PowerBook G3 Series I

code names: WallStreet

Overview

PowerBook G3 Series

The PowerBook G3 Series was designed around the same PowerPC 750 (aka G3) processor as the original PowerBook G3 - but don't confuse it with the original. Although they bear a similar name, this was a whole new computer. Available at three different speeds (233, 250, and 292 MHz) and with three different screens (it was the first PowerBook to offer 13" and 14" screens), WallStreet has a lot of options.

Note that the entry level 233 MHz version (sometimes called "MainStreet") has no level 2 cache, which significantly diminishes performance (see benchmarks for the replacement version with a cache to verify this). Because of this, the original PowerBook G3/233 earns Limited Mac label. (The later PowerBook G3/233 has a level 2 cache and is not considered limited.)

Although Apple lists the G3 Series as supporting only 192 MB of memory, many users have been able to exceed that limit, sometimes reaching a total 512 MB installed RAM.

In the field, a single battery typically yields 2.5-3 hours of use with Apple's original 49 Watt-Hour battery. Using two fresh Apple batteries could increase that, possibly boosting it into the 5-6 hour range, and NewerTech's 64 Watt-Hour NuPower battery should extend those times by 25% - close to 4 hours with one fully charged battery and 7.5 hours with two. (Running DVD movies will run your batteries down much faster.)

If you have a hard drive larger than 8 GB, you should partition is so that the first partition is under 8 GB in size (for simplicity, we suggest 7 GB). Failure to do this could eventually result in an unbootable computer, as all System files must be within the first 8 GB of drive space. These Macs can work successfully with larger drives for some time, but once a System files goes outside of the first 8 GB of space, you'll have nothing but problems.

Mac OS X

If you have a hard drive over 8 GB in size, you must partition it or you will not be able to install Mac OS X. If you are creating the partition within OS X, it must be smaller than 7.45 as reported by Disk Utility (because sometimes a GB is billion bytes and sometimes it's 1,073,741,824 bytes); we suggest simply setting it at 7 GB to avoid having to redo the whole installation if the partition ends up bigger than specified (it happens). Mac OS X must be completely within the first 8 GB of space on your hard drive or you will not be able to run OS X.

Non-Apple upgrades and peripherals (such as replacement drives and third-party memory) may cause problems when installing or booting into Mac OS X.

Be sure to read and follow Apple's "Read Before You Install" install instructions to increase the likelihood of getting OS X installed and running on the first try.

Warnings

According to Accelerate Your Mac, many WallStreet owners have reported problems with IBM/Hitachi Travelstar drives where the computer will not wake up from sleep. This is due to a magnetic sensor that responds to a magnet in the Travelstar drive. This problem does not impact other PowerBook G3 models, only WallStreet.

According to the Road Warrior, the drive controller in G3 PowerBooks is incompatible with some ATA-6/Ultra ATA-100 hard drives. When replacing the internal hard drive, you should be sure to obtain an ATA-5/Ultra ATA-66 compliant drive or an ATA-6 or ATA-7/Ultra ATA-133 drive known to work with WallStreet.

Apple's DVD drive for WallStreet supports five region switches, and this number is tracked in PRAM. Resetting the PRAM will clear the switch counter and let you start all over. (Resetting the PRAM may change other computer settings.) To reset the PRAM:

  1. With the computer off, press Fn-Shift-Ctrl-Power.
  2. Startup with extensions off (hold down the Shift key during startup).
  3. Restart the computer with extensions enabled.
