HI ..this brings old memories ...well.the only way possible is to use an old ISA (8 bits ) floppy controller ..beacuse the floppy drive only outputs MFM format data ,to get binary code ,that requires complicated demodulation that is done in the floppy controller .In other words the floppy controller is not just a bunch of registers to hook to the ISA bus ..is also a big part analog .. and the other half of the floppy subsysem drive ..
IS not over !..then you need a disk structure to store data ..i mean a format
by the time you are done ..you will spend too much time .adn is a knowledge that is OBSOLETE ..you won't be able to use it in any thing,...look at me ..i use to do this type of designs ..and now nobody ask me to do it anymore ..
