With the jump to a PowerPC G4 processor, the iMac received an entirely new form factor. Integrating a 15” LCD monitor into the computer on the end of an insanely-adjustable arm, the iMac G4 looked as light as its white finish. It was an instant hit and helped ring in the new iPod era in Apple history along with iTunes 2. This first generation iMac G4 would be the last iMac to have the ability to boot into OS 9.

The original iMac G4 shipped in a low-end configuration with a 700 MHz G4 processor, 128 MB PC133 RAM and CD-RW drive or a high-end configuration with an 800 MHz G4 processor, 256 MB PC133 RAM, DVD-ROM/CD-RW “Combo” drive and Apple Pro Speakers. Both featured a 40 GB hard disk drive and 32 MB GeForce 2 MX graphics. Airport wireless networking was optional.

This iMac G4 is the 700 MHz configuration with 256 MB RAM, 802.11b Airport card and Apple Pro Speakers. It dual boots the stock configuration of Mac OS X 10.1.2 and Mac OS 9.2.2. It was purchased from university surplus.
