Powered by G4 processors running at up to 1.25GHz, with a system bus of 167 MHz, the new eMac models come with Mac OS X v.10.3 and include Apple's iLife application suite, providing iMovie, iPhoto, and iTunes as a standard software configuration. The changes include the following: · No-optical drive configuration: This computer is available in a low-cost no-optical drive configuration · Mac OS X 10.3 · Modem: except for the educational configuration, the eMac (USB 2.0) has an internal, fax modem (soft modem). The modem appears to the system as a serial port that responds to AT commands. · Bluetooth (optional): Fully integrated Bluetooth is available as a build-to-order option · 922-6201 Bluetooth board · 922-6402 Bluetooth antenna · USB 2.0 ports: This computer has three USB 2.0 ports · Revised logic boards · 661-3279 1 GHz board: EEE code QDJ or QHL. · 661-3280 1.25 GHz board: EEE code QDK or QHM · New optical drives: · 661-3281, CD-ROM, 32x · 661-3282, Combo, 32x · 661-3283, SuperDrive, 8x · New hard drives: · 661-3209, 80 GB · 661-3266, 160 GB (CTO) · Memory, 333 MHz DDR · 661-3322, 512 MB The RAM expansion modules used in the eMac (USB 2.0) computers are 184-pin SDRAM DIMMs (dual inline memory modules) that are 2.5 V, unbuffered, 8-byte, non-parity, and PC2700 compliant. The speed of the SDRAM devices must be rated at 167 MHz (7 ns) or faster. Refer to Kbase article 86718 for more information. Important: The memory expansion cards (DIMMs) must use SDRAM devices as specified above. DIMMs for previous models of eMac or DIMMs that use EDO or SGRAM devices will not work. If they are installed, the computer will beep, and the power light will flash several times when you turn on the computer. This indicates that the computer cannot find any useable RAM. · Faraday Shield · 922-6407 · Optical Plate (used on the no-optical drive configuration only) · 922-6408 2 - eMac ATI Graphics/ USB 2.0/2005 Basics Overview · Inner AirPort Door (blank, used on the no-optical drive configuration only) · 922-6406 · Heatsink with/clip · 076-1079 · Wireless
