What is it?

OpenAmigaDriveSwitcher is an Open Hardware adapter that can make the first external floppy disk drive (DF1:) on an Amiga 500/500+ appear in place of the internal drive (DF0:).

It also works on an Amiga 2000, however note that DF1: is still an internal drive on this computer.

Why did you make it?

OpenAmigaDriveSwitcher turns out really handy for people using a Gotek floppy drive emulator who don't want to mount it internally. In fact, this requires some case modding, both for fitting the drive and for making it useable, as having a display on the side of the Amiga is quite uncomfortable. Connecting the Gotek externally will not work out of the box for most games as they assume they are running on DF0:, which was the only bootable drive back in AmigaOS 1.x times.

Keeping a Gotek drive external also allows it to be used with different computers.

OpenAmigaDriveSwitcher comes as an adapter PCB that sits between the Even CIA chip and its socket and can make the external drive appear as DF0:. However, it does not fully swap the drives, which means that when it is enabled, the internal drive just "disappears", it does NOT become DF1:.
