| Who has a iMac G3 with either a Sonnet Harmoni processor upgrade and or a item that uses the Mezzanine slot? | |
| Posted by: Angelgreat on 2021-09-26 18:37:04 I would want to know if someone has or had use them. Feel free to post your experiences. Please add a photo if possible. | |

| Posted by: jeremywork on 2021-09-30 02:43:59 I haven't grabbed a Rev A/B, but I have stored pictures away as the auctions have gone by. Here's what I've seen: --- First, there's the Griffin iPort, which uses the physical slot opening but not actually the mezzanine interface. The PCB runs cables to the standard 8-pin mini-din serial connector for the infrared port and the DB15 port for the internal CRT to provide both interfaces externally.    --- Then, there's the iPro RAID, which was delivered in two versions; one with an ultrawide SCSI controller and another which also bundled analogue video (/tuner?) input. (only one picture of this available) This card does use the mezzanine interface. I actually have one of the SCSI-only models in box, despite not yet finding an iMac to put it in...      --- And finally (that I know of) the 3dfx Game Wizard, which adds Voodoo II acceleration to the onboard display.    --- And also, the Sonnet Harmoni G3 500 or 600MHz, which occupies neither the Mezzanine interface nor the slot opening when installed.     | |
| Posted by: LaPorta on 2021-09-30 05:23:45 Thanks for the photo: my iMac is happily secured in its original box, it would have been an ordeal to take out and photograph. | |
| Posted by: CC_333 on 2021-10-01 23:05:25 I so want one of those Harmonis! Alas, all are too expensive for me (I thought $400 for one back in 2005 was expensive, but in retrospect, that price is actually quite affordable, because these often go for 2x more!). c | |
| Posted by: ArmorAlley on 2023-05-17 12:03:55 iProRAID There is an iProRAID on sale on eBay Germany with a BIN Price of €22. I've posted more about it in a Trading Post thread. | |
| Posted by: StevieC on 2023-05-25 19:37:15 I wonder whether there would be a way to adapt the brains of the DVD PCMCIA decoder card for the PowerBook G3 to the Bondi Blue iMac's mezzanine slot? | |
| Posted by: Forrest on 2023-05-25 20:01:45 Sean of Action Retro recently posted a video installing a Harmoni G3 into an original iMac | |
| Posted by: macintosh2002 on 2023-05-28 09:36:11 i also have an iMac G3 Rev. B with the Sonnet G3/600 Harmoni in it, got that Sonnet Card for 25 Euros, it was in a broken iMac (seller didn´t know what he had...) | |
| Posted by: maccitbike on 2023-12-19 21:50:34 I also have a - literally - fully loaded rev. B iMac with the following: Sonnet Harmoni G3 500 Mhz iPro Raid TV SCSI TV tuner card 512 MB of RAM Adapter to connect an external monitor (forgot the name of it). By now it is 24 years old and I am still using it to scan with an Epson scanner connected via SCSI. I once had to replace the flyback transformer of the CRT because it was arcing. Pictures will follow. Cheers | |
Posted by: Phipli on 2023-12-20 00:54:47I also have a - literally - fully loaded rev. B iMac with the following:That's quite a setup. We don't see a huge number of project G3 iMacs here. Good to hear about one. | |
| Posted by: 68kPlus on 2023-12-20 01:45:39 Woah that's awesome! Would love to find a Rev A/B/C/D iMac at some point, they seem like a cool machine to upgrade! | |
| Posted by: max1zzz on 2023-12-20 03:29:49 I have considered making clones of the SCSI only iProRaid but figured there wouldn't be enough people interested, it's a pretty simple card and would be easy to clone. Also did about making a iMac SATA card but also figured the market would be too small for it to be worth it (plus there are licensing issues around the firmware that would need to be used) | |

I hear the molex connector for the mezzanine slot is hard to come by. | |
Posted by: maccitbike on 2023-12-20 13:49:22I also have a - literally - fully loaded rev. B iMac with the following:Here are the pictures as proof that I wasn't kidding. The box in the back is called Power R video adapter. There are three operating systems on the iMac: 8.6, 9.1.2 (?) and 10.4. I bought the iMac brand new in 1999. Once lightning struck and the Ethernet port died as a consequence. I temporarily replaced it with a USB to Ethernet adapter (ran only under OS X10.4, not 8.6), later I replaced the motherboard. | |

Mezzanine in neueren iMacsBei neueren iMac-Modellen fehlt der Mezzanine-Slot, über den man frühere Modelle bis zur Revision B um so nützliche Erweiterungen wie etwa SCSI-Adapter oder TV-Tuner ergänzen konnte. Wer mag, kann aber den Slot eigenhändig auf sein Board löten - entsprechende Lötpads für den Stecker sind nämlich...
Here is an article about retrofitting the molex connector to later models that don't have it because Apple noticed what was going on and didn't like it 🙂 The article is from the best German Computer magazine, c't, Google translate should help to read it in English. | |
