I am trying to setup another computer that should be able to read pc's 
floppies.  What I need to know is the various hardware programming 
parameters for the pc's floppy chip (uPD765).  I am using the same chip, 
and the data sheet says nothing about the various pc formats.  Does 
anybody have this necessary information (gap length, etc.).  I have 
deduced some of the parameters (sectors per track, tracks) but need a good 
table of specifics for 5 1/4" 360k, 5 1/4" 1.2meg, 3 1/2" 760k, and 3 1/2" 1.44meg formats.  If there is sufficient intrest, I will post as well.

If anybody has a driver for the small cartrige tapes that run off of 
floppy controllers as well, that would be helpful too.

Thanks for the help.
