The problem with Apple II slots is that they are "hardwired" and not smart.
Each card has its own page of memory for a driver, and it isn't relocatable
(at least not very easy to be relocated without tricks)  This is in contrast
to, say, an IBM, where they use things like DIP switches to locate the device
driver.

Phantom slots is where a card can somehow (I really don't know how this works)
locate its driver (or fool the machine into going to it) at those pages of
memory.  

This "absoluteness" is the reason why there are "traditional" places to put
cards (the 5.25 drive into slot 6, the 80 column card in slot 3, etc).
Sounds like you may have a problem, Jeremy if you can't find a hard drive with
phantom slot assigning...

(now if those rumors about a GS+...nah)
