If indeed @Branchus is correct about RF11 being 390Ω (which means the stripe which looks Yellow in his video is in fact White), then with a Gold 5% tolerance, your measured resistance should lie between 370.5Ω & 409.5Ω. But you measured 363Ω, which perhaps indicates that burned resistor is...

A type-K temperature sensor attached to a multi meter would be able to verify the temperature measurements made by the Flir. The metal tip on the wire of the temperature sensor with need to be strapped onto the resistor using a wire tie. Although circuit boards are used as heatsinks all the...

Thanks for the extensive testing and photos. The 1N5237B (DF2) seems to be a 1/2W 8.2V Zener. And from your Flir hot-spot test, I see that DF2 is getting quite hot, along with RF11. Also is interesting to see that your massive 5W RL62 replacement still rises to 90.6°C. I agree that RL22...

Another thing that has me baffled is why there is hot-glue only on that RF11 resistor. There are a number of raised resistors on the board, but they don't have hot glue on them. What is so special about RF11 that necessitated hot glue? Hmmm...

DRIVE Right now, I am seriously thinking about buying that $10 mSATA 128GB drive from NewEgg and getting it shipped to my daughter since she will fly back to Japan at the end of April when her semester concludes. ADAPTER I found what appears to be the same mSATA to IDE adapter that @trag kindly...

I assume you swapped out your burned RF11 as well, because it looks quite burned indeed... On my board it looks like this... Looks like RED, YEL, BLK, BRN, but BRN must be GOLD. But RED, YEL, BLK, GLD = 24Ω, which can't be right. If we say it is ORG, YEL, BLK, GLD, that is only 34Ω...

I am not an expert on those cables, so I cannot say exactly what the thinking is. But there is a tiny amount of resistance in any set of wires, and that always means a tiny voltage drop. I doubt there's enough resistance in your typical flat SD card extender to necessitate any special...

Oh. So it seems the "cable" being discussed is the ultra thin ribbon cable of SD card extenders, not a SCSI cable that I had been thinking until now. I have two SD card extenders and didn't have issues with either in my testing of BlueSCSI v1, although I've not tested them yet with v2 because...

Thank you for that clarification! When I made my VGA mod video, I spent a lot of time researching the matter because there was a fair amount of incorrect or misleading info out there on the web. Even in the Doping Mac book mentioned in my video, I found a small error. And while the info about...

I personally think most CC owners should swap out those two Zeners because every single Analog Board I've see has scorch marks on the PCB underneath them. And even if the stock Zeners are still working, I'd feel better to raise them up on their legs at least 1cm off the PCB for better airflow...

Just wanted to add further clarification to this thread, since some questions in the opening post were never answered, and people finding this thread over time may have the same questions. Yes, RL62 is 47Ω. But tolerance seems to vary. In your photo, the stripes, from right to left, look...

I am not aware of anything "preventing the use of a cable" insofar as I successfully use the OverEasy II "cable" adapter by @Stephen to fit between the external SCSI connector of my vintage Macs and BlueSCSI v1 and v2. I specifically use "Revision B" that is sold by @Kay K.M.Mods but sadly it...

Your having asked that question makes me assume you've never used a BlueSCSI v1 DB25 and loved how tiny and compact it is. I also have Stephen A.'s "OverEasy II" external SCSI solution which uses a long ribbon cable, but I've never found that to be a perfect substitute for having a tiny...

Thanks for the details. As you can tell from my Avatar, I tend to like my G4 Cubes. :-) Currently, all have spinner drives in them. So basically, if someone wants to follow in your footsteps with a G4 Cube that already has a hard drive and the side rails, all they would need to do is just buy...

Okay, so basically you did this... 1. Your earlier post shows the standard G4 Cube plastic mounting side rails, but you had to 3D print one because you seem to have lost one of the originals. 2. You purchased the Mounting Bracket only for the purpose of better cooling the SSD, even though the...

I clicked the "Adapter" link you provided, but I am not seeing that in your photo. Your photo shows the bare SSD in the bracket. Do you have a photo of how the adapter looks? It seems the SSD is supposed to mount inside that Adapter, or am I just totally misreading what you've done?

The only other thing I noticed about the PLA-printed sample I received (again, see my earlier post for photos), was that the little "lip" that I believe is supposed to go below the edges of the 040 CPU is very small. I've colored that in red below... I've not tested anything yet, but I must...

For an overclocked LC575 motherboard application, even when used within the smaller case confines of a Color Classic, I have not measured heat much beyond 60°C. Of course, I do have a fan added, and that tends to keep temperatures in the 50's or lower. Based on that, I would see PLA is...

@alxlab A fellow member of one of the vintage Mac FaceBook groups I participate in very graciously donated to me one of his heatsink clips that was printed by an associate of his, based on your design. It arrived today and I shot some photos... He said he used PRUSA PLA filament and...
