What are the differences between the final "Summer 2001" iMac G3 models?
Please note that the final "Summer 2001" iMac G3 models -- which refers to "Summer" in the "Northern Hemisphere" -- was introduced on July 18, 2001 and discontinued on January 7, 2002.
The last generation "Summer 2001" iMac G3 series -- the iMac G3/500 (Summer 2001 - I/S), iMac G3/600 (Summer 2001), and iMac G3/700 SE (Summer 2001) -- have G3 processors, a 100 MHz system bus, PC100 SDRAM, Ultra ATA hard drives, and ATI Rage 128 Ultra video processors packaged in all-in-one cases with a 15-Inch "crystal clear" CRT display.
The "Summer 2001" line is quite similar to the "Early 2001" models that these replaced, but with faster processors and "beefier" configurations. All of these models support an optional AirPort (802.11b) wireless card and have two Firewire "400" ports.
The major differences between the "Summer 2001" models are summarized below for your convenience:
