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.

How many 1970s era or earlier mainframes are actually up and running
(or in working condition) somewhere? I have not really followed mainframe
collecting, although I did work on IBM 370 and 30xx mainframes in the 1980s.
