There were several reasons why there was never a STANDARD 5.25" CP/M

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.
