Hahahah! I actually have one of those @266Mhz as well as a K5 @133. Boy, those where the fun days!! You could actually swap an Intel with an Amd, no problem!! Ofcource, AMD CPUs where pretty much a copy of the Intel ones... but who cares about history!!! AMD FTW!!
Ahhh..the days of taking out an Intel Pentium MMX 266MHz (fastest on offer), and installing a K6-2 500 or if you were lucky, the K6-III+ 450 @ 600MHz. The way things are going we'll soon be saying the same about...hey, hang on: where'd that Core2Duo dissapear to...? lol.
