[Coco] Turbo DriveWire

[Boisy G. Pitre]

Aaron/Darren,

This is fantastic.  I understand Darren had to work some trickery to get this going, but the results are amazing.  Once again, DriveWire has set the standard.

It should also be noted that existing DriveWire cables will need a modification to work with Turbo DriveWire.  I believe pins 1 and 2 must be connected.  Darren, can you confirm?

Currently, DriveWire cables ship with pin 1 unconnected.
