77 DPI for the Mac Portable is expected and matches my Spreadsheet value. But the 84.8 DPI for the PB100 is at odds with the 81 DPI calculated from the measurements of @T-Man . I personally prefer metric measuring devices, unless the ruler or measuring tape in inches has super fine divisions...

DCM solvent welded Polycarbonate Rib Reinforcement for Mac Portable

Well, I'm actually glad to hear you feel "it's a toss-up" because I already DCM solvent-welded the transparent piece to the back of the ribs today on my lunch break. :) I will shoot some photos for you this evening after work. The only thing I've not yet decided is if I want to drill in order...

I cannot speak as broadly as "all 68K Portables," but the first trio of MONOCHROME PowerBooks were square corners.

@joevt Thank you for your advice! It seems you are suggesting that I do NOT DCM-weld the transparent plastic piece over the backs of the ribs and instead use only JB Weld Original all across the back. Correct? After many hours of research with ChatGPT, it seems the better JB Bumper Weld...

@T-Man & @joevt ChatGPT is faster than using a calculator when you already have the basic template, which I filled out using the measured data of the previous post as follows: Monochrome LCD screen with square pixels. Resolution: 640x480 pixels Height: 5 2/8" Width: 8 4/8" Diagonal: 9 7/8"...

Steps to Success with Photoshop 1.x 1. Launch the app. 2. CMD-N 3. Set your screen's native resolution (640x400) and click Gray Scale and then OK 4. Choose the Paint Bucket Tool and fill the window with Black. 5. Look at the very bottom of the toolbar at left, and click the rightmost icon of...

Thank you for replying, but I need to clarify when you mean in your second post. What is "575"? You measured 19.5cm diagonally with a ruler or measuring tape, using an all-black screen, from the very bottom left corner to the top right corner? I'm rather confused by what 24.4cm means because...

I finished stripping off the chrome paint by hand using mostly a box cutter. I did the sides of the ribs too. My plan was to use DCM to solvent-weld the transparent polycarbonate piece to the back of the ribs and then after that stuff JB weld (original 24-hour cure) down in between the...

Well, folks. I decided to do the DCM weld this afternoon, and here's how it turned out...

I wasn’t aware of any cloned messages at all. Interesting. What I can say is that whenever I use my iPhone to write a reply here on TinkerDifferent (within mobile Safari), when I click the “Post reply“ button, sometimes nothing happens. I don’t see my reply posted. So I reload the page and then...

@Kai Robinson Thank you so much for your reply! In answer to your question, I’ve been desperate over the past month to get in touch with @techknight because he has the most experience repairing these machines and he also decided NOT to use a replacement CCFL tube or even LEDs, and he instead...

If you are talking about why I linked to that discussion in the other forum, the answer is because if we don’t say anything here, I think some people might Google that other forum, and be a bit confused about whether they need to encode or not. But as we discussed here, it seems to be pretty...

It took two hours, but I was finally able to open the plastic LCD housing, and in this video I show the CFL tube. EDIT: I later found that the piece of tape does not secure the paper wrapped around the tube. The tape seems to be there to better ensure the paper rolled around the tube won't...

How to open Mac Portable’s LCD Housing?

Problem now is that I cannot for the life of me get the LCD housing open. SOMEHOW I was able to do it in the past because I recapped the INVERTER board. But no matter what I try now, it simply will not come open. WHAT I'VE TRIED (AFTER REMOVING THE 2 SCREWS): 1. SERVICE SOURCE says to insert...

@Mk.558 It isn't clear from your post if your photo is the 5120 or 5126. It seems like it might be the 5120?

I found a YouTube video from a fellow opening his 5126 LCD housing, and took the following still images from it... As you can see from the above, two wires lead from the INVERTER UNIT to each end of what should be a single CCFL tube inside that metal shield. The metal shield appears to be...

Very sorry to hear that. I do hope your RAM card is OK. I've heard that CCFL backlight tubes can flicker when dying, so hopefully it's nothing more than that. But as to why your RAM card doesn't work, well, can you run the Portable without the card installed at all, just using the onboard...
