There were several reasons why there was never a STANDARD
5.25" CP/M
format. I once had the opportunity to ask Gary Kildall
what the
standard would be for 5.25". He replied, "8 inch single
sided single
density". I repeated, "Yes, but waht about 5.25"? He
repeated, "8 inch
single sided single density". I understood, but was not
much enlightened.
I was just digging in to old CP/M a bit and it was/is tied
mostly
to the IBM 8" standard floppy and the floppy interface
used at the
time. Even that gave a very small amount memory per track.
