[Coco] Format of DEFT.ZIP

[Alan Jones]

Robert,
Thanks for helping me learn how to do something useful today.
I downloaded "Funduc Software Hex Editor v2.0" and removed the first 80 
bytes from the begining of the disk image. Then I shortened up the end 
of the file by making it $27600 in length and I saved it as 
"DEFTMESS.DSK" so I could test it and it worked! I just checked Ken's 
website and the edited version of DEFT.DSK is available. Have a nice 
Fourth of July.
