To everybody looking for a little fun coding challenge for the holidays.
I am playing with an ancient 3.5 inch floppy drive in my latest hacking project. I have sampled a track from it using a logic analyzer. I have also hacked together a little script last night to find the MFM symbols.
Now the fun part can start. Getting data from the MFM stream, decoding track and sector headers, ... Low hanging fruit!
