    Quadra 650 drive chassis

    Some views from most angles. My caliper is only Standard Units (USA), so you will have to convert to Metric.

    Quadra 650 drive chassis

    I have a Centris 650. Are you looking for the whole top shelf that holds the power supply and the 3 drives (floppy, hard, cd)? you will need a really large 3D printer for that project. It may be better to try to bend your own from Aluminum instead of steel. I should be able to measure it...

    Tecmar Mac Drive (10 MB) A serial hard drive?! (The first Macintosh external hard drive)

    Well that was only my 4 foot dish. I have an incomplete 8 foot dish here with a George Foreman grill attached at the focal point. My 12 foot dish was dismantled and gone (1100 3.5" hard drive platters).

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

    The DDR333 PC2700 will down clock itself and is backward compatible to PC2100. That should not be an issue. Anything loose? Can you see the bottom side of the complete board for any burns or scorch marks? Check wiring for possible break in insulation?

    Tecmar Mac Drive (10 MB) A serial hard drive?! (The first Macintosh external hard drive)

    I wonder if the platters are the rusty color or the shiny type (don't open it to find out)? When I built my first satellite solar cooker, I only had 3 5.25" platters that were shiny (near the center of the dish). The rest were all 3.5" and 2.5" platters. But it cooked hotdogs in the winter.

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

    There are two ram slots, an internal DIMM and an externally accessible SODIMM. You have swapped both?

    Can anyone help with installing open core to install macOS 15 sequoia

    You should NOT have to if your card was bios modified to work on mac.

    Can anyone help with installing open core to install macOS 15 sequoia

    Let's back up a step. You have Mojave installed. You can boot the computer with black screen and log in, then you get the desktop. The first step would be to install OCLP 2.4.1 onto the existing hard drive (don't even connect your USB Sequoia installer yet). OCLP should identify your...

    Can anyone help with installing open core to install macOS 15 sequoia

    There is a lot going on in that paragraph. Let's dissect it piece by piece. "I have enable_gop installed on the mother/logic board firmware/bios". There is no bios on a real mac. Enable_GOP is a setting inside OCLP to enable non-Mac cards. "I press option when booting" This is for a real...

    Can anyone help with installing open core to install macOS 15 sequoia

    Mojave does not require root patches, but Sequoia does. You should be using OCLP 2.4.0 or 2.4.1, either should be fine. There is one gotcha, and that is the USB 1.1 dropped support. To get around that, make sure your installation USB is 2.0 or 3.0 and plug in a USB hub. Main screen you should...

    Can anyone help with installing open core to install macOS 15 sequoia

    Did you install root patches ? What is Boot Picker Timeout set to? Have you tried it with the GOP option off? Do you have full acceleration (tansparent dock)?

    Can anyone help with installing open core to install macOS 15 sequoia

    If you are using a real Mac, then you should be using OCLP (Open Core Legacy Patcher), not Open Core. OCLP 2.4 works great on real macs.

    New platinum filament...

    What printer, firmware, and slicer are you using? I am using an Ender 3 Pro (with silent board), with similar settings to all other filaments. Using older Cura 4.1 on High Sierra.

    Apple Studio Display M7649 CCFL to LED conversion

    Based on the long length of the originals (listed as 15-23"), they will fit any size of these displays. A set of five delivered is US$37 from eBay, you could probably find similar items on Amazon or AliExpress, depending on your global location. So US$7 for a set of LEDs and drivers, some misc...

    Apple Studio Display M7649 CCFL to LED conversion

    Since the previous post, I ordered some longer LED strips that were more appropriate. The previous post used two "laptop" kits which have an inverter that only drives one strip of LEDs. The new inverters came with dual strips, so each tiny inverter drives both strips. These inverters are also...

    G4 Digital Audio and 20" (A1038) Cinema Display -- goes blank on bootup

    I could not see a picture on one of my 17" displays with a bad inverter board. The power light stayed on, but the flashlight test did not work for me either. I replaced the backlight with an LED strip and it works great. There are two boards inside the display, one is a logic/graphics board...

    G4 Digital Audio and 20" (A1038) Cinema Display -- goes blank on bootup

    So when you fully boot into safe mode, what is the resolution? Do you have any other boot drives or optical media to boot from? Sounds like a software conflict.
