Gauntlet Legends / Midway Vegas battery

The battery is barely mentioned in the manual, but test mode will tell you if it has failed.  Just replace the IC in the picture which is on the board with the jamma connector – it’s in a socket even though it doesn’t look like it is.  Part number is M4T28-BR12SH1.
