My best guess is that maybe you have a 13-sector (DOS 3.2) disk
controller and one 13-sector disk (the one that works), and the
rest of your disks are 16-sector so the 13-sector controller
doesn't know what to do with them. Unfortunately I can't remember
where to peek to find out the DOS or controller version number,
so I don't know how you could verify this.

The other alternative is that if your Apple II+ has less than 48k
of memory, the other disks may be expecting a 48k system and loading
DOS into a part of memory that doesn't exist on your computer. The
Zardax Utilities disk may be one with a relocatable DOS image on it
(a "master" disk) created with "MASTER CREATE" and the rest are just
plain fixed-address disks. This would certainly explain why random
junk was getting loaded into video memory instead of where it belongs.
