    Since non of those can run MorphOS out of the box I doubt that ever to happen.

    Isn't this the same as with eMac and PowerBook G4?

    ? All I changed was my video card, and my quad is running MorphOS fine (I still need a network or wireless card). 8 GBs of memory (w/ >6 going to waste), but no problem leaving it all in place. I did have trouble trying to install a CMI based audio card and a SiI3132 PCI Express SATA controller card, but I'll try those again now that I have it running.

    Not enough expansion slots and they are too close together (wide video cards cover the nearby slot).

    Hi there, why does the G5-20" work and the G5-17" 1,9Ghz (x600pro) not?
    What hardware is the problem on the 17" model? Thx

    There are subtle changes between the models and even production runs of the same model. We've had enough of the hardware to look into the 20" but not the 17".

    inspired by zukow thread about powermac G5 here is some info about MorphOS 3.12 on unsupported iMac G5/2.1 (PowerMac12.1):



    Ran into really cheap same iMac G5 model and happy to report I am typing this from Wayfarer

    So far very elegant and nice experience with MorphOS 3.15 and Crysalis, thanks to everyone involved.

    Yes, support (unofficial) for the 17" A1144 would be useful. I can get good buys on these, and I'd like to avoid rebuilding the coolant system on my G5 quad for awhile.

    Get some of those and send at least one to MorphOS team - then there might be a chance ...The only reason there is unofficial support for the 20" isight one is that I got hold of one quite some years ago and didn't want to keep it in the closet forever ...

    But seriously, we have plenty of machines supported already. We really don't have plans to expand the range even further. While it looks like some machines are just a (down)scaled version of some other model, it doesn't always scale that well on the software side of things and needs considerable effort to add support.

    I just got a 20 inch iSight imac g5 it works very well
    I wanted to know if it was possible to connect the mini vga socket to an external monitor with an adapter
    I have a pc monitor and I would like to use it on the mac not having the space
    the mini vga connector works only with mac os x or also works with morphos by connecting it to a simple vga monitor / display port / hdmi with adapter +

    Another question is it possible to disable the sound when starting the mac by unplugging the speaker connector maybe
    Using it in the evening every reboot is a problem for people who sleep
    I also have a macmini and I unplugged the speaker

    There is no need to disconnect the speaker. Just open MorphOS Preferences/Sound and set the "Startup sound" volume to 0.

    An adapter like this could work with Morphos?
    For a matter of space I need to use the PC monitor
    The issue will work on Morphos and above all the Mac monitor if I connect an external monitor will turn off?
    Has anyone tried to do it?
    Let me know, thanks

    That adapter came with the iMac when it was new, so it for sure should work.


    I do have one on mine and use a 2nd monitor with it under MorphOS but I'm not 100% sure what you want.

    You can define2 screens and have certain apps open on the 2nd one (like I do)

    You can force Ambient onto the external display and leave the builtin unused (or use that as 2nd display)

    There is AFAIK no way to make both screens show the same screen (mirror) with MorphOS

    If you want to use it under OSX in anything but mirror mode you need to apply a firmware patch.

    I want to use morphos on a monitor that I use for pc
    the mac would go behind the pc monitor because i don't have space on the desk
    if I connect a second monitor to the mini vga socket, the main monitor of the mac TURNS OFF? can you turn it off?

    I have a 20 inch isight imac g5
    I don't have much space in my workstation the only solution would be to put it behind the LCD TV
    If I connect the mini vga socket to my pc monitor that I use every day, would morphos work?
    Could it work if I unplug the imac lcd monitor by unplugging the connectors?
    Using the mini vga of course
    In theory it should behave like a laptop
    Has anyone tried this?

    If you really want to do something like this, it would likely be better to disconnect the internal panel and route the DVI signals out of the box - the internal plug is actually a proper DVI, which will go up to Full HD resolution easily.

    (edit: to be precise, it's not a DVI plug, but the signals are the same)
