Good stuff! On the A1200, the floppy LED is connected to the /MOT signal, rather than indicating actual read/write operations. Does it not show any sort of activity at all? I modified drives before to show the same type of activity by connecting the LED with a suitable resistor directly to the /MOT signal at the drive's 34-pin connector. In that case, the positive side of the LED is towards 5V and the negative side is to the /MOT signal.
