The current DiscFerret firmware runs at 100MHz fixed,

add a clock divider to allow e.g. 50MHz and 25MHz sample rates to be
selected (which would save a bit of acquisition memory when imaging
floppy discs).
I mention this mostly because a hare-brained idea occurred to me over
the holidays. A Catweasel Mark 3 can use a sample clock of 56MHz.
Since the amount of data on a track isn't an issue, I wonderred if
rigging up a lashup with some RS422 receivers and a MK3 and some way
to handle more than 2 heads (printer port?) might be a nice rainy-
day project.
