Since the Blue and White G3 has been on my mind, I thought it’d be fun to see what’s going on with that machine on Apple’s support site. I stumbled across an FAQ, which includes this information:
What is USB? Is it the same technology used in iMac?
The USB (Universal Serial Bus) implementation in the Power Macintosh G3 (Blue and White) is the same as iMac. USB is a standard for attaching peripheral devices to a personal computer, delivering higher performance (up to 12 megabits-per-second) than previous serial port connection methods. USB is used to connect devices such as keyboards, mice, trackballs, modems, printers, scanners, and joysticks. You can plug in and unplug USB devices without restarting the system. Maximum cable length is 5 meters. Up to 127 USB devices can be attached to the computer simultaneously.The Power Macintosh G3 system ships with two USB ports. Apple also provides a USB keyboard and USB mouse with each system. The Apple USB Keyboard includes a built-in, bus-powered hub with two additional USB ports. The Power Macintosh G3 (Blue and White) also includes an Apple keyboard extender cable that increases the length of the Apple USB Keyboard cable and gives you the option to place the system either on the desktop or on the floor.
The article then points users to this page on Apple’s site about USB:
The Universal Serial Bus (USB) combines all of the advantages of a multiplatform standard—including decreased cost, increased compatibility, and a greater number of available peripherals—with the more specific advantages of a very Apple-like blend of advanced functionality and flair.
