Bally Midway MCR PC Power Supply Conversion Kit

Power supply kit for MCR arcade games (Tron, Spy Hunter, Tapper, Discs of Tron, Satan's Hollow, etc) that appears to be designed for swapping in a computer (PC) power supply in place of the original linear power supply.  We found this board in a bin of spare kits from our game restoration days.  Item is labeled "Midway 90412 Power Supply Adapter, Copyright 2009 Mark Spaeth".  We recall buying a couple of these days back then for game restorations.

Item is brand new, never used.  We do not have any installation instructions, but it appears to accept a PC power supply and the two large amp connectors for power output.
