Looking for a floppy image of a blank 1.44 floppy which includes all
header and gap information.


The data *** for National Semiconductor's PC8477 controller chip has
this information, in Fig. 4.1.

See http://www.winbond.com.tw/PDF/APC***/PC87338_PC97338.pdf table
3-12.

Gap 4 is not a written gap, it is the remainder of a track when all the
sectors have been written and as such will depend on the speed of
rotation of the drive.
