Back to the PowerBook.

The processor speed on this PowerBook is 266 MHz. This one has 128 MB of memory. Just enough to boot and do a few other things. Supposedly you can upgrade the memory to 512 MB with two memory cards, one 256 MB on the top and one 256 MB on the bottom of the CPU card. There is some doubt as to whether this really is the case for total memory. Apple states in their specs, depending on models, that some of the PowerBook models could go up to 512 MB. I don’t know for sure on this one. See: the Apple PowerBook page for more information. User manuals can still be downloaded from the Apple website.

Over at PowerBook Medic you can download, for free, a number of legacy Apple repair manuals for taking apart and repairing many of the older Macs. These manuals are great to learn how to change a hard drive or simply add more memory.

Speaking of taking Macs apart; I think this particular PowerBook has a problem with the PRAM battery. It tends to freeze up unexpectedly.

What is the PRAM Battery for?

Your Mac has a microcontroller/memory chip which stores data that is important to its successful startup and operation. This data is maintained when you shutdown or unplug the Mac by a battery which provides power to the chip. This chip controls the Parameter RAM (PRAM), Non-volatile RAM (NVRAM), the real-time clock and Apple Desktop Bus (ADB). Also the chip sends a constant signal to the power supply, and if this signal is not within specifications, the Mac will either shutdown or freeze.

Here is another website that has information on what to do if your Mac shuts down unexpectedly and how to zap the PRAM circuit if it becomes corrupted.

Now, on to another Mac note. This particular PowerBook model came with a UH276 Macally CardBus PCMCIA to USB adapter for Mac. The CardBus PCMCIA to USB adapter for Mac is no longer manufactured but We Love Macs website has the cardbus drivers available for downloading for OS X v 10.1, OS X v 10.2, and OS 9. The We Love Macs website also has the cardbus PCMCIA driver download available for the PC.

I have a number of internal hard drives just sitting around and thought I would see if this particular Mac could read and write to an external/internal drive. What I have is a $25.00 to $35.00 universal hard drive adapter from Apricorn that is designed for serial SATA or PATA parallel IDE hard drives to USB. You simply plug the universal adapter in the drive and then the USB cable into the computer. In this case, plugged it into the cardbus PCMCIA USB pigtail.

Once I installed the drivers for the cardbus, and rebooted the PowerBook, the external harddrive showed up on the desktop. See screen shot of the desktop with external drive on the display screen monitor. Cool; I was able to format the drive, and read and write to it. This particular drive was 120 GB in storage space.

So, now I had a fresh install of the operating system, and started playing around with it. I was able to browse the web and do a number of items. However, there are many limitations with this particular machine. It was at this time, I decided to try a different direction for the PowerBook.

Ubuntu – Xubuntu Linux for Old World Macs

Ubuntu is one of the easiest Linux distros to install. I have experience installing Linux on a PC, and thought it shouldn’t be too difficult to install on a Mac PowerBook G3. Well, there is more than meets the eye when it comes to the old world Macs. First off, you don’t simply install the Linux with a click of the mouse. You can’t just put a disk in and automatically go through the installation process. No, it requires doing a few things prior to even loading Linux. For example, you have to prepare the hard drive with the proper formating and partitioning. With only 4 GB of harddrive space, there is not much room for installation. The reason is, you need to have the Mac OS 9 operating system installed first on one partition, and set aside another section of the hard drive for Linux.

After downloading and burning a boatload of CDs with lots of Ubuntu
versions and Xubuntu (which is a streamlined version of Ubuntu, designed for less memory and smaller hard drives) versions, I discovered that there were only a limited amount of the versions that could be installed. The one I had successfully installed, after a dozen attempts, was Ubuntu v 5.10 Breezy Badger. It only took me two days, working in some spare time, to get it to load. I had to learn a little bit of Linux commands along the way. I have to say, I found the Flyback Transformer website that was quite helpful for Installing Ubuntu 5.10 Breezy Badger on an Old World Powerbook G3 Wallstreet.

I also have to say, this whole experience was an exercise for learning. There are even a few typos in the install procedure that are easily overlooked which were time killers. I suggest you read the entire procedure, including the comments from beginning to the end, before you try and tackle it yourself.

Here are a few important notes to be aware of:

Make sure you format the hard drive with hfs standard formating.

Make sure the filesystem for your os9 installation is hfs standard, and not hfs extended. It appears to make a difference; and the default file format for os9 is hfs extended.

If you don’t do this to begin with; when you go to make new directories, and copy files from one location to another within the Linux OS area, you won’t be able to do it, and you won’t know why. This tripped me up for the longest time. Also, I partitioned the hard drive for 1.1 GB for OS 9 and approx. 3.0 GB set aside unformatted for Ubuntu Linux. Reason for 1.1 GB was the need for more software in the OS 9 installed side of things.

The video was a little buggy. I ended up adding this line of code to the special BootX software addon that allows you to boot either Mac OS or Ubuntu Linux.

video=atyfb:vmode:14,cmode:32

Note: That video command line is slightly different of what the Flyback Transformer website has.

Also, pay particular attention to typing details. For example the procedure calls out for copying and renaming the "initrd.gz" file to "image.ramdisk.gz." However, later on the file naming is accidentally reversed, with ramdisk first instead of image first.

Copy the “initrd.gz” file from the Breezy CD’s boot folder to the top level of the System Folder. Rename the file to “image.ramdisk.gz”.

cp boot/initrd.img hfs/System\ Folder/ramdisk.image.gz

note it should be:

cp boot/initrd.img hfs/System\ Folder/image.ramdisk.gz

Now for some additional feedback. Once I had finally figured out the installation procedure, I made another discovery that proved to be a little difficult to overcome. Remember I said the only installation that I could get to work was Ubuntu 5.10 Breezy Badger. Well, this version is no longer supported for updates, and there seemed to be no easy way of updating to a newer version of 6.06 or 7.10 Ubuntu or even Xubuntu. With that being said, I once again wiped away the harddrive and reinstalled Mac OS 9.

Additionally, I could use this internal drive as the main drive and then add on an external harddrive with the USB cable. As the prices of solid state harddrives come down, or even the price of USB drives that do not require an external power cable, it would be very easy to add on for storage capacity. I saw an 80 GB hard drive at Newegg.com for $54.00. Memory upgrades would cost somewhere between $50.00 and $120.00 to max out the memory. I could install OS X, up to version 10.2 I believe. That would add another $50.00 dollars or so to the price. Add to that a new PRAM battery for $30.00, and you can see you could put a little bit of money into this machine. This places the total somewhere around $200.00 to outfit it. Yes, you can spend less, especially if you have an old hard drive just sitting around. Also, it is important to note that this Wallstreet PowerBook had the CardBus PCMCIA card for USB. That makes it much easier to add an external hard drive. If you have to replace the internal hard drive, the costs could be significantly higher. Also, bear in mind, the hard drive for the operating system needs to be no more than 8 GB in size. So if you install a new hard drive, make sure you are less than 8 GB for the partition for the operating system. You can have more than one partition, so storage can be increased.

So, is it worth doing something with this PowerBook G3 computer? It all depends on what you want to do with it. Good luck on your quest

By-the-way, checkout the new Apple MacBook Pro. This is a truly amazing machine for business or personal use.
