Re: 3.5 controller in the //c+

  Yeah, you can hook up a Apple 3.5 drive to the Apple //c+.  The one
of the neat things about the //c+ is (or at least mine does this) if
you don't have a disk in the interal 3.5 drive but in the external 3.5
drive.  It will boot the disk (that's Slot 5 Drive 2).  However will
not scan Slot 6 Drive 2 though. :/
