Since this list has a number of people that are very knowledgable on the subject : Am i correct in thinking that, given a custom FDC, i could run a modern 1.44 floppy in FM mode, and at much lower data rates i.e. (say 50 KHz.) ? Background : I am musing on how to give a small amount of storage, say around 100kb, to a very small low tech cpu. I do not care about speed and efficiency. I am aware that IDE-based solutions are simpler, both hard- and software wise, but I would prefer a floppy based solution. Jos Dreesen
