Killer Comet / Challenger / Megatack Centuri Board Lot

Lot of four original Centuri / Game Plan arcade game circuit boards from 1980.  We believe these are used by Killer Comet, Challenger and Megatack, based on our research.  The roms are labeled "KC" which probably corresponds to Killer Comet. With that being said, they are labeled Centuri, 1980 and we believe Challenger and Megatack were licensed to Game Plan from Centuri and shared the same board system.

Listing includes two video boards, one CPU board and one sound board. They are fairly clean boards, but have been sitting for many years and probably will need some work. Sold untested and as-is.
