Picked this up a couple weeks ago and decided to work on it while taking a break from the Battlezone I've been fighting with.
First thing to do was replace the installed Tron joystick with a proper Satan's Hollow joystick...
Next up was to replace the monitor. The monitor that was in it was a Commodore monitor that the previous owner put on a standard 13" monitor frame and mounted in the game. There were a couple problems with this so replacing it was a no brainer...
Next up is to add a MCR power supply adapter from ArcadeShop.com. Right now there is a switcher hacked in there but there is a hideous hum during the attract mode and you can tell the reset circuit is missed due to it not powering up consistently.
I think it's going to stay next to Gorf...
There are more pictures here...

First real game I score ~75,000 and had a ball... can't wait for my son to play and get addicted. I better sneak a few more quiet games in before I tell him it works.
