PowerBook G3/266 Information And Performance Page


The PowerBook G3/266 represents the new "mid-range" of Apple's PowerBook lineup. The original mid-range machine was a 250MHz model which was offered with different screen sizes. With the latest round of G3 PowerBooks Apple has standardized on the 14" screen. While the current processor is 16MHz faster than its predecessor the system bus is slower, 66MHz as opposed to 83MHz on the older PowerBook/250. The result is pretty much a wash in terms of performance. The hard drive is 4GB which in my mind should be considered the minimum. Owners of the PowerBook/233 will find their 2GB drives quickly filling up with today's bloated apps.

Like its 233MHz and 300MHz siblings the PowerBook/266 offers great built in connectivity options. The built in 10Base-T Ethernet connector offers a 10Mbps transfer rate, handy for plugging to the school or office network. For the home user there is an internal 56k modem with support for both flex and the v.90 standard. Last and I would guess least utilized is the infrared port offering 4Mbps wireless networking. The two hot-swappable side bays allow you to plug in two batteries for up to 7 hours use. The same bays can also take a Zip, CD/DVD-ROM or floppy drive. The floppy drive is not standard on this machine but is available as an add on.

The 14" active matrix (TFT) screen is the largest Apple has put on a PowerBook to date and has been welcome by those who need the real estate and reviled by others who complained that it contributes to this machine's overall bulk. Powering that screen is a ATI RAGE LT PRO graphics controller with 4MB SGRAM. On the backside of the PowerBook you will find both S-video and VGA connectors. This is handy for connecting to projection systems or an external monitor. The 4MB of SGRAM will support millions of colors on a 20" monitor.
