Anyone have any ideas on interfacing a PIC to a floppy disk
controller?  I'm working on a project where there will be a substantial
amount of battery backed static RAM holding user data.  I'd like to have
removable storage so the user can easily load multiple sets of data.  For
interface simplicity, I'd have a load button and a store button that
would read or write a single file to a 3.5 inch floppy.  I have some 8086
code for dealing directly with floppies (without going thru BIOS), but if
someone has already done it with a PIC, it'd be nice to not have to
reinvent the wheel.  Also, what is anyone's favorite FDC?  It looks like
the original NEC 765A requires an external PLL, which I'd like to stay
clear of.  Something like the National 87311 moves the PLL onto the chip,
but also has IDE, UART, and parallel ports I don't really need.
