Classic Macintoshes, Part I

Wherein Chris acquired a 20th Anniversary Mac and G4 Cube in one day

An original G4 Cube with monitor, Apple Pro keyboard, and speakers. The full set!

I won't go into too much detail around how I acquired these, but they were part of a collection and they were far below resale. These were acquired to be part of a more permanent home collection.

Power Mac G4 Cube Delivers G4 Performance in an Eight Inch Cube

Apple, 2000 https://www.apple.com/newsroom/2000/07/19Apple-Introduces-Revolutionary/

At the Macworld Expo in July 2000, Apple revealed what might be its most interesting computer form factor: the G4 Cube. Aimed at pro users and oozing with power (for its time), the G4 Cube required no cooling fan, allowed for quick-swapping of components via a lift-out design, and was a true design statement, preceding even the iconic 2001 iPod. Starting at $1,799 ($3,000 in 2022 dollars), the Cube was relatively expensive - but have pro users with deep pockets ever complained?

When I first laid eyes on the Cube in person, I was rushed back to my childhood days, and to memories of a G4 Cube on my father's workplace desk. Even as a child, it was a marvel, a curiosity, a "black box" of technology I'm still impressed with. I knew I had to have it. Luckily enough, the collector I was purchasing from had the foresight to complete the set; the Cube came with the beautiful black Pro keyboard and mouse, spherical speakers, and 16-inch CRT (!!) Studio Display. I was overjoyed when I got home and powered it on - another throwback to interfaces, colors, and applications (hello, Sherlock) I thought I had forgotten. Nostalgia plays a huge part in Mac collecting, and this was a prime example.

The G4 Cube in use

Powering up the G4 Cube was an experience all its own, too; the familiar Apple chime, a loading bar I hadn't seen in 15 years, and applications lost to history. Everything worked, which was nothing short of a miracle. Not much else to say here, really.

Now to the main event, one of the rarest and most sought-after Macs I've ever had the pleasure of seeing and owning: the Twentieth Anniversary Macintosh. Speaking of unique designs... Built to celebrate the twentieth anniversary of the Macintosh computer and starting at an eye-watering $9,999 (later $1,999), this special edition was made to be collected. I'd assume most were turned on, used, abused, and eventually lost to the ages, but there are a few out there, and I was ecstatic to have even seen (and owned) one.

Tucked away in a corner, the seller acting on behalf of the collector had no real idea what this computer meant, or how rare it was. To be fair, until I got home and did more research, I just thought it was unique. It was, and it still is. Unopened versions of this computer and its peripherals still go for close to $20,000 on eBay. Wild!

The 20th Anniversary Mac in use

The 20AM's form factor was odd in and of itself, as was its keyboard/mouse setup and subwoofer (yep, that's what that monolith is). While this sparkling example now lives with another collector, it was another instance of "wow, how far we've come". The 20AM was also running Mac OS 9, like the Cube, and while I usually "start fresh" and wipe the hard drive of computers I collect first thing, I knew how special this was, and was not about to ruin a very clean time capsule. I left it alone, excited for the next owner to behold Mac OS 9 and a plethora of very poorly-aged Adobe design products.

I was lucky to find not just the computer and subwoofer, but the Apple remote, keyboard-mouse combo, and original manual for this Mac. A real score would've been to have found the original boxes too, which were a statement to say the least.

The 20th Anniversary Mac boxes. Hell of a find, if you come across a set, even an empty set.

To think that Apple will not make a computer that looks this interesting ever again - even a special edition, at that - is a hard pill to swallow. The Cube and 20AM, alongside the color spectrum iMacs, were an era of design that was so appropriate for the time, and while it's difficult to say: unique designs like this are likely to remain few and far between.

If anything, we can appreciate and marvel at what Apple was able to do before bean-counters and mass-production were so prevalent - not to say that Apple's Trash Can Mac Pro, current Mac Pro, and Studio Display aren't striking.

Finally, let's take a quick walk down a different memory lane, where Apple made a foray into portable computers early on in the company's history. Enter the Macintosh Portable: with its own carrying case, removable battery, and clicky keyboard that would make even the PCMR perk up, this thing was, well, massive. Unwieldy. Heavy. Remember track balls?

The Macintosh Portable, with not one but TWO SPACEBARS!

This was also a computer that came with the aforementioned Cube and 20AM (aka TAM). I could never manage to get it (or its massive 2GB hard drive) to boot properly due to a screen and/or battery issue, but before it was sent on its way, it was yet another cool nostalgia piece.

Unfortunately, you can't keep all the cool Macs, every time, unless you've got deep pockets, and this was one of those times when fiscal sense prevailed. I hope its new owner has a charger.

Zombie Power Mac G5

History of the Power Mac

Back in 2003, Apple's Power Mac G5 was a dual-core monster; with a dual 2.0GHz processor and up to 8GB of 400MHz DDR RAM, it pales in comparison to any Apple computer on sale today, but remains one of the greats in Apple's storied portfolio of consumer design successes.

Building on the success of the then-recent Power Mac G4 and G4 Cube, Apple decided it was time to further simplify their pro-sumer lineup with a brand-new design in 2003, with the announcement of the Power Mac G5 tower. As design head Jony Ive stated in an interview regarding the G5: "We wanted to get rid of anything other than what was absolutely essential," and that they absolutely did.

I've long admired the Power Mac design, which persisted from the days of PowerPC (1994 - 2005) until Apple's transition to Intel processors (2006), all the way up to the "trash can" redesign in 2013. I stumbled across a well-priced storage unit purchase a seller didn't know much about, and decided to jump on a "COVID project", which ended up being simpler than I expected.

This Particular Power Mac

This Mac's model identifiers are as follows:

  • Model PowerMac 7,2
  • Sold as M9032LL/A
  • Apple Device ID A1047 (EMC 1969)
  • Serial number XB346600FNVS

And its specifications after the build was complete:

  • Dual-core PowerPC G5 processors running at 2.0GHz
  • 1.5GB 400MHz PC3200 DDR SDRAM
  • Apple AirPort Extreme 802.11G Wifi card
  • AMD Radeon 9600 Pro graphics card with 64MB of VRAM
  • 160GB SATA 1.5Gbps Hard Drive
  • 4X DVD/CD SuperDrive
  • Lots of ports, like Firewire 400/800, optical audio in/out, and Ethernet
  • A special DisplayPort which provided power and video signal

The Full Disassembly

When I picked this up from a random stranger's garage, I had no idea what to expect. "How dusty is this thing," I wondered, "and how much money am I actually going to be willing to invest to get a computer of legal driving age to turn on? The answers were "extremely" and "about $50".

Heavy and unwieldy as it was, I managed to get the Power Mac home in one piece, and popped open the side panel to reveal something that looked like a scene from the movie "Dune".

Any sandworms in there? Beetlejuice?

Not to be deterred from the $80 I sunk into the tower and its very dated 20-inch 1680x1050 monitor, I began the process of disassembly by removing the plastic cover - which (fun fact) is required for air to flow properly through the case.

The first step was to remove the fan module immediately to the left of the dual G5 processors, indicated by the small rectangular handle. Simply pulling firmly on the module removes it; note the connector slides directly into and out of its port on the motherboard, requiring no additional unclasping.

Mostly disassembled, and not quite clean.

To the top left of the fan module I just removed was a single fan and speaker module, which provided airflow to the graphics card(s) and acted as the single built-in audio source on the tower. This fan module sits in the left-most horizontal divot in the center of the tower.

Next, I removed that upper fan module by depressing the clip and sliding it towards myself, out of the tower. This required a bit of force. This module has a wired and clipped connection to the motherboard, which requires using a small screwdriver and minimal force to free.

With most of the major bits and bobs out of the case, I removed the RAM modules, which are pretty obvious but directly below the single fan assembly in four horizontal rows. When inserting RAM back in upon reassembly, be sure to use matched pairs (equal MB/GB sizes) starting in slots 2 and 3, with 1 being the top-most and 4 being the bottom-most slot.

On the top right of the case, you'll find the hard drive bays, one of which in this case was occupied by a still-spinning OEM hard drive. To remove this, I flipped the "A" tab clockwise until it was at the 12:00 position, slid the hard drive towards the case opening, and disconnected the power/data cables prior to fully removing it from the case.

Shown: the four RAM slots, from left to right, 4-3-2-1. Top right: AirPort Extreme slot and antenna connector.

Below the hard drive bays is a set of expansion slots, one of which was occupied by a graphics card. To remove the graphics card, I removed the single screw near the right edge of the case, and gently wiggled the card free from its horizontal connector.

To remove the SuperDrive, I rotated the two grey tabs clockwise 90 degrees, and slid the drive free from the case. Note there are also cables attached here, which will need to be disconnected prior to removal.

Now came the tough part: removing the processors. First you've got the G5 processor covers, a cosmetic detail I'm happy Apple added, but be aware the clips are extremely delicate. I broke 3 of the four clips on each after all was said and done.

I would highly recommend laying the Power Mac on its side (largest flat side, with the Apple logo) prior to removing the processors. Using a long (6 inch) Phillips screwdriver extender and a nice grippy screwdriver handle, I removed the four screws on each processor, down the top and bottom channels. Note the screws are the ones attached to the motherboard posts, on the thickest metal parts of the processor/heatsink assemblies.

Once I removed four screws from the bottom processor (easier to do that one first), it was easy to gently pull the processor directly towards myself, out of the case. If this proves difficult, there may be an additional small screw at the bottom left of the lower processor. Also note the processor pins are located on the motherboard, and are easily bent. Be careful if you attempt this yourself!

I wanted to disassemble the processors at this point due to the massive amounts of dust, and in order to clean and re-apply thermal paste. This was easy enough once the processors were removed: only four hex screws keep the processor attached to the massive heatsink. There are also two small clips and adhesive on the back side of the heatsink, which needed to be detached in order to take this circuit board off.

The inner four hex screws keep the processor attached to the heatsink. The two posts on the underside here helped line up the processors and pins when I moved them back into the tower.

The final fan assembly was on the far right against the back of the case, and was removed by freeing the clips near the case opening, after the processors were removed.

So what was left? "Oh crap," I thought, "the power supply." Not a difficult item to remove, though it takes up the entirety of the bottom of the interior: just two screws on the plate covering the power supply inside the tower, and voila! I was ready to remove the three large cable clips on the bottom of the motherboard. These are heavy-duty cables and clips, so I recommend taking your time to see how and where these sit when removing the power supply.

The left connectors are below the RAM slots are black, and the last on the far right is white/clear. In this photo, the right-most fan is still installed.

Once the two screws and power cables are free, removing the plate covering the power supply required a bit of creative twisting, but was more difficult to get back in than out.

To remove the power supply unit, remove the four screws on the underside of the tower, re-orient the tower standing up, then tilt the power supply away from you and pull it out of the case. Be aware of the cables you just disconnected - they caused me a bit of trouble.

Finally, I was finished! Not really, though... hours of high-pressure air, non-static microfiber rags, a new PRAM battery, and plenty of patience later, I was actually ready to reassemble. I followed the steps above backwards, and it wasn't too bad of a reassembly process.

Once the power cable arrived a few days later, I was ready to press the power button and hope to God (!) all my effort was not in vain!

IT LIVES!!

Thankfully, it booted as expected, and after wiping the hard drive of the previous owners' files (lots of pirated content and acid jazz concert recordings) I was in nostalgia heaven. Sherlock! Old Finder! The Aqua interface! What a ride.

Final Thoughts and Tips

My last little project on this computer was the AirPort Extreme antenna: a part which anywhere will cost you $40 because it's a special T-shaped connector that was made for the Power Mac line. I couldn't find a suitable replacement anywhere on Amazon, so I opted for a solution another user suggested on Apple's support forums: a large safety pin.

Yep, it worked!

This particular model didn't have a Bluetooth card, but a Logitech keyboard with wireless USB adapter did well enough for typing when needed post-boot.

Final thought: you should be pretty handy if you attempt this yourself, but it's not a whole lot more than screws and silicon. Worst case, you have a pretty paperweight, or you can sell it to a PC builder. Apparently these cases work well with specific motherboards in PC builds due to the post configuration and the case's general timeless attractiveness.

Thanks for reading!

Thanks to EveryMac's Power Mac G5 page, Mac Parts Depot, and Other World Computing for the parts and details! This thread on iFixit also helped, despite it being a teardown for a water-cooled Power Mac.
