1 GHz eMac (Education)

Based on the 1.25 GHz 2004 eMac, the education-only model includes a 1 GHz G4 CPU that was available either with a CD-ROM drive or no optical drive at all. The education eMac also lacks the built-in modem of the consumer model.

eMacFor connectivity, USB 2.0 replaces USB 1.1, and Bluetooth is an option. Apple also switched to Radeon 9200 graphics.

Although it has the same physical dimensions as the original iMac, the eMac is heavy – 50 pounds vs. 35-38 for the 15″ CRT iMacs.

This was the first generation of eMac to require Mac OS X. Although it supports Classic Mode in OS X , it cannot boot the Classic Mac OS directly.

IMPORTANT: The 2004 eMac was covered by the eMac Repair Extension Program for Video and Power Issues, which included problems with scrambled or distorted video, loss of video, and no power. Apple’s website includes a list of serial numbers covered by this program, although refurbished 2004 eMacs may be covered but have a different range of model numbers.
