Hey guys,

Noticed something strange on my PP2 .. when I have Free Play dips selected, go into test mode, and move the shifter this strange glitch happens (video below).

Anybody know if this is normal? If I have it set for normal credits no glitches appear.. only in Free Play. Strange..

Thanks for any advice, Ryan
 
Just a morning bump!

Anybody else seen this behavior or can check on a dedicated PP2 board set? I assume it's normal but would really like to confirm my board set is functioning 100%.

Thanks for any help!
 
the PP2 at work didn't do that. probably an input chip flaking out. whatever run the dips run to, but I don't get why the shifter would do that. I'm curious as to the science behind this.

Atari experts, where are you?

Thanks! Just one more bump - sounds like a component might on the fritz?
 
yeah, Atari's stuff is like a convoluted mess compared to the Williams stuff I'm used to, so I can't put a finger on what exactly is doing it. since it's a dipswitch changing, I would start from there and work outward. those things also tend to get dirty contacts, which are usually worked out by turning the switches on and off a few times. for all you know it might be the vibration from the sounds causing it to flip back and forth.
