[Coco] 3.5" Floppy format

[Theodore Evans (Alex)]

Personally I feel that the "96 tpi" bit (bit 1 of byte $10 of LSN0) 
should be set.  Here is my reasoning:
   1) It would be best if everyone uses the same format to avoid 
problems.
   2)  No user uses a 3.5" floppy drive which is other than 135 tpi  so 
there is no need to have it set for one type and cleared for another so 
that the head can double step allowing the higher track density drives 
to read disks for the lower density ones.
   3) Having the bit set allows 720k 5.25" disk images to be identical 
to 720k 3.5" disk images.
   4) It allows the strict disk copy commands to copy back and forth 
between the two should a user have both on his system.
   5) It allows lazy people to use the 5.25" 720k floppy descriptors 
supplied with some CoCo distributions of OS-9 for their 3.5" 720k 
floppies.
