Black Knight making odd noise and dropping games

Do the lights blink, or totally shut off?
Restart a game, or just lose the ball?

There are actually 3 different ways it tilts.
A slam tilt just resets the machine, no fanfare to it, it reboots the whole CPU back to E800 in the code.

Ball roll and plumb bob tilts shut of the GI, plays a sound, and ends the ball.
Playfield tilt flashes the lights, plays a different sound, can't tell from the code if it ends the ball or the game.

Thank you for the in depth code knowledge. It ends the game, not just the ball. So, from what it sounds like, its a play-field tilt, possibly. And the lights blink, yes.
 
I'd check the slam tilt too, just in case.

Slam tilt switch is on the inside of the coin door, right by the hinge. It's a leaf switch with a round metal weight on it.

Playfield tilt is a similar looking switch, on the bottom of the playfield, near the outhole.
