简介

I have an iMac with a broken graphics card, and it seems like a waste to just throw it away, so I've decided to convert it into a monitor, and hopefully get all the accessories working. (iSight, SuperDrive, SD card reader, and Speakers)

This is a work in progress

  1. Follow teardown guide to remove logic board, video card, hard drive

    • Connect Driver Board to display

    • I got mine here. https://item.taobao.com/item.htm?id=5381...

    • Connect a DisplayPort (male) to mini DisplayPort (female) cable to the driver board and hotglue the female end to the iMac back panel

  3. (Optional) If you want to use the original iMac power button, connect the switch to the 12v latching module, PP12V_G3H + GND to power in, and connect the PS_ON pin to the output. Latching module should be configured to pull to ground when "on"

    • If you just want it to be always on and use the driver power button, short PS_ON to GND

    • Pinout guides here: Can anyone tell me what these PSU pin abbreviations mean? PSU 614-0446

  4. Disassemble USB Man-style hub, cut cables, insert USB sockets into usb openings, hot glue USB ports from the inside and solder everything back together Something like this... https://www.amazon.com/Kikkerland-US006-... you need another 5v/12v powered 4 port hub to connect the iSight, SuperDrive, SD Card Reader and the rear ports. And some donor USB cables...

    • iSight Pinout +5v = brown, D+ = Purple, D-= grey GND=black. Unfortunately Apple uses different colors for different revisions. Pinout of the iMac's built in iSight..

    • SD Card Reader Pinout +5v = orange, D+ = grey, D-= purple, GND=unshielded cable. Again, Apple uses different colors for different revisions, although you'd think the cabling color scheme would be at least internally consistent.... https://www.tonymacx86.com/threads/apple...

    • Connect the USB-SATA bridge to the SuperDrive and the USB hub. I had to cut away some plastic to fit the USB adapter

    • Power the USB hubs with the 12v pins, or use a DC-to-DC stepdown board to convert 12v to 5v. (The power supply doesn't provide a 5v rail...)

  5. You can also get the Apple IR receiver working! the first wire in the left ( marked V on the board ) is D-, second is D+, third is 5V and the last wire is Ground. https://www.tonymacx86.com/threads/apple... The Bluetooth module is also USB, but need a 3.3v line https://homokozo.czo.hu/iMac2011mod/iMac...
    • Thinking about getting the speakers and Mic working as well. We are going to need a USB soundcard and an amplifier that can handle driving the built in 17W speakers

    • DIYaudio.com seems like a pretty deep pit to jump in.

    • Do I need a fan controller? I think I need a fan controller.

结论

To reassemble your device, follow these instructions in reverse order.
