I have been reading through threads but not managed to solve this "gremlin"
I have opened the iMac G4 and the CDRom opens the caddy when you press the manual eject button. Thus mechanism works. Also drive spins up when you insert media.
"eject cd" in Open Firmware does not work.
Just got hold of the following in full working order:
IIfx with Radius Thunder IV GX 1600
HP Deskjet 550c with AppleTalk
2 x Mac Video adapters 8/32 RevB
2 x Macintosh II adapters
2 Apple Color Monitors
1 Apple LC monitor
I just finished recapping my LCiii and obviously did not do a great job!
When I power on I hear the boot chime and then immediately I hear some of melody in the form of chords...3 going up and then 3 going down.
No video signal.
Fitted in a G4 Power Mac (Quicksilver) on a 20Gb macOS 9.2.2 partition, downloaded s/w 3.4.2 from http://www.vintagemacworld.com/omweb/HowToUpgrade34.html
