Is it possible to make a external disdrive into DF0?
As I recall, I don't think it's as simple as connecting your DF0: drive to the external port (with the appropriate cable made up) because the drive select 0 line _SEL0 is only present on the internal floppy connector, not the external one. Therefore you'd need to perform a couple of PCB level modifications if you wanted to make it work.
Refer to this
A600 schematic and you'll see what I mean.
