[Coco] Rainbow cassettes

[Robert Gault]

If your tape version of ZAXXON is anything like my disk version, it is 
highly copy protected. So, if you are trying to convert it to disk, I 
expect you to have much trouble and it may not be possible.

Here is part of the copy protection on the disk. Many unreadable sectors 
so the disk can't be backed up. The directory track is partially 
unreadable so the DIR command does not work. The loader is on track 34 
so that either the DOS command or a short Basic program that simulates 
DOS is used to start the game. The sector values extend to 31, making 
many good sectors unreadable by stock DOS1.0 or 1.1.

There is probably more copy protection because the loader I looked at 
fills every other sector of memory from $3CA0 to $7E00. There almost has 
to be a second loader that fills in the missing alternate sectors.
