+5, +24, -5 volts, no +12.  As long as you have a capable (i.e. if 
you're going to be handling FM, your controller has to support FM.  
If you're putting this on a PC XT, you have to have a controller 
capable of 500K data rate) controller on your PC, you're fine.  

If you're going to be using the drive in 801 (i.e. hard sectored) 
mode, that's a whole 'nother topic and usually involves a Catweasel 
or some such board on a PC.

Wiring a cable is pretty straightforward and involves matching 8" 
drive signals up with like 5.25" signals on the controller.  I 
normally wire HEAD LOAD to the corresponding MOTOR ON line on the PC, 
but I've heard of some wiring it to SELECT and SELECT to MOTOR ON.  
Your choice.
