    Flippy-Floppy Video REVIEW

    That is a good question for @Kay K.M.Mods I don’t have an Apple III myself.

    A Terrifying Phenomenon I Discovered While Repairing an Analog Board

    Wow. This is the first I've heard of that problem. The 128K through the Plus use essentially the same Analog Board, so it would potentially have implications for all of those machines. Even so, your report is the first I've heard of such a problem. And I've been in this hobby since about...

    Custom USB-C powered 8"display for the Apple IIc with STL files and build plan

    I also have Plamen's IIc to VGA adapter, and since my Eyoyo has VGA as well as HDMI, I could compare it with the A2DVI interface. The main issue I had with Plamen's adapter on the Eyoyo is that it wouldn't vertically center, and the displayed image was slightly smaller, versus the A2DVI...

    Custom USB-C powered 8"display for the Apple IIc with STL files and build plan

    There’s an even smaller version of the same exact thing made for the IIc that came out AFTER I acquired my setup: https://tinkerdifferent.com/threads/announcing-the-a2cdvi-v2-5.4582/ That new compact version won't as a card inside a IIe (which is really what the card I have was made for), but...

    Custom USB-C powered 8"display for the Apple IIc with STL files and build plan

    @ArjenCNX All excellent info, especially the EBAY link. Thank you! One question... Would it be possible to shrink your bezel to fit the 10" LCD inside? I've not opened mine to know how much extends beyond the LCD itself. True, I am partly asking because I already have the 10" display...

    Custom USB-C powered 8"display for the Apple IIc with STL files and build plan

    Gentlemen, There are three points of concern: 1. The LCD used by @ArjenCNX measures 8 inches diagonal. The (fake?) Eyoyo I bought from AliExpress is 10 inches diagonal and therefore cannot fit inside his existing plastic case design. I just checked Amazon Japan for his 8" Eyoyo model S801H...

    C2 Capacitor Replacement on Mac 512k Analog Board Smoking

    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...

    3D Printing & MacEffects Appreciation

    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...

    C2 Capacitor Replacement on Mac 512k Analog Board Smoking

    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...

    Custom USB-C powered 8"display for the Apple IIc with STL files and build plan

    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...

    Custom USB-C powered 8"display for the Apple IIc with STL files and build plan

    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...

    After Dark Flying Toasters ported to OS X PPC Macs!

    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.

    Comparison between Babyface and TT Design PSUs for SE/30?

    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...

    Comparison between Babyface and TT Design PSUs for SE/30?

    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.

    Comparison between Babyface and TT Design PSUs for SE/30?

    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...

    LC520 Overclock

    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...

    LC520 Overclock

    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...
