Yes, this is definitely true for the Intel P5 parts. Haven't checked prices lately, but about a year ago most places were charging $100-$200 *more* for the slave CPU (P5-90), just because they were more "rare". >Now I'm wondering - if I wanted to use the K5 in the same application >for reasons of cost, would I be screwed?

Sorry, don't know about the K5, but you *would* have to have different parts to fulfill the master/slave roles on a motherboard designed for Intel 586's... Gary
