The statement above as written is correct but could lead to confusion, because there are MachV cards which do not fall into the category described. So, all 300+ MHz 604e cards are Mach Vs, but not all Mach Vs are 300+ MHz. All the PPC604e cards which shipped in *Apple* machines at 250 MHz or faster used the PPC604ev, AKA Mach V. In practice, this was all of and only the cards shipped in the PowerMac 8600 Enhanced and PM 9600 Enhanced, both of which are also known as (AKA) Kansas machines. To further confuse things, there were earlier versions of both the 8600 and 9600 which were non-Kansas. So there was an 8600 and then the 8600 Enhanced. And there was a 9600 and then the 9600 Enhanced. But folks typically leave off the "enhanced" which means that you can't be too sure what someone has when they say 8600 or 9600. The Enhanced versions were the ones called Kansas, which shipped with Mach V CPU cards. All the Kansas cards ran at speeds of 250 MHz or faster (300, 350). Now you may be thinking, "Aha, it's easy. If I see a CPU card with a 604e and it is 250 MHz or faster it is a Mach V." But that's not correct. It only applies to the Apple cards. Umax, Power Computing, and some of the third party upgrade makers shipped 250 MHz 604e cards which are not Mach V cards. Hence, the qualification that it was only Apple cards at 250 MHz or higher is necessary. Jeff Walther -- SuperMacs is sponsored by <http://lowendmac.com/> and...
