G3 Wallstreet Side


This machine is the second generation of the PowerBook G3, and it changed to a different case design (the first G3, the "Kanga," is not featured on this website).

Available in both 12.1" and 14" screen versions, the PowerBook G3 Wallstreet is based on a 66MHz system bus, and brought desktop clock speed and CPU cache to the laptop, something the original G3 lacked.

The PowerBook Wallstreet was still a significant investment, costing around £2500 for the top of the line version. The machine switched to using faster and cheaper SODIMM memory, and had significantly better graphics with the new ATI chipset.

The machine shipped with Mac OS 8.1 installed, but will support Mac OS 9 to OS 10.2.8. 10.3 and above will not work on these machines.

How to Identify these Machines

The G3 Wallstreet can be identified by the colour of its keyboard, which in contrast to subsequent G3 PowerBooks, is black.

The Wallstreet has the older legacy Mac connectivity: an HDI-30 SCSI connection, a square port with 30 pins, and two 8 pin serial ports. The machine also has one 4 pin ADB port for keyboard or mouse connectivity and a 15 pin VGA port for an external monitor.

If you are still unsure you can contact us on 01223 833 412 or by email for confirmation. If you want to upgrade but aren't happy to install your upgrades then we can help. Simply ask our engineers for further details.

Memory Upgrades

The PowerBook G3 has two memory sockets, and can accept up to 192MB in RAM. A 128MB module can be fitted in either slot, once a 128MB stick is fitted, the second slot can only take up to 64MB.

We do not have RAM available for these Macs.

Difficulty 3 / 5 - Reasonably easy (top slot only)

Turn off the machine and remove the CD-ROM, power cable and battery.

Inside the now empty bays there are two latches which hold the keyboard in place. Push these towards the front and gently lift up the keyboard.

There is a large metal shield which is secured with two Phillips screws - undo and gently lift up the plate. This reveals the top RAM socket which can now be accessed.

The second socket is underneath, but professional installation is recommended for this. Mac Upgrades does sell RAM for installation in the bottom slot, however we cannot provide installation instructions or support.

CD/DVD/Blu-ray Drive Upgrades

The PowerBook G3 Wallstreet came equipped with a CD-ROM drive in its right drive bay. At present there are no internal CD or DVD writers which fit internally into this machine.

It is possible to use an external device with an added USB or FireWire card (FireWire is strongly recommended). Since any added card will not supply power to a device, only full-sized, mains powered devices are listed here.

This laptop is not powerful enough to burn DVDs, so no DVD-RW devices are listed here.

There are no optical drive upgrades available for these Macs

Difficulty 1/5 - Easy (external).

Install any supplied software, restart the machine and connect the new device.
