You haven’t measured voltage across the legs of the smoking capacitor, but you should because it must be over voltage that is causing it to smoke. If it was a matter of polarity being reversed, I would expect it to pop rather than just smoke. Unfortunately, if the smoke is indeed coming from...

I came across this impressive 100% transparent Apple "Hello" model today: https://facfox.com/case/art-case/sla-3d-printed-apple-liquid-glass-hello-ornament/ Here's one of the images from that web page: It probably would look fantastic if printed in JLC 8001 Transparent Resin, but alas there...

Hi, Daryl. Thanks for posting the video. Smoke is evidence of a serious problem. You have a "dead set" which is mentioned on page 109 and later in Larry Pina's book here: https://archive.org/details/macintoshrepairu0000pina/page/108/mode/2up If you flip through the next few pages you will...

The Clear case came out first and I found the tabs to be weak, but MacEffects strengthened them in a subsequent production run, and I confirmed that. The Black case was released after the Clear case and has the same thickened tab revision. So in the end, I can say I am pleased with both cases...

I like your idea better than my "as is" EYOYO because yours can be tilted more nicely, is collapsible, and won't slide off the top of the IIc. Here's my setup ( @MacEffects black case)... Your 8" EYOYO seems to be a genuine product, as shown here...

I had never heard of those before. But I see they are pricey and SOLD OUT too... https://shop.pocketchip.co/collections/frontpage/products/pocket-c-h-i-p-new

@RolandJuno Thanks for participating in the forum. As a 5126 owner, I loved reading your detailed writeup! And I think your avatar is pretty great too.

I just released the full LC520 recap and overclock walkthrough video...

I put a comment on the developer's YouTube channel asking about a 2X upscale (nearest neighbor) and the lack of sound. He said the 2x upscale is doable, but he avoided the sound effects, thinking most people would turn them off anyway.

But is that worth $170? Especially when I don't have noise issues with my stock SONY PSUs or my SEASONIC? In my opinion, it is not worth $170. Sure, it's nice to have a modern, well made power supply. But if you watch my SEASONIC video from 2018, I was able to get such a PSU and...

Even the lower cost PSU from TT shows the same 5V rail voltages, which is what I would expect... https://github.com/tt-design-studio/psu-mac-se I'm therefore not seeing the practical benefit of the $170 version over the $129 one.

Thank you for the detailed info! I assume you don't have any of those PSUs yet and are merely mulling which one to buy? As I thought, even the top end PSU costing $170 cannot get around resistivity losses due to it outputting close to 5V. That is shown by the voltage measurements presented in...

Thank you for your kindness, but you may not need to re-run it in v3.06. I just downloaded v3.23 and checked its version history, which indicates the only change impacting 040 processors (not the 030 like you and I are testing)... This also means none of us should use Speedometer versions...

I did not use Speedometer 3.23, unfortunately. When checking the Speedometer 3 page on Macintosh Garden, it says this: Note: Algorithm changes occurred at v3.01 and v3.1; so absolute benchmark results across those version boundaries are not strictly comparable. That implies that the 3.06...

@fehervaria Very odd I missed seeing your thread (started back in 2021) until today! Wow! So the interface shown in your opening post allows you to use ADC displays on modern computers via HDMI? Or does your adapter allow the vintage computer (like a G4 Cube) to connect to modern HDMI...

I have not. I have only reviewed the BabyFace PSU. I believe that TT Design version came out AFTER the BabyFace was released. Not sure who "borrowed" whose idea, but they both use the same "modular" voltage conversion units. And in my testing, I can tell you that you will get loss through...

So... We should the following? 1. Connect one end of a normal Mac serial cable to the vintage Mac. 2. Connect the other end to a serial-to-USB adapter, then connect the USB plug into the modern Mac. 3. Launch Basilisk II (System 7.1? 7.5.5?), then launch TinyTransfer from within Basilisk II...

And here are the MacBench 3.0 results, showing that CPU/FPU are essentially the same for your board and mine, but your board still shows a bit higher on the Graphics... Even so, if you consider how much lower the Graphics scores are with the 25MHz LC520 board, I don't think it can be said...

Hmmm... I just did the side-by-side with your Speedometer 4 benchmark results (shown at right below — I renamed your record), and my overclocked LC520 board at left. All numbers (except Disk) are clearly within "testing error" difference. So I guess this gives strong evidence that the BUS...

@kefkafloyd Thank you. I downloaded your file and opened the Speedometer folder and I see Records "3 & 4" but do you which specific version of each? As you can see below, I have my own 3.06 and 4.01 folders (top left). I believe the creator of Speedometer changed this testing methodology...
