HPIL models), but of course there are many other machines.
I wonder if increasign the write current would help. It should only be a
matter of changing one resistor.
Modifying the drive to use the other diskettes should work.
Would that be an increase or a decrease in the current?
But, you should keep a convenient way to switch back when using real DD
diskettes.
