For a while now I have been battling a dying 2.6Ghz dual core computer, but due to laziness and budget I just let it ride. At first it would occasionally crash in games, then it got to where it would crash during routine activities. After a year of this it would nail 105 degrees C in like 20 seconds and that is where the drama starts!

I threw my 2ghz “electronics” computer into my main machine’s case and used that for a few months. It’s motherboard had suffered from every electrolytic capacitor on it being puffy, but it has worked fine for nearly 5 years. I was surprised by the sound of what ended up being 2 caps blowing off of the geforce 7600 video card. In shock and excitement I removed the blown caps, slapped her back in and got another 4 months out of it before 2 more capacitors blew and took out a voltage regulator (and who knows what else with it).

Only armed with the craptop, I was stuck in a pickle! Then a co-worker came up to me and said “hey man you want this mac I only want its zip drive”. Well of course, going bonkers without my avrgcc, datasheets, and calculators, I took on the 14 year old Apple Power Macintosh 9600/300 as my bench machine, and I will now show you how I turned it from a novelty relic to a daily useful machine after the break.

So the machine I bought for the price of removing its zip drive is a 1997 powermac 9600 with a 300Mhz 604e motoroloa power pc cpu, stock 64 megs and a 8 meg non accelerated video card. These sold for 4,200 bucks new.

This one however was part of an AVID system and came to me loaded with every PCI slot filled with video gear, SCSI2, and 256 megs of ram in 8 out of 12 slots (32 meg sticks). It still had its *bitchy Rocket128 8 meg video card, and luckily a Targa2000 card with VGA output.

The cards, while impressive, are practically useless. Even if I had the dongles required to run avid stuff its mid 90′s technology that eats great amounts of power. All of these double board full length heaters were removed except for the Targa2000 card because of its VGA output. I don’t have a Macintosh monitor or adapter. Regarding the Targa2000 video card, its a fine card for the era, but a card made in this century would be awesome. With this video, mac os works, 8.x is snappy but a little limited. 9 is a dog 9.2 is better but its nothing impressive, any generic pci svga card could do the same, and so video became issue #1.

Video is kind of tricky for mac, it has to have its own rom, and its 2x as large as a standard pc rom (512Kbit vs 1024Kbit), So the first thing to do is find out what cards were available as “mac editions”.

Looking at The Mac Elite Software Downloads will give you an idea of what you can use. I have a power pc machine and would like to use an original rom, so that reduces my list down to the first table. The other tables include some roms for intel based machines, reduced (in attempt to fit the large mac rom on a smaller pc rom chip) and modified which are not really supported cards, so good luck.

To install these roms you pretty much need an x86 IBM compatible machine to use the rom flash software, and your card is going to need to have that 1mbit rom. This posed a problem cause at this moment all my pc’s with pci slots are toast, and the one card I have that might work is a 9250 with a pc rom, and the only mac side updater I could find still available for download was for OSX and this mac by nature will not go past 9.04.

Moving on I started reading about the radeon 7000. It is a pretty darn fast card for this machine, I could find mac os9 rom updates and drivers for it, and you can get the PC versions all day for cheap! Traditionally people would go on a hunt for a couple brands of cards that offered both PC and Mac versions and just never changed to the smaller rom for PC use. Those cards dried up pretty quick and if you see one now its going to cost an arm and leg (a 10 year old mac edition card used is like 40 bucks new around 100!).

During my search for software (ATI mac drivers went bye bye when AMD came in) I ran across an old site where dude grabbed any old pc 7000 and cut off the rom with a pocket knife and soldered a larger one in its place using a stove and a flathead screwdriver. He then proceeded to put it in his pc for the old 2 flash process but wondered if that was even needed. In fact no it isn’t! You can put a radeon7000 with a correct size blank rom in a mac and it will update it just fine.

I got online and instantly found a pc-pci version 7000 with 64 megs of ram brand new for 14.99 with free shipping. Once the card arrived I checked its rom and found it to be a nothing special 512Kbit 25×512 SPI eeprom that everyone has made at one point or another. I then dashed off to digikey and found a 25LC1024 made by microchip that would fit on the pads. Once that arrived I tried my best to do a professional job removing the chip, and yep a guy with a stove and a flathead had no problem, but I hosed the ground pad (doh!) … its nothing a little bit of 30 guage cant fix.

At this time I have a 15$ card with a 6$ (including mail) chip sitting on it and no bios. We need to correct that. First and foremost you need at least system 9.While I was waiting for all that shipping to happen I started upgrading my OS. The machine came with OS8.1? and I had a OS9.04 on a CD, which is the max this machine will take without some fiddling. MacOS9.04 is dreadfully slow and every other mac application you try complains about wanting 9.1 or 9.2(the last version of classic OS). Thankfully some people have sat down and cracked this problem in a program called OS9 helper. Using this program and the update disk images (US English available from apple, but I found a set for the international crowd too) you’re just a hop skip and jump away from 9.22 and the latest ATI drivers for a 7000 and much more!

Now we are ready to finish up that ATI card, insert the card into a unused slot, I wont remove the working video card yet. Then I fired up the mac and downloaded R7000-ROM-208.hqx and ati-retail-9-2-2-jan2005.hqx. Decoded and extracted both, ran the rom updater first. This will bring up a little ui asking if you want to update. It should only take a few moments to flash the blank rom and when it says that it is good. I am now ready to remove the old Targa2000 card and install the drivers.

This R7000 makes a HUGE difference in classic mac OS, where as before you could almost watch the Targa card draw windows, and Classilla (a mozilla browser for mac os9) was scrolling web pages about as my 386 would, I am now in a land of accelerated 2D and 3D graphics, Classilla is pretty useable and the computer plays a pretty mean game of Quake3 Arena @1024×768 all options cranked, but the issue is OS9.22 is very old in computer terms, software support is long gone and its still pretty slow just from its age. Besides what if I want to program my avr’s? Or get to a datasheet that is buried behind some java script? Really for this thing to be useable it needs a modern OS, something light but easy and can run on a Power PC cpu, with a ton of tools and programs, something Like Debian PPC…

I downloaded the newest version of Debian PPC as a 200 meg small CD. There are full cd’s and DVD’s but this one gets what you want off the net so its more practical for me. In order to boot linux on what is called a “Old world Mac” you need a bootloader and a place to install your distro. The main bootloader that works on these old machines is called bootX (linux). It is old and unsupported but works like a charm. The down side to it is you need to at least partially boot into OS9 first, so yeah, you have to keep OS9 around, even if its a tiny install.

As far as a place to install my copy of linux, I have a 9.2 gig SCSI (all the drives are SCSI in this old of a mac) that came out of a PC. Unfortunately, yes macs are a pain in the butt about hard drive’s too, and require that they also have a apple driver loaded onto them before the machine can use it. In the past you needed to use tools like “Hard Disk Toolkit”, which were commercial packages, that do just an OK job. Luckily people have patched apples own drive tools so you can initialize partition and format any drive. These tools do not like my install of OS9.22, so in order to use them, I had to use an OS8 boot disk.

I don’t need to partition and format the drive that linux is going on, but it does need its driver “updated” and initialized, which spatters data onto some special partitions so the computer knows what the heck you’re talking about later when you’re asking it to access the drive. In my situation the linux partitioner would not even see the drive until it been initialized.

I have a boot loader, and I have a decent enough disk to put linux on without killing my OS9 fun drive, so lets get this CD spinning! I extracted the bootX bootloader onto my desktop. Inside the folder is the application, a folder for linux kernels, and a system extension so when you’re done you can set it up where you dont have to go all the way to the OS9 desktop first before starting linux. I put the Debian CD into the drive and copied off the vmlinux and initrd from the install\powerpc folder to the bootX linux kernels folder. Start up bootX and point the kernel selection to the vmlinux off of the Debian PPC linux disk, and then point it to use the initrd ram disk also from the CD and click linux.

Sometimes if the CD was not in the machine at boot it will try and lock up. Just reboot and try again. Otherwise you should be greeted by the usual linux text chatter, then eventually launched into a basic text based installer. Simply follow the menus for the most part. When you arrive at the partitioning section it does not really matter how you partition the disk, just keep in mind to not wipe your OS9 partition or any partitions from the Apple disk drivers. So any option except use entire disk is probably safe. Also at this time it is wise to write down where the different linux partitions are, I have a boot partition at /dev/sdb7 and a root partiton at /dev/sdb8, though really I should have just stuck it all in one partition as the boot partition does not really do anything.

This is the trickiest part of the install. Debian will try to install another bootloader. You might get lucky and it might work. I have tried on a half dozen machines over the years and I have not gotten it to work, and it did not work this time either. That is fine just ignore it. The trick is to get the now customized linux kernel and ramdisk from my boot partition to my mac OS partition. Most tutorials on installing Debian on a “old world” machine say “just mount it and copy”, some even suggest using a apple prodos partition but never mention how to mount it … This install of Debian had no clue what a HFS+ disk was and I tried a dozen different ways to get it mounted or copied over. In the end the final part I needed for my main desktop computer had made it in the mail so I just gave up, used a PC SCSI card and linux on my PC to copy the 2 files off of the drive and just emailed it to myself on the mac.

Now that I have the boot files for my machine I just point bootX to use those, tell it where my root drive is, and within a few moments I am sitting at a nice little login prompt. A few apt-get installs later I was starting to build up my software. I had chosen, in the installer, to just give me a basic command line machine, if I had chosen “gui desktop” then I would have been loaded down with GNOME and a bunch of stuff I did not want or need on this machine, so I choose to install it myself. I ended up with xorg as a display server and XFCE as a desktop manager. Overall its pretty darn snappy for a 14 year old computer if you let an application or webpage load before messing with it, and over the month or so I have been using it near daily I have been happy and impressed with its performance.

Here is a short video of it coming up from a cold boot, into OS9 then into bootX, then into console linux into XFCE, which loads up a gecko browser, pdf reader, task manager, IDE, terminal and file manager along with all the desktop stuff in a reasonable amount of time. Sure its not going to break any speed records, but if you had to be stranded with this computer you would live quite comfortably. As far as its retro appeal goes, this machine is able to boot as low as macOS7 so you can get a ton of retro ware running on it, and was one of the very last models that was able to read and write Apple’s funky 800k DD floppy disks which is invaluable for my mac SE. The fact that I was able to keep it around as a cool old mac to poke around with and make it something that can be productive in my electronics work with near daily use makes this machine worth the hassle and the zip drive.

A new beta build of VirtualBox, Sun’s Oracle’s free x86 virtualization software, makes it possible to run Mac OS X as a guest operating system…no shenanigans or flaming hoops to jump through, just pop in the $30 retail Snow Leopard upgrade disc and go. This had previously only been possible with some awkward Hackintosh-style maneuvering, or using recent editions of commercial virtualization products.

At this early stage, performance is fairly sluggish, the screen size is fixed and there’s no sound support, but the OS otherwise appears to run feature-complete (including networking and USB). Hopefully future builds will ramp up to the level of functionality and performance that VirtualBox provides for other guest operating systems.

Installation tip: when you come to the step prompting for a target disk for installation (which will likely show no available volumes), run Disk Utility from the “Utilities” menu, format the virtual disk image you created when setting up the VM (Mac OS Extended, Journaled), then exit Disk Utility to return to the OS X installer. You can then select the newly-formatted virtual disk and proceed with installation.

Yo dawg, we heard you liked macs. [Charles] got sick of his Mac mini looking nice and pretty and decided to cram it into an old beige box. This old beige box just happened to be an old Apple II disk drive, so we guess that gives it some more street cred. The original disk drive sold in 1978 for $500. Man times have changed.

Wired Gadget Lab has taken down a video made by [Brian X. Chen] in which he gives a brief overview and demonstration of how to install OSX on an MSI Wind netbook. This apparently didn’t sit well with Apple, who contacted Wired and complained; Wired agreed and removed the video. Frankly, we’re disappointed with Wired’s response. While they were technically posting content which is questionable at best—in the video, Brian mentions that this is illegal and that it would be a good idea to have a retail copy of OSX on hand, but then goes on to point out that you can also download the hacked operating system off The Pirate Bay, Isohunt, etc—the video in and of itself wasn’t illegal, and thus Wired comes off as susceptible to what amounts to bullying by Apple. We’re all about creativity and innovation, and stifling that innovative spirit has never worked well in the long run.

Fortunately, if you’re feeling like you’ve missed out on the video, don’t despair: Gizmodo has posted the video on their website for you to view and enjoy.

[Matthew] sent in this slick project where he made a Mac pro Ultra Mini. He received a MacBook that had been killed by water. He took it apart, re-soldered some connections and was able to get enough of it working to be a decent multimedia machine for his tv. To make it look nicer, he found an external drive case that looks like a tiny Mac Pro. After a little bit of grinding, cutting, and zip tying he managed to get all the pieces inside the case.  We’re always happy to see hardware salvaged, and  to see it transformed to a fantastic looking useful machine is a bonus. Good job [Matthew].

Calling this an incremental update, they note that the changes seem to be additions and improvements rather than a total rebuild of the original platform. They get into the nitty gritty, discussing not only the layout and structure, but even the importance of each chip manufacturer.

Some of the improvements are obvious, like 3G. Others include the battery not being permanently attached, and the headphone jack being flush mounted. Most of the changes were in who manufactured each chip.

[via TUAW]

In short, they hit the following points:

• The case feels thinner than it is.
• The shape of the case makes it wobble on a hard surface.
• Call quality is greatly improved.
• Speeds are greatly increased.
• Battery life is underwhelming.

They seem positive in their conclusion, we’ll have to wait and see how they feel after a little more time with it.
