Ok, that's it - no more Macs! Well, certainly no more Mac desktops till I move to a bigger place. :D

This was yet another find courtesy of the local classifieds. It's the PowerMac 4,4 1Ghz model with ATI graphics, USB1.1, CDRW, 640MB RAM and a 60GB HDD. I paid £25 GBP for it and the seller very kindly delivered it to me for free. Unusually, the keyboard and mouse were also included - my only other Mac desktop that came with those was my first Sawtooth.

Apple certainly made an extremely tough nut to crack for the educational market! It's built like a tank and seems almost impervious to any damage from accidents or outright sabotage by malicious kids. Taking this into consideration, I think that "T-34" is a pretty apt nickname for this computer - and kudos if you understand the historical reference and joke behind that choice. :) Although the CRT isn't a Trinitron or a DiamondMax, imho it still displays a pretty decent image with vibrant colours.

The owner had left their iTunes library and a audio sample library on the computer: both of which I've backed up and intend to enjoy. ;) As you can see, their account was not in the best of shape with core software missing from the dock and the Applications folder. In this situation, I would ordinarily reformat and reinstall from scratch but this option wasn't available to me (for reasons I shall elaborate on later.)

An easy solution was to create a new account, sign into that one and then erase the owner's account but it took a bit of effort to uninstall and fully purge the dreaded Norton Anti-Virus from the computer, however with some persistence and research, I succeeded. ;)

Issues: the eMac appears to have been well and truly locked down - I cannot access Open Firmware, FireWire Target Disk Mode or the boot options. From a cold/warm start, the computer ignores all keypresses in this regard. Presumably someone didn't want unauthorised people poking around and altering anything. Is it possible to undo this?

Try this: Shut down and remove a ram stick. Boot, reset PRAM (3x). Shut down. Put the ram stick back and then boot as normal.
 
What happens if you set the nvram to boot open firmware at boot? In Terminal:

nvram auto-boot?=false
sudo reboot

You forgot to add sudo to the first line. ;)

It worked! With every reboot the computer automatically entered Open Firmware:

That's a useful trick to have for when you need to test USB Linux installers. :)

Try this: Shut down and remove a ram stick. Boot, reset PRAM (3x). Shut down. Put the ram stick back and then boot as normal.

It took a few attempts with removing the RAM modules (in different sequences) and I also replaced the dead PRAM battery whilst I was at it and pressed the CUDA switch for good measure too and eventually I succeeded! :D

FW TDM is restored.

The boot menu is now available: with option held down, the eMac detected my Tiger USB installer. We can add this machine to the list of PPCs that are able to install OS X via USB directly from the boot menu. Open Firmware is also available again normally.

Thanks @eyoungren and @alex_free. Now I can use the computer without those hobbling restrictions. I'll look out for a cheap 512MB module to bring the RAM up to the maximum 1GB and my next question is this: have any of you ever replaced the eMac HDD with an SSD? From what I've read, accessing the HDD appears to be a nightmarish task and a last resort to only be embarked upon if the drive fails.

Are you sure? :D

Cool - I love going through someone else's audio library to potentially find new gems I wasn't previously aware of too. Same with software.

Not with a SSD but a 500GB 2,5" SATA HDD using a IDE > SATA adapter.
It's not as easy as working on a standard PM G4 but much easier than opening an iBook or 12" PB as all the party and screws are bigger and easier to remove.

Basically you have to remove the motherboard assembly from the CRT unit. There are a lot of connectors to carefully look out for, especially the power button cable as it is the easiest part to break in the process.

Follow exactly the steps in the iFixit guide https://de.ifixit.com/Anleitung/eMac+Hard+Drive+Replacement/104258?lang=en if you want to succeede!
Best to place the eMac front facing down on your bed or a towel on your work bench and take some photos in the process to remember where each connector has been sitting

😂 The seller also offered me first refusal on an iMac G3 DV SE 400Mhz - I had to find the self-control to decline. It was a struggle but I managed to do it.

Likewise! The iMac G5 that I found on my street had a Fleetwood Mac CD in the optical drive and a suite of software including Photoshop.

The eMac has great speakers so a nice machine to be listening to new music on!

Agreed. I'm eager to see how it fares with the audio from films too! :)

Anything that's easier than working on an iBook already sounds like an achievable task! :D

Thanks for this. If I decide to take the plunge, I'll follow that guide meticulously. :)

Glad that worked out!

I still have the original hard drives in my PPC Macs. "3" GBs in the iBook and 80GBs in the Mac mini. I use the mini as a server/media player as it's connected to my TV and it has an external hard drive connected with a SATA to USB adapter. Another Open Firmware tip if you don't already know, the command:

multi-boot

brings up the boot menu. I have my Mac mini set to always boot to Open firmware because I have a wireless keyboard that does not work until so late in the boot proccess that command key+Option or any other boot commands can't be accessed.

it is indeed :D
Be careful with the CRT though, there is no need to "unload" it properly for this task, but be careful to not harm yourself in the process ;) aside from the high voltage there are many sharp edges on the EMI shield and motherboard tray, watch out for them as well

If you do that, there is the chance that you lose access to the free music collection if it is DRMed to the previous owners iTunes account. I have an iMac G4 with about 30GB of the previous owner's music on it but it will only play via iTunes because: DRM.

Thanks for the warning but they don't appear to have been DRMed as they're playing without any complications on my MBP under El Capitan with QuickTime, iTunes and VLC. :)
