Amiga A3000 Floppy Eject for A500/A2000 Floppy
This is a weird one!
Let's assume you have a Amiga A500 Floppy Drive (Chinon FB-354) and want to make that DF0: in your A3000. The metal base for the eject button is quite different to the Chinon FB-354 Rev A which normaly goes behind the A3000 front plate. But this will give you a chimera A3000 floppy eject button to fit to your A500 Chinon.
