@@a531016 I'm not sure for that particular iMac but my Bondi Blue one used a slim laptop style cdrom that connected with a single ribbon cable like what you would find in a laptop and it supplied power to the CD drive and allowed for the bus as standard.

I believe the bigger ribbon connecter is for power to the cd drive but could be wrong I know the hard drive has the 4 pin molex. I also believe this was done because apples disk drive back then was only compatible with macs and also so they could make the iMac compact assuming having 2 sets of molex could have got in the way of something
I really appreciate this breakdown tutorial. With my limited knowledge I've resurrected over a dozen iMac G3's left out in the cold by frustrated owners.

I worked at Apple from 2000-2010. When I started we had to learn how to tear down and rebuild these. The Faraday cage would bend and break after 1 or 2 reassembles. It was such a bitch to work on if it had already been previously serviced.
Awesome, will you be trying to use the original CRT, a replacement CRT or a different screen all together? Let us know how it goes, we'd love to see the results if you wanted to share on element14.com?

I understood that the G3 went through a number of revisions, including an x86 version? I could well be wrong though, or equally have been looking at an incorrect source?
@@a531016 The PowerPC processors I remember were the 601, 603, 604, G3, G4 and G5. Macs started using Intel processors in 2006. There have been Mac models that had an Intel processor on a card to allow them to run Windows software. I don't think they were very popular. The G3 was pretty amazing when it came out. I had a 603 system that I upgraded to a G3 via the processor cache slot. It think it made the system something like 3.5 times faster.
@@a531016 I doubt they would be able to make an x86 compatible PowerPC or even wanted to try. Also, the G3 iMac would've competed with Pentium III PCs, which were typically fanless, the quintessential version being Slot 1 cartridges (though there were also socketed and BGA versions).
Thank you for including the boot up sounds! So much nostalgia 🤘 a very interesting tear down! I’ve never thought about that there are people out there that have never used dial up... I honestly didn’t hate it, the internet felt allot more precious and less disposable a pass time
I didn't even own a Mac, and it took me back too. Even the sound of an older mechanical drive spinning up and the loud clicking took me back to 10 years of again! Remeber before there were "all you can eat" internet plans, and you were charged per website?
Most likely the power regulation board is taking in low-voltage AC (20V?), and switching / smoothing it down to the levels needed by the logic board. If you look at the connector, it marks two of the pins as AC+ and AC-. That's how they would be able to get away with powering it via those long traces, where voltage drops from trace resistance is not as much of an issue. Why does the Apple Chime sound have to come from the HV board? The CPU could produce the sound shortly after boot, and you wouldn't be able to notice a difference from the time you pressed the button to when the sound played. Having the HV board produce the sound would prevent it from being used as a diagnostic, since it wouldn't involve the CPU and would instead function as an auditory power light. Having the CPU produce the sound could at least represent that the CPU is able to begin executing the boot code. (i.e. the RAM works, the CPU works, the sound chip works, and the BIOS was read and not corrupted). That could be done before the POST is completed, since the POST can then be done while the CRT is warming up.
That's a good point. I guess being a PC user I am used to (certainly at the time) discreet sound cards that need the the OS and drivers to work. As the sound processing and bios are in a bespoke package it would have been possible?
@@a531016 I don't know for certain, but I think the fact that it was a custom VLSI package helps. Most likely, one of a few things were implemented: 1) the sound chip is really simple, so it doesn't need much of a driver (so the BIOS loader can load it), 2) the BIOS used a stripped down version of the driver just to play the startup sound, 3) the BIOS had a hardcoded routine to play the sound file (think of it as optimizing the driver to only do that one task). Given that the sound chip was set and could not be upgraded, any number of those guesses could be true. Though, my bet would be a combination of option 1 and 2, where the sound chip was easy to control, and the first thing the bootloader does (besides set CPU registers), is to send the startup sound to the sound chip. Anyway, others have verified that the startup sound is in the BIOS ROM, so it's clearly coming from the CPU. I would suggest probing it to find out how much work the CPU is doing beforehand, but since everything is BGA, it probably won't be feasible. You could probably snoop the BIOS (most likely it's SPI), and decode the contents in the order that they are being read if you are that interested. Since PPC is a RISC architecture, all of the instructions are 32-bit, and are well documented (it should be obvious when the sound data is loaded, since it will most likely be blocks of nonsensical instructions). That would be a lot of work to answer the question of how the CPU is playing the sound though. P.S. I am also a PC user, but I think this mac is closer to an embedded system since it pretty much comes in only one configuration. So in a sense, it probably has more in common with a system like the Nintendo GameCube than it does a PC of the era. Also, I am pretty sure that the GameCube played its startup sound from the BIOS as well (probably after the POST though).
The electron beam is not what charges the CRT up. The Capacitor on the board is just fine. If you remove the bulged plastic cover, the can inside will be just fine and flat.
On the observations about its power use and need for cooling, or lack thereof, compared to contemporary Pentiums...I hope that's what we can get back to with an in-house Apple designed ARM processor switch, just massively better perf/watt than the rest of PCs on x86. Ironic though, as the late PowerPC G5s were too poor in performance per watt - the whole reason they switched to x86 in the first place!
And ironic: as of late the intel x86 CPUs are now getting hardware security flaws, some going back like 20 or more years!! Which means software patches to stop the flaws, thus sucking down the performance
Wow. That thing is surprisingly dangerous, between the CRT, all those giant capacitors and the unshrouded power supply. I am very glad teenage me never followed through on disassembling mine. My untrained poking probably would have ended with a loud pop, a cloud of smoke and the smell of barbecue.
Damn what a coincidence just bought a Indigo 400Mhz one with the mouse and keyboard for 15€ last week. Fun nostalgia trip but the 120GB HDD cap really sucks in modern times because it makes finding a new drive for it so much harder.
5 Minutes into the video you already told that the GPU was the CPU and that the IDE interface with additional power lines was a SCSI interface. Sure, a 50 pin cable could be SCSI, but where would the optical drive get it's power from then? ;-)
I know this was more about the electronics, but just wondering if you remember if there was any space between the front bevel and the monitor? Was thinking of lighting it up with LED's but don't want to risk breaking it if I can't get them in anyway.

Why would you say that? It not a Windows clone. The iMac is part of our history just like a IBM PC. If you have the room a display of older computer equipment is a great conversation starter for any family gathering. But as dumpster food not so great. ✌️
