In chronological order of manufacture date, just like the game room:
Spanish Eyes: Probably could use flipper readjustment. Game is slightly misleveled to the left.
Totem: When it's willing to boot at all, player displays are varying shades of almost blank.
Swords of Fury: Flipper buttons are crap. Considering retrofitting a custom Fliptronics-like system into it. I already have the opto switches. Replacement side rails are too short and look stupid. One translite lamp board is missing.
Black Knight 2000: Horrible cabinet that needs a complete finishing overhaul. Horrible playfield that needs a replacement. Magna-Save is locked on (and thus disconnected).
Rollergames: Some lifting inserts but not too bad. Deep Freeze magnet is locked on (and thus disconnected). Game is slightly misleveled to the right.
Addams Family: On route. One Power magnet is locked on (and thus disconnected). Cabinet is in rough shape; previous owner repaired several joints using drywall screws. Could end up with a cab replacement in the future.
Twilight Zone: Gumball motor is dying. Some lights don't work. Bottom flippers angled lower than I'd like.
Road Show: Playfield has small particles of green tarp all over due to poorly securing the tarp while driving the game home. Otherwise, looks and plays pretty much perfect.
Undertale: Software is incomplete. Wiring might have to be completely redone from scratch before the machine will be reliable.
Wow... that's every machine I own. Pinball budget resets January 1st. It's going to be a busy 2019.
