The Flip

A missing screw in the plate below the drop target was causing it to tilt slightly out of alignment. Replaced the screw, fixed the alignment and the ball is no longer getting stuck back there

Closed Problem: Ball still getting stuck behind drop target. I suspect that switch is intermittent too. Let's replace it when we do the others.

Replaced the two rollover switches at the back of the playfield and the one in the right orbit

Closed Problem: Rollover switch(es) in the right orbit and both pop bumper rollover switches not registering when the ball rolls over them.

Replaced the leaf switch, the drop target is stuck in the up position still (continuously) now. I think when i was re-soldering the wires to the switch i may have bent them out a little too far and they are now impeeding the mechanism from dropping.

Drop target on right ramp wasn’t coming back up after being engaged. Looked online and found someone was having a similar issue. Suggested loosening the adjustable screw, which solved the issue. If the screw is too tight, the drop target doesn’t come down low enough to actuate the leaf switch that causes the game to register that the drop target came down. Loosened the screw solved the issue

Closed Problem: Ball sometimes sticks. I think the drop target doesn't always drop.

V1.5 game code was flashed on Revenge from Mars using a laptop running a Windows 2000 virtual machine and the USB to serial cable.

After rebooting several times it appears that the game is consistently booting into the 1.5 game code without any errors.

After performing flashing game code update, machine is booting into 1.5 code consistently.

Closed Problem: Game continues to boot factory code after motherboard and PRISM card battery replacements.

In discord we decided to keep them as LEDs for now.

Closed Problem: Not sure if this should be a Problem report but: the LED lighting elements here are not original. We should decide what to do about that.

I replaced the PC motherboard battery and the PRISM card battery.

Upon cold starting the machine it booted into the updated 1.5 game code right away.

After power cycling the game it displayed the same “Bad update game code checksum” that is was showing prior to battery replacement.

After several more power cycles I saw the 1.5 code one other time, but nearly every single time the 0.80 code is what boots.

Dom and I replaced several dead LEDs with regular lamps.

We also opened up the PC located in back-box, it looked very clean. Coin cell batteries will be replaced when parts arrive in the future; this should be done prior to updating game code.
