UGHHHhhhh!
It probably will, IF you run it off a floppy _after_ a full powerdown that never loads a byte of windows, otherwise windows blocks access to the hardware and returns no clue to the user that he has been blocked. There was a setup program for calibrating the servos in dvc-pro recorders whose output needed to be displayed on a minimum of a 4 channel oscilloscope, and it was dead in the water if it wasn't run by doing a cold boot to the floppy it came on.
