here is what Paige would say.
Paige OWNS a Battlezone. Paige got it free, although Paige did trade a monitor (color, needed cappping) for the control panel.
Mine was/is freaking minty, had no boards, no monitor. It was NOT worth the restoration cost. I tried to replace the original monitor with a PC monitor, but you CAN'T get a 19" color tube in the place where the original monitor went (black and white vector tubes are insanely shallow, less than half the depth of a color raster tube.
Paige went ahead and installed a 15" color monitor, and then promptly got sick of the project. He listed it on ebay, buyer paid $125 for it, and ONLY WANTED the control panel, periscoper stuff, marquee, etc.
So, now I still have it, now it has a double decker control panel, which is completely INSIDE the machine, but is still in project mode.
I'll see if I can't dig up any photos.
Art Mallet can USUALLY supply ANY needed vector monitors, although he is really pricy. Otherwise you can try a wanted to buy post on the newsgroups.
You see the thing with the vector games is that a tested working monitor sells for 80 percent of the value of most games that use them.
