Problem 1 - Blinking folder, question mark, grey screen. This could probably be fixed with the install disk if it weren't for ...Problem 2- how do you open the CD drawer on an unresponsive old iMac? I was almost ready for a prying butter knife, but iBrain said "Don't do it, fool." Any ideas? I love my old Mac.

    There are a number of posts in this forum about defunct iMac G4's this day.

     

    You iMac could not find a valid os on a harddrive. Probably hd has gone bad. Hd last 5 or so years  on the average. Your HD has been good to you.

     

    What to do. 

    Try holding down the option key then power on. This brings up the startup manager. Click on your hd. Click on right arrow key.

     

    Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:

     

    reset-nvram

    set-defaults

    reset-all

     

    "The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

    http://support.apple.com/kb/TS1812?viewlocale=en_US

     

    No luck.  Re-install OS

     

    Install new hd.  PATA.

     

    Buy external hd.

     

     

    Eject cd.

    power off your machine.  hold down your left mouse button.  power on your machine.  This should eject the cd.

     

    On a PowerPC-based Macintosh (but not an Intel-based Macintosh), you may use Open Firmware to eject a CD or DVD disc when normal methods for ejecting it have not succeeded.

    Immediately after the startup sound, press and hold the key combination Command-Option-o-f. Enter commands:

    eject cd

    mac-boot

     

     

    external hd

     

    You need an external Firewire drive to boot a PowerPC Mac computer.

     

    I recommend you do a google search on any external harddrive you are looking at.

     

    I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient. The Oxford line of chips seems to be good. I got the Oxford 911.

     

     

    Has everything interface:

    FireWire 800/400 + USB2, + eSATA 'Quad Interface'

    &

    save a little money interface:

    FireWire 400 + USB 2.0

    This web page lists both external harddrive types. You may need to scroll to the right to see both.

    http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/eSATA_FW800_FW400_USB

     

    The latest the hard drive enclosures support the newer serial ata drives. The drive and closure that I list supports only older parallel ata.

    A blue screen with a circular "Reload" type of arrow, and a arrow to the right opened.

    That's the startup screen.  That's what happens if the firmware ( software ) cannot find a device to boot from.  It looks for a bootable os & if it cannot find a bootable OS no icon will be displayed.

     

    As far as the cd commands, the eject cd command gave me an error message, of sorts. Something to the effect of "not a valid command or command not understood".

    Not sure about this.  Try these other commands.  maybe it's eject dvd

    maybe it's:

    eject dvd

     

    the "cd" should appear in the list of device, i'd think. Try what's close.  What about the left mouse button?

    How to eject a cd from the internal cd drive:

    eject cd

     

    List of devices:

    devalias

     

    List of variables:

    printenv

     

     

    I'm hoping to possibly reboot with the original install disk attached by USB in an external drive.

    No!  ( highly unlikely,  Boot from a USB device is only supported for a few PPC computer. )

     

    You need a firewire cd/dvd drive.  Can adhock a cd/dvd drive into a firewire hd.

    sometimes there is a small hole to the right of the dvd/cd slot (inside the slot) that can be pressed with a paper clip. 

     

    All the ways of ejecting.

     

    power off your machine.  hold down your left mouse button.  power on your machine.  This should eject the cd.

    Time to learn about hardware repair.  You might try duck tape on the cd.  Once you take the machine apart, you will be able to get closer to the cd. Might give you more leverage.
