PS. The floppy drive appears to work fine on my A1200 with the switch in the original position as shown in the photos.
I've had three external drives daisy chained to my A1200 many moons ago (until I flogged one of them). Your drive should/will work fine with the switch in position 0 as it (confusingly) corresponds to external drive 0 (i.e DF1) and not DF0 as you'd expect.
The 15/9 pin adapter looks like it is intended for use with a PC joystick of the type that would have originally plugged into the midi/gameport.
