I recently purchased this beige G3.

It was sold to me as being fully functional, but became my first retrobright project, as it was way too yellowed to be looked at and not be annoyed.

Here are some pics of the machine when I disassembled it completely to give it a thorough cleaning before getting to retrobrighting the plastics: (This happened within hours of me acquiring the machine!)

This gives you some idea as to how yelled this machine was.

I chose to follow this example to redrobright the machine, as I didn't want to use the submersion method, as it would have damaged the metal screening on the inside of some of the case parts:


The back panel was the first panel I started with, as it was the most yellowed:

Here's how it originally looked and here it is after 1 hour and 48 minutes:

Here's how it looked after the first redrobright session:

Now it was on to the main case plastics:

This is how they looked at the end of the day:

I took this pic when I started the last stretch of this exercise: (The final redrobright session)

This is how the machine looks now after reassembly: (It's not 100% perfect, but it's 99% better than it was, and best of all it's no longer an annoyance to look at! :) )

I've fitted the ATI Rage 128 allowing me to run a standard monitor, it also has a dual USB card fitted. I spent the whole evening yesterday figuring out how to get OS9 installed onto this thing with the ATI Rage 128 installed, as every time the OS9 installer loaded, it would run at a resolution which was out or range for my screen, so what I ended up doing was installing OS9 using the video output on the personality card and putting that through a composite to HDMI converter to get an image on my monitor.

Once OS9 was installed I changed the resolution on the ATI Rage 128 to 1280x1024, as it had been defaulting to 1600x1200!

I'm currently having one issue though in that the system detects the USB card and shows it in the system profiler, but for the life of me I can't get it to work! I also tried the Belkin card which works perfectly in my G4 Digital Audio, to no avail. it seems like I need a specific driver to make it work in this machine, as I'd like to run it with a USB keyboard and mouse as well as have mass storage support. (any help with this would be much appreciated!)

The system has a very nice floppy drive, which works, however It's missing its ZIP drive, so I'll have to source one for this machine as well as for my G3 B&W.

I had a bit of a scare this morning when I tried to swap this CPU for the 450MHz one which came out of my B&W.

I thought I’d blown the Motherboard, as the machine didn’t even give me a power light!!! Even with the original CPU and jumper block slotted!

I pulled everything, gave it a good clean, put it back together and now it works again!

The problem here is that I have no idea what happened!

But at least it now works again, so I’ll be skipping this upgrade for now!

Here's the machine's current configuration:

As with all of these projects, one thing leads to another: I currently don't have an ADB keyboard for this machine that works, but I've been able to navigate around a bit with a sticky ADB mouse that I got with the machine.
This brings me to my point: I need an ADB keyboard and mouse to complement this machine, and I need it to be as cool as possible!
So I'm going to get one of these to complement this system:

I just managed to get USB support working on my G3 Beige!

I downloaded the third file "USBSupport_BeigeG3", copied it to floppy disk using my Pentium II Overdrive system and then copied it onto my G3 beige from the floppy, uncompressed the file and then copied the two USB extensions it contained into the Extensions folder, rebooted the system, and now I have USB mouse and keyboard support!

It's still going to get its Adjustable Keyboard, but this just means that I'll be able to work on setting it up before the keyboard arrives!

It also has mass storage support, which will help significantly in setting it up!

I've spent hours installing software and games onto my new G3 Beige!
"UnStuffing" multiple disk games such as Riven took hours!

Last night I encountered a problem once I installed Riven from disk 1: while copying the contents of the data directories on discs 2 to 5 into the data directory in the Riven game directory on the system’s drive (This needs to be done in order to run it diskless), I suffered a disk error which the “disk first aid” application in OS9 couldn’t resolve, as it couldn’t even read the system disk!!!!

So I removed the hard drive and brought out my G4 Digital Audio!

I had a spare 80GB ATA drive lying around, so I repartitioned it using the G4. After completing this task, I thought, “let me try and repartition the failed disk”!

So I fitted the failed disk into the G4, booted off the OSX installation disk and ran the disk utility!

Rather than repartitioning it first go, I opted to try and repair it using the OSX disk utility.

Like magic, it was able to see the disk and carry out the repair!

I returned the “now repaired” disk to the G3 beige, and it worked!!!

I was able to successfully complete the installation of Riven before calling it a night, or morning for that matter!

Through all of this drama, I didn’t lose my OS9 setup which I had spent hours setting up!

The lesson I learned here is: don’t be too quick to try and repartition a “failed” disk!

Keep in mind that the retrobright you used is temporary, the yellow will return :( Try to add some UV blocker like the one from 303 industries.
 
Beautiful work, thank you for sharing!

When I was 16 I spent three summers of earnings on a G3 266 A/V Minitower instead of a car, to my parent's dismay. Inspired to go dig it out of my father's basement and hope it can survive the shipping back to my home.
