Desktop Machine, Who Needs A Desktop Machine?! The PowerBook G3/300 Information And Performance Page



The PowerBook G3/300 represents the "high end" of Apple's most recent PowerBook lineup. The original high end machine was a 292MHz model which was offered with either a 13" or 14 " screen. With the latest round of G3 PowerBooks Apple has standardized on the 14" screen. While the current processor is a whopping 8MHz faster than its predecessor the system bus is slower, 66MHz as opposed to 83MHz on the older PowerBook/292. The result is pretty much a wash in terms of performance but I guess 300MHz sounded better than 292MHz. The hard drive is a respectable 8GB IDE which is large enough to keep you going for quite some time. There are currently two variations of the PowerBook G3/300. The original configuration comes with a DVD-ROM drive and MPEG PC card for decoding DVD movies. For roughly $500 less you can buy the 300MHz 'Book (sans DVD and MPEG card) with a 20x CD-ROM drive instead. In all other respects the two are the identical.

Like its 233MHz and 266MHz siblings the PowerBook/300 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 which host the CD/DVD drive can also take a Zip 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 welcomed 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. Unlike the PowerBook G3/292 which was limited to a 1024 x 768 resolution, the PowerBook G3/300 is capable of two other resolutions, 640 x 480 and 800 x 600. If you are viewing a DVD movie avoid these lower resolutions as the results are not great. 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
