@retr01 The metal chassis of the compact Macs, and the metal bar on the motherboards, provides both mounting stability and ground. Your hands will come in contact with the metal chassis, so ensuring all those metal parts are grounded is needed for safety. It's no different on your car, where...

@Kay K.M.Mods knows more about that. As I am sure you saw recently in his post here, he has experience in both plating and painting. (Earlier in that thread he shows photos of how neat a black chassis looks too.)

Holy cow! That's a seriously battery-bombed board. Well, I must say that even though mine wasn't that far gone, such that I was able to remove the rust and continue using it, having a brand new replacement would have saved me hours of time. And for people in your shoes (which no doubt are...

It comes in contact with the metal chassis and provides a solid chassis ground. It also adds mounting stability to the motherboard, although with the back case on that may not be a major issue. BTW, if you have a photo of your rust-eaten metal bracket, I'd love to see it.

Folks, there's a discussion here about Bourns filter replacements, which has expanded to replacements for the metal bracket and for the plastic mounts for the Reset & Programmer's switches here. Please check it.

Holy cow! That's incredibly useful info! Thank you for posting that! I covered the 2032 battery in my video series, explaining it would get less battery life than the original, which is partly why I deliberately installed the stock holder instead of a CR2032 holder. So long as one could get...

Thank you for sharing those detailed thoughts, gentlemen. Because the Reloaded build costs more in time and money than a $140 SE board sold on EBAY, I mention that fact in my videos, suggesting people think of it instead as a thrilling project whereby they are building the heart and soul of a...

The reason I asked about your excess PCBs is twofold. First, my video series on the SE Reloaded project has given me knowledge about replacement chips. For example, @max1zzz created a replacement for the ROM chips. Kai created replacements for the ADB and SWIM. And of course you created...

Still pondering this. One obstacle is cost and waste. You see, all the major PCB makers require no less than a 5pc order, which means 5pcs of the panel, which yields a whopping 120 Bourns Filters! I realized that one SE motherboard takes 4pcs, but 120pcs/4 = 30 motherboard's worth! I...

Oh drat! Now you've got me hungry for popcorn! 🤤

SE Reloaded Part 3 is now Public for your viewing pleasure: That completes the build. Please read the text description that I lovingly crafted for you under the video, as it contains a wealth of information. Mouser Cart is in my Parts List. I wish to humbly thank @Kai Robinson for his...

@retr01 But if one argues that it is the Jumpers, it then becomes a matter of "why did a second error appear after cleaning with IPA?" If that board had been tested prior to the recap, it would have been informative insofar as we could rule out the new caps and related soldering as having been...

Well, it seems like you got this error even before recapping... That indicates your recapping has nothing to do with the problem. I was merely curious if there was a dry contact. But if you've reflowed the caps, then they are probably ok. It's a curious thing that you say you cleaned the...

Sorry, I didn't reply until now. I'm still quite busy finishing off SE Reloaded Part III, but I want you to know that I did spot your email to my Protonmail account a few moments ago. I just want to quickly ask if you really put enough solder on your replacement caps? The photo below looks...

Kay said it is from an "iMac Rev. B" which he used in 2005. But it also seems he uses a Sonnet HARMONi G3 600MHz, which he overclocked to 666MHz.

That compatible B&W CRT is incredible! And the fact you put the CD access at the back instead of the front is a very nice touch! That machine was lovingly crafted in every way imaginable. And incredible amount of work, but with a very stunning result!

What? You mean it doesn't stand for Pretty Little Cute Chick? ;-) Seriously, except for FBI, CIA, IBM and a few other very common ones, I'm usually one to get lost when many acronyms are used. Same in Japanese, although I've learned the most common ones. They don't use English letters, so...

Here...

I finally got the rusted metal bar desoldered. Here's the BEFORE photo... After about 2 hours immersed in CRC Rust Remover (phosphoric acid) -- having removed it a couple times to rub it with steel wool -- I washed it off with water and baking powder (to ensure the acid was neutralized), and...

@Kai Robinson is on the TD board, and we know he has Polo Shirt design skills. Not sure if he has the time or the desire, but if he does, that would be yet another cool feather in his cap! Hint, Hint, Kai! 😇
