In my quest to use 1.44MB 3.5" floppy drives on my Ampro, I've found that
the 1772-02-02 variant of the floppy controller chip can be "overclocked"
to 16Mhz in order to correctly read/write 3.5" high density disks.
Beyond needing to adjust the step rate to 6ms to compensate for the
doubled clock rate, is there anything else I should be aware of? I've
seen many mentions of this particular hack on the Atar ST line of
computers to achieve the same goal, but I wasn't sure if there was some
other factor I had to be aware of.
Thanks all!
