To eject a disc with Open Firmware commands, follow these steps:
1. Restart the computer.
2. Immediately after the startup sound, press and hold the key combination Command-Option-O-F.
Note: The Command key has the Apple icon on it.
3. Release the keys when you see a white screen that says “Welcome to Open Firmware.”
4. At the prompt, type: eject cd
5. Press Return, then wait a few seconds. The disc drive should eject any disc that is present, and “ok” appears behind your command when the action is complete.
6. Type: mac-boot
7. Press Return.
Your computer should now start up normally.”

between this posting and Justin’s very small weak tweasers, she was able to extract not only the CD, but also a piece of plastic mesh. I think it must have been one of the oddest things I have ever seen!
