> 1.  Is this correct, and if so, where can one purchase such a cable?

	If you are just running one 5.25" drive from the controller card
	you can get on of the adapters to hook the older 5.25" drives to
	the Apple //c. They will work here to. If you want to daisy-chain
	two 5.25" drives, a few companies make custom adapters. You should
	be able to find a source in the back of Apple mags (A+, InCider, 
	Nibble)

> 2.  What are the advantages/disadvantages of this, specifically,

	Advantages:	A: Reduced power consumption and heat. Granted 
			it won't be much, but at time, every bit counts.

			B: The built in code allows for full scanning 
			of drives while booting. Your current controller 
			card won't allow this. The Slot 6 code will. 
			You probably won't notice this with a hard disk 
			in slot 7.

	Disadvantages:	A: Added cost of buying the adapter.

			B: Added expense that you Apple Disk 3.5's have
			a faulty controller board. You won't have to pay
			for the replacement controller board. Just taking 
			it to the shop, waiting for it to get fixed, and
			going back to pick it up.

	Yes.

	Unless the card only need to draw power from the slot, you'll have to
	leave the slot free.

	Your Welcome.
