Several NoBeige readers reported that Terrahertz International is selling iMac upgrades, which include a 266 MHz G3 processor module, 64 MB memory upgrade, and Mac OS 8.5. NoBeige staffers are betting that the processor module is just clock-chipped to 266 MHz and there is no mention of backside cache. Hmmmm… Terrahertz International can be reached at orders@thedesignation.com.
