I'm making major progress on restoring this Flip-A-Card and am starting the debugging phase. I've got a few other issues to track down, but I'm looking at a machine that displays TILT on power up. After hitting the reset and simulating a ball, the machine seems to work reasonably well and I can activate the tilt mechanisms to TILT it, so I know the tilt switches are working as expected. Before I spend a lot of time tracking this down, is it normal for the machine to power up in TILT?
Thanks!
