VCC is a Coco3 emulator. It has problems with disk images that are not 
full sizes - 35 or 40 tracks - when there is data in T0S1. In those 
cases, the size of the image is calculated from LSN0 as if the disk were 
an OS-9 disk. That is why the Urbane.dsk image does not work with VCC.

What ever was used to create the disk image placed ubn_in.txt in gran 0 
and then did not populate unused sectors at the end of the image so it 
is less than a full 35 tracks.
