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.
It was fairly easy to make CP/M work with other disk types and formats. Even **I** was able to write a driver to add a SASI Winchester drive to my CP/M system. (That made it run SOOO much better!)
