    Apple Studio Display M7649 CCFL to LED conversion

    @JDW oh, I have no idea. I hadn't even heard of the effect until you mentioned it. I saw that 20" iMac a while ago on yahoo auction and was really wondering what could cause that. I thought it was just liquid damage. But yeah, I guess it was stored in an extremely hot place for too long? But...

    Apple Studio Display M7649 CCFL to LED conversion

    Oh no, that’s terrible. Yeah I remember that 23”, it seemed impossibly big when I gawked at it in the Apple Store. Is the vinegar syndrome this effect?

    Apple Studio Display M7649 CCFL to LED conversion

    this is so cool. I have an iMac G4 17" and I have an extra display. I would love to try and do this to the iMac display.

    G4 Quicksilver successful rescue

    My very first Mac was that exact same model (without the Zip drive). If I remember correctly the 733MHz model of quicksilver was an education only model. Because I was in high school at the time, I was able to buy it. It was bare bones but it was a Mac and it was beautiful. It came with Mac OS 9...

    iMac G4 constantly crashing/kernel panics

    Oh yeah, and the other thing I forgot about is that if you did open the machine, did you reapply thermal paste to where the heat sink connect to the upper shell of the case? Or I guess, can you relate the timing to when the crashes started to right after you worked on it? Or was it months later?

    iMac G4 constantly crashing/kernel panics

    its hard to say. Usually freezing like that sounds like a RAM issue. Especially if it's so consistent. When you said you maxed out the ram, did you max it to the unofficial max or the official max? But that would be the first thing I would go for is to remove half of the ram (like the user...

    Guide at Attempting First Recap

    @Garrett thanks for the reply. Here are some photos of 1 of the boards. I am kind of wondering how to find the correct capacitors to order. And yeah, since these boards don't work, I don't mind if they continue to be broken.

    My very first NeXTStation

    I googled it and that looks like a pretty sick retro laptop. That said, I think it's hard to beat the original Black hardware.... it beautiful inside and out... I wish I still had mine. And I never said a big congrats to @eric on getting his first black hardware set up and working! Big...

    Guide at Attempting First Recap

    Hey folks. I am in no rush, but I have 2 iMac G4 logic boards that won't boot. I won't go into the details, but I can't see anything wrong with them physically. However, on one of them one of the capacitors just fell off and I noticed the telltale signs of some capacitor residue on the board at...

    My very first NeXTStation

    NeXTSTEP has a lot of great commercial software including Word Perfect and Adobe Illustrator for example. It also has OmniWeb which is a fantastic web browser, that was later used on Mac OS X until it was crushed when Apple introduced Safari. And as I said with the software development, the...

    My very first NeXTStation

    I agree with this sentiment, but NeXT machines are far more powerful than the Lisa and non-powerpc Macs and have all modern-ish connectivity. Meaning they are a far more useful machine. And because NeXTSTEP is the basis for modern OS X, it works in a way we expect with the same application and...

    iMac G4 Logic Board Diagnosis and Repair: Is it possible?

    Thanks for hanging in there with me. I didn't remove the logic board from the bottom plate. I did when I first got the Mac for cleaning but haven't done it again since the problem started. I will try this weekend and see if there is anything noticeably wrong.

    iMac G4 Logic Board Diagnosis and Repair: Is it possible?

    The only thing I can think of is it doesn't like the ram because it's DDR333 PC2700. It's what Other World Computing sent me when I ordered RAM for the machine. But technically the RAM it uses (according to the service manual) is PC2100 SDRAM DDR266. Not sure if that matters. That said, it...

    iMac G4 Logic Board Diagnosis and Repair: Is it possible?

    Yeah, I tried both slots where the other slot was left empty. I have multiple ram sticks for each slot.

    iMac G4 Logic Board Diagnosis and Repair: Is it possible?

    I have a 1GHz iMac G4 17" and I have been using it almost daily for the last 3 months or so. I mostly use it as a secondary video player while I use my main computer. However, recently it started booting up to 3 beeps. Normally this would mean its bad ram, but I tested 5 or 6 different ram...

    Tutorial: Streaming Youtube (or any video content) to PowerPC Macs

    I updated the tutorial to fix the main shortcoming before, which was a bug in FFMPEG when capturing from AVFoundation. Now I use a Linux VM to do the FFMPEG streaming. It is much better now because the Audio is full quality 192K AAC 44,100Hz. https://github.com/jeffreybergier/Retro-Stream-Tutorial

    @joevt thanks for the pointers! As I said I have never done this. Good to know Hopper will not help me :)

    Keychain and OS 9.1

    Sorry, I don't have much experience with OS9. But in OS X, the keychain automatically unlocks when you log in IF the login keychain has the same password as your user account. To me it sounds like the password you think your keychain has is wrong, but it perhaps matches your login password. You...

    Software Update Server Mirrors

    That client and server works differently, so no. However if I get time, I want to try to reverse engineer the payloads that go back and forth so I can try to rebuild them. But as there are no copies of the server responses online (that I can find), it will be hard. I think I will need to...

    Software Update Server Mirrors

    An update here! It works!!! If you didn't know, Apple shut off the Software Update Servers for Mac OS X 10.0 through 10.3. Luckily the servers for 10.4 and above still work. But I am worried those may be shut off as part of the TLS Apocalypse. For that reason, this week I went through the...
