@RolandJuno Thank you so much for answering my Question #1 !!! That's the GOLD MEDAL ANSWER! 🏅 More specifically, from the part of the video you kindly linked for us, large pliers are required to squeeze that protruding piece (see below), then push inward to pop that piece out the other side...

Well, “removing” the cylindrical hinges from the left and right sides is truly easy, just as you kindly showed us. But how to OPEN/DISASSEMBLE each of those two hinges after they are removed, in order to lubricate or check lubrication, is still the mystery. (Question #1 in my opening post.) No...

You mean recreate the entire main structural piece? It's a pretty complex frame, as you can see at right in tech knight's video at 11:34. Bruce Rayne shows it even more clearly in his video here. That main plastic structural piece is basically holding nearly everything except the keyboard and...

In my review of the BABY FACE, oh yes. I had a lot of noise on the 12V rail shortly after power on, such that it even appeared on the CRT. I show that in my video with scope measurements following, starting at 23:29 below...

My experience with sub 1.0mm drill bits isn't good. They almost break when I look at them! :) Seriously, they aren't strong, and that's why I earlier said that even "titanium" at those diameters might not even be adequate. (Mitutoyo calipers used for all measurements.) Underneath the 5...

OK, well... While I ponder the toxic and cancer-causing risks of Weld-On 16, I'd like to go back to my Question #1 of my opening post, which no one has touched on yet. And maybe nobody replied to Q1 because no Portable owner has ever considered lubing the two removable hinge parts? @techknight...

@phunguss I greatly appreciate your input! Luckily, both 4 & 16 are sold on Amazon Japan, although 4 is more expensive than 16 because it comes in a larger quantity can. I asked ChatGPT to compare ingredients and tell me which provides the best weld for Polycarbonate — an important...

@Paolo B I greatly appreciate your time to offer some thoughts. Those ribs are tiny. Drilling top-down into them for the sake of inserting a metal rib (the source of which is currently unknown) is scary to me, personally because the size of the drill but would need to be super tiny. The...

Help, “Pretty please”? 😢

Voltages are lower with the Meanwell module type replacement PSUs. When I reviewed the Baby Face PSU, I compared it to the Stock SONY and to the SEASONIC modern replacement PSU, putting voltage measurements in my spreadsheet below...

Two questions for my fellow Portable owners, including @techknight … Question 1: What is the step-by-step procedure to clean and lube stiff hinges? Question 2: My Portable’s screen was always hard to open, requiring me to press very hard on the right side of the handle to open it. Tonight I...

Correct in that my joystick kit does NOT include the "rubber sleeve" that slides onto the shaft. I found a YouTube video with a greed colored rubber sleeve on the shaft as shown below... Again, mine didn't include that at all. Not sure if that's good or bad, but the product page shown below...

Welcome to TinkerDifferent! With the exception of the floppy drive (which doesn't matter in this case), you clearly have a fully recapped machine. Not only that, but you also did this... By HOT you mean the BU406, correct? If so, great call. Reflowing all the connector joints was also a...

"Rubber"?

@muse I was guessing that was the case, but if the use of the FLAT round plastic piece is going to make it better for big, fat-fingered hands, why don't they all ship that way? Is the DOME shaped plastic that's installed by default on there purely for aesthetics? Or does it enhance the...

Do you have the same joystick shown in my photos? I've read THE MANUAL for the ArcardR joystick I received, but I am not seeing any mention about what in the world this round piece of plastic is for, although the hole suggests it goes on the stick itself? I'm also curious as to why a...

No tariffs or tax on that joystick box, although Japan Customs will probably tax me the standard 10% sales tax on the C64 Ultimate because the declared value will likely be more than ¥10,000. I say “likely” because it’s coming from the Netherlands and not straight out of China. Chinese companies...

And so it begins! No C64 Ultimate yet, but my joystick order arrived today from the Netherlands. Amusingly, there was only a single piece of cellophane tape holding the lid down! Not sure what to do with all these spare parts! Guess I need to use the QR code and read the manual

@Mac84 Toward the end of your video, you said some friends failed to get the CDs to work in IBM RS/6000 machines, but were they PCI based? ChatGPT tells me this: CHRP’s platform topology calls for a PCI host bridge. IBM’s CHRP machines were designed around PCI I/O rather than older proprietary...
