Tempest. 2 year struggle with that bastard.
New big blue, rebuilt 6100 including a fan and the lv2000 kit, rebuilt ARII, new edge connectors, board swapped, then repaired, then repaired again. Now after all that when I turn the machine on, my flipper is missing as are most of the enemies. I can see them at the bottom, but as they climb they disappear. Then there are vector lines flashing in and out around the playfield like lightning, and most of the tunnel is missing from view as well. All the while the game is playing fine but I can't see where I am on the rim in relation to the enemies.
