How to find your serial number in software
You can find your Mac's serial number in Apple System Profiler: Select the Apple Menu > About This Mac, then (depending on the version of OSX you are running) click the System Report button or the More Info button. This brings up System Profiler, and on the Hardware Overview that is displayed by default you should see your serial number, and be able to copy/paste it. The procedure does vary slightly between different versions of OSX.
If you can't boot your Mac
If your Mac is not working, the serial number is printed on the computer casing but the location varies. Here are the main locations of serial numbers on Apple computers.
Unibody MacBook Pro - Laser etched onto the base.
MacBook, Early MacBook Pro, PowerBook G4 - Inside the main battery bay. Remove battery to locate.
iBook (White) - Under the keyboard. To lift keyboard, pull back on the release tabs between the F-keys.
Intel iMac, iMac G5 - Underside of the foot/stand.
iMac G4, iMac G3 - Underside of the iMac.
Mac mini - On the underside of the Mac mini.

This tool is also available on its own page, with a list of all Model IDs here.

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.
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.

Difficulty 1/5 - Easy (external).

Difficulty 3 / 5 - Reasonably easy

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. The hard drive
is to the right of the case, held in upside down in a caddy with one screw.
Remove the entire caddy, this reveals four screws holding the drive. Undo the 4 holding
screws and remove the drive.
