Apple Pro Keyboard (black, 2000)

The Apple Pro Keyboard was released in 2000 and replaced the Apple USB keyboard that was first released with the original iMac. The 109-key Apple Pro Keyboard had a completely transparent case with dark gray translucent keys. Notably, this keyboard removed the power key which had been present on Macintosh keyboards since 1987.

The design of the keyboard returned to the earlier extended-keyboard design last used in the Apple Extended Keyboard II. Like its predecessor, the Apple Pro Keyboard used a single support leg spanning the entire width of the keyboard to slightly elevate the back of the keyboard. When the iMac G4 was released in 2002, an Apple Pro Keyboard with the same design was released with opaque white keys.

As of 2020 Apple has released approximately 20 external keyboard designs. In general, Apple Macintosh keyboards are different from standard keyboards because they include a Command key (⌘) for shortcuts; an Option key (⌥) for entering diacritical marks and special characters; and a Help or fn (function) key. Earlier Apple keyboards also included a power key (◁), while newer keyboards include eject (⏏).

iMac G3/500 DV SE (Summer 2000, graphite)

The iMac G3/500 DV Special Edition (Summer 2000) featured a 500 MHz PowerPC 750 (G3) processor, 128 MB of RAM, a 30.0 GB Ultra ATA hard drive, a slot loading 4X DVD-ROM drive, a Harmon-Kardon designed sound system, and two FireWire 400 ports. The screen was a 15-inch CRT display.

The iMac G3/500 DV Special Edition (Summer 2000) is similar to the iMac G3/450 DV+ (Summer 2000) released at the same time, but was offered in graphite and snow rather than indigo, ruby, and sage. It was referred to as a “Special Edition” model because it had a faster processor, twice the RAM, and a larger hard drive (30.0 GB instead of 20.0 GB).

This iMac model also replaced the Apple USB Keyboard and round Apple USB Mouse with the Apple Pro Keyboard and Mouse.

iMac G3/350 (Summer 2000, indigo)

The iMac G3/350 (Summer 2000, indigo) featured a 350 MHz PowerPC 750 (G3) processor, 64 MB of RAM, a 7.0 GB Ultra ATA hard drive, a slot loading 24X CD-ROM drive, and a Harmon-Kardon designed sound system. The all-in-one case design was transparent indigo blue with a 15-inch CRT display. 

This model does not support FireWire (400) or AirPort (802.11b), even though its predecessor added support for both technologies. However, this model included a slightly larger hard drive (7.0 GB compared to 6.0 GB), a slightly better video processor, and replaced the Apple USB Keyboard and round Apple USB Mouse with the Apple Pro Keyboard and Mouse. This model sold for $200 less than the previous model at $799.

Due to the price drop, this model was purchased for many schools to update the computer labs common at the time. In my Technology Director position at the time, we upgraded at least three computer labs from tray-loading iMac to slot-loading iMac computers due to the price drop.
