The iMac G3/333 featured a 333 MHz PowerPC 750 (G3) processor, 32 MB of RAM, and a 6.0 GB EIDE hard drive. The screen was a 15-inch CRT display.
This iMac was offered in five different colors: lime (lime green), strawberry (pinkish-red), blueberry (bright blue), grape (purple), and tangerine (orange-yellow). The previous version of this iMac was offered in the exact same colors.
Apart from the faster 333 MHz processor, this iMac was identical to the iMac G3/266 before it.
