which *Ampro* are you talking about, and how did you
manage the overclocking? If asked, I would have
suggested, from memory, that the LittleBoard/PC
already supported high density floppy drives, but I
could be mistaken.

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!
