No, not backwards.
Exxos should the 920 work on any other machine? will it work in a TOS 1.0 or 1.2 ST? just as a 720k drive? If it should then I have managed to break the drive.
I cannot get the H5c1 to read any floppy drive now. I am not good with an oscilloscope yet, but I am understanding.. I just dont know where to start looking. Thanks
