Has someone fried their system yet using that port?

VCC is a direct connection to the OI power. You could use this pin to provide the operator interface with a power supply (connect a 9v battery to pins 1 and 8). You can also use this pin to *get* power from the operator interface (to power LCDs or the similar).

The reason IFI doesn't want people messing with this pin is because it is a direct connection to voltage and could fry the OI if you're not careful. That said, we've never ruined an OI -- one time we shorted some of the wrong pins on the competition port and it started going crazy but a power cycle fixed that problem.
