Lubuntu-Remix

by

If you are looking to extend the life of your G4 or G5 PowerPC machine, open source software is a valuable tool for interesting software packages that can provide better security and breath some life into our aging computers.

One of the Linux variants that is available for PowerPC Macs is Lubuntu-Remix.

You won’t find this one on the official Lubuntu pages, because it is maintained by “wicknix” over on the MacRumors forum. He provides a few different versions, including one that is based off of Ubuntu 16 and works better on G5s. The one I have been utilizing to test some things out is MacBuntu, based off of Ubuntu 12 but with some newer software packages and more modern web browser options. Oh, and a shiny little bit of Mac friendliness like a faux Dock.

As you can see from the screenshot, MacBuntu is functional and provides some nice software options right out of the box (including ArcticFox pictured above). You will need to pay attention to your boot options, as Linux on PowerPC machines often requires making some adjustments to the boot string to make the GPUs function correctly. Without doing so, the system will likely lock up. There are helpful guides in the thread, and wicknix does a great job answering questions from newbies.

In the screenshot above, I am running MacBuntu on an old Mac mini G4. It doesn’t take too long to boot into the desktop, and it is decently responsive. You can browse the web, although webpages are fairly slow to load. Using terminal is of course nice. I also enable a vnc server, so I can remotely log in and tinker with it a bit. Ultimately, it works, and it’s something nice to mess with on a machine that is old and is limited to 1GB of RAM. Keep all that in mind as you tinker with it.

The other challenge is figuring out ways to load the OS in the first place since using a CD/DVD is likely the friendliest solution, but in my case and many others, the old slot loading CD/DVD drives in these PowerPC machines have reached the end of their life. I ended up just pulling mine out, so I was able to get the G4 to boot off a flash drive. It took some trial and error though.

I won’t say that it is as pleasant to use or speedy as a Leopard or Tiger install. It certainly isn’t as fast as OS 9 (which you can install on these old G4s). But since some of the software is newer, it is a nice alternative to throw in the mix and tinker with.

When a Dead Mac IIci Is a Gift

by

My father died this month, and one of the gifts he left my brother and I with was a love for tinkering, especially on Apple hardware.

We grew up in a household when our first computer was a TRS-80 Model 4P. Yes, it was portable, in a sense, but my dad was able to upgrade the machine with a hi-res display (or one like it). We wrote stories and played games and even dived into programming. Good times. (The TRS-80 gave me my first taste for text adventure games, which are still the best.)

When the local school system where my dad worked as a counselor began to get computers, especially during a time when you could turn in receipts at local grocery stories, he was the one who was brave enough to figure them out. He brought them home, so we could try our hands at Apple II software and a beautiful little computer called a Mac Classic. We played Dark Castle on that one. So cool. (I learned years later that my friends were jealous, while it was just the norm for us.)

As time went on, my dad started taking us to surplus auctions to pick up piles of old Apple II stuff, various IBM PC equipment, and highly desired Mac gear. Some, he rebuilt and put into classrooms so his little rural Oklahoma school could give every kid access to a computer. Others, he kept to tinker or repair or find some use. A few items ended up being sold.

So, when he died, my brother and I went up on a Sunday morning to begin digging through piles of various old systems, including a couple of rare pieces that might be highly desired, that we helped him store at the old house. Like most vintage Macs, the capacitors are at the end of life. Layers of dust seeped into the motherboards, although a few of the machines ran well. I wished I could have brought more home, but I limited myself to just three or four items for the road trip back to the east coast.

One of the items was this Mac IIci. On initial inspection, it didn’t look too bad. I wasn’t able to test it, so I loaded it up, excited to see if the Daystar card and other expansion slots would make for a really speed vintage Mac to fiddle with. I got it home, plugged it in, and discovered that it wasn’t working. Opening it up more, the battery and cage fell out, and I was greeted with the horror of what happens when one of those little PRAM batteries explode. It ain’t good.

The question is – is the motherboard worth rehabbing? Should I bother replacing the caps and trying to pull more grime and corrosion off the motherboard? Will it run without a battery? If you have answers, please post them in the comments below.

Alternately, the gift my dad gave me – a passion to rehab these old machines – does it matter? Why not try to fix it up for a few bucks? If it doesn’t work, you learned something. (For starters, take out those batteries if you need to store your old computer parts.) You had some fun. You developed some skills that may come in handy down the road. (I really need to get decent at soldering things.)

So, yeah, thanks, dad, for another project.

Intel -> Arm Transition Is Official

by

I suppose I am old enough to have endured two big transitions in the Apple world. The first, of course, was Apple jumping ship from the PowerPC line of chips, ending with the G5 as its last hurrah in that space, to more competitive Intel chips. Today, at WWDC, Apple announced its next transition, promising to release the first Apple Silicone powered Macs by the end of the year.

A Mac Mini style developer’s kit is already being primed and made available to developers to take a look at what this new era will look like.

Already, we are being shown glimpses of new Apple Universal Binaries. (Blast from the past!)

I am always in a wait and see mode, but with the advances that its own chips have given it in the phone and tablet world, this makes sense for Apple. Their chips are excellent and are probably especially ideal for laptops. A MacBook with an Apple chip is going to be fast, efficient, and small, truly fanless without settling for an underpowered mobile Intel chip. It’s kind of exciting. Right now, you can mock up your own experience if you pair a decent iPad with an Apple Keyboard.

What will be especially interesting is the desktop end of it. Will someone really use a Mac desktop with an Apple chip to do their video editing? How will it stack up against the more serious and beefy options in the Intel/AMD world? Is this Apple giving up after recently redesigning the Mac Pro? Apple has committed to continue to support and develop future Intel Macs, and I could see a scenario where Apple’s ARM chips go into the consumer side of things like Mac Minis, MacBooks, and MacBook Pros but everything else remains in the Intel world. However, it’s probably unlikely. We’ll just have to see.

On the other hand, is this the end of any customizability in future Apple Silicone chip-based machines? Will we see, for example, a future Mac mini with upgradable RAM slots? I doubt it. Maybe these future Macs won’t need upgradeability, being far more efficient than current hardware. Maybe their form factors will be simpler, and their price tag a bit cheaper too. Who knows?

Once again, Apple is taking some risks, but in this case, it’s proven. They aren’t dependent on IBM to design and push the limits of its chips. They aren’t going to be tied to Intel either. Their chips are in their hands now. Of course, this could put pressure on Intel to step up and make a case for Apple to remain a customer, working hard to develop processors to fit future products. We’ll see.

Already, Mac users with long memories are wondering when their Intel Macs will be excluded from future Mac updates. Will it be a fast transition like Leopard to Snow Leopard? Or will it take a few cycles?

What a day for the Mac.

Disappearing RAM

by

Back when I gave the Snow Leopard development build a test run, I noticed something weird that I chocked up to running beta software.

My G5’s RAM was wrong, listing as 6GB when it is actually 10GB.

I didn’t think much of it and went on working on other projects.

Booting back into Leopard, I wasn’t happy to see the RAM size remained incorrect. On top of it, I ordered a cheap 2x2GB set of sticks to further boost my G5. It was time to figure out what was going on, keeping in mind that I had not messed with my RAM at all. The only thing I had done was replace the thermal paste on the CPU.

Here’s my troubleshooting process:

1 – Open up the G5 and reseat the RAM. No fix on the first go.

2 – Reset the NVRAM. No fix either.

3 – Use a tiny bit of thermal surface cleaning solution that I use on CPUs when I put fresh thermal paste on to gently clean the edges of the sticks. Again, no fix.

4 – Spray a little canned air at the empty RAM slots. Again, no fix.

4 – In frustration, I reseated the RAM with a little more firmness. All is well. For now.

My Power Mac is showing 12GB of RAM now (which is what I have in it). Another 4GB is on the way, so I will max this ancient machine out shortly. The answer is… there is no answer. Maybe this G5 is old and near death. We’ll see.

New Site Look

by

You may have noticed a few things changed around here.

In addition to a flurry of updates, I gave G5Center a face lift. The previous WordPress theme was fine, but it didn’t give me an option to make individual pages sidebar-free. GeneratePress, my current theme, does.

I chose GeneratePress because it is based on bootstrap and is fairly light. I want this website to serve owners and users of older equipment, so less giant images and simpler code is always helpful. So far, my personal tests on a Mac mini G4 and PowerMac G5 seem to bear it out that the website is usable. The only issue I have is that WordPress fusses with me when I login with TenFourFox that my browser is outdated. No surprise there.

So, let me know your feedback. Is there something I can do to make the site more accessible?
