+If you upgraded a C02 wired cabinet, the turntables are connected to the
 sub IO via a serial line that goes to another sub IO behind the front panel
 next to the 16seg display. This introduces additional latency as the input
 data needs to pass through multiple systems/PCBs until it reaches the game.
 
 This can be reduced by using a so-called "bypass" cable, that connects the
-turntables directly to the BIO2 sub IO board reducing latency significantly.
