Also, if you look at the drive in the a1200, it has a small PCB connected into the mobo for the FDD to connect to. Basically Escom ran out of amiga FDD's and started to use hacked PC ones, whilst there was still stock of the mobo, etc. If you get a Chinon drive from an a500, remove the PCB on the FDD connecter, plug the chinon into the Mobo - problem solved :-)
