History: The G3 All-in-One built on the success of previous built-in monitor models. The AIO was the first Built-to-Order All-in-One Mac, and was available only in educational markets. It was based on the same motherboard as its big brother, the PowerMac G3 (Desktop/Mini-Tower), and had a built-in 15" monitor. The 233 MHz Configuration started for $1599 U.S., and the 266 MHz Configuration, which included video input and output, sold for several hundred dollars more.
