Since I'm looking for a partner system for my home, I am just going to go thru eBay for my rquipment. There are numerous new/unused processors available, but some do not include a PC card. My understanding from the manual is that when I first power up the system, it will not initialize unless I have a PC card in the slot. So if for some reason I wind up with no PC card, do I have a useless system until I obtain one?
