I took a closer look at that HP1000 on ebay. The guy sent me some better pictures of the unit. Just to let everyone know here, this unit is obviously a highly modified OEM model. There are special non-HP cards in places where there aren't supposed to be any cards - even HP ones. The card cage itself is modified. Not that it's necessarily a bad thing, but I want to let folks know that the standard HP1000 operating guide may not be much help with that system. Jay West
