Apple 400K external drives will not work with any Macs that have a newer
processor than a 68000. They work on the original (128K) Mac, the
512K and 512Ke, the Plus, SE, and maybe the Classic.

The drive requires a PWM motor control signal that later Macs do not

The 800K and Superdrive (FDHD) do not need this signal.
