What's a KAR board?

Okay as you all know...or not... I have a perfectly functioning CEI Video Poker game. Just noticed a connector on the back panel that says "KAR BOARD."
What does the KAR board do?  :Scratch-Head:

Thought no one would ever ask  :propeller:
The KAR board is an amazing device from Omega (who became CEI) that I've never actually seen.
KAR stands for Keep Alive Resistor: the board is intended to lengthen the life of all those
little incandescent switch bulbs by keeping a tiny current always flowing thru them, even when off.
The current is just enough to keep the filaments from going totally cold, but not enough for them to give off visible light.
Thus, the thermal "shock" to the filament is less when it gets switched on.

Does anybody actually have one in their CEI? Or have a schemo?

Well that's the last thing I would have guessed! Interesting though... I had thought it was maybe for some kind of control/programming on the mpu. I wonder why they didn't just make that a permanent part of the machine? Cost, I'd guess on both ends. More costly to buy the machine with it, but in the long run the casino would save on bulb replacement and the subsequent down time of the machine?  :Scratch-Head:

Hola! I'm new to NLG, just bought a CEI machine that I'm trying to get up and running. It happens to have a KAR board so I thought I would post some pictures of it.

SolidSilver:
So that's what the little hummer looks like; cool!
Thanks for sharing, Jim, and welcome to the site. :clap:
Post pics of your machine, and we'll be glad to help!
