>As per http://www.apple-history.com/frames/? (look up 7500 and then look at >7600.) "The PowerMac 7600 was a 7500 with a 120 Mhz 604 processor. (a new >number was given to the 7600 as a result of the new processor type) In >August 1996 >the 7600 was "speed bumped" to 132 Mhz. The 7600 was replaced in early 1997 >by the 7300. There was also, briefly, a 200 Mhz 604e 7600 Model. " (The 7500 >used the 601 processor) > >> The mobos are indistinguishable. >> >> The only things which are different are: 1) the indicia on the case (a >> snap-in part), and 3) the processor daughter card (601 on the 7500, 604 >> on the 7600).
The 7500 and 7600 mobos are identical. Installing a 604e processor daughter card in a 7500 immediately makes it a 7600. The 7300 is a completely new machine, a "dumbed down" 7600, actually, with no A-V capability at all, and a 8600/9600 powering scheme. The 7500/7600 had a 7200 powering scheme (or the 7200 had a 7500/7600 powering scheme, take your pick). The maximum speed 601 was 120 MHz. The maximum speed 604e was 225 MHz. (The maximum speed of a 604ev was 400 MHz, but none were made; 350 MHz was the fastest 604ev which was made; 250 MHz was the slowest). Remember, IBM owns and defines the PowerPC architecture. Apple and Moto are merely users of that architecture (there are many others, too, none of whom make desktop-type personal computers). -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
