Re: Looking for a couple of On-Line Systems disk images...

These are 5.25" disks.  I believe the file system is DOS 3.2 (these are
from early in the A2's life cycle).  I tried using the disk
verification option in Copy II+, and it gave a track error for every
track.

ERROR TRACK $00
SECTOR $0 1 2 3 4 5 6 7 8 9 A B C D E F

And so on for each successive track...

That's a 13-sector disk, so you'll need to bit-copy the disk.

Since that was very early, it's likely that any protection
is pretty simple.

BTW, your 16-sector can read the disk fine, but if you want to
*boot* it, you'll need to pre-boot BOOT13 from the system master.

OK, Locksmith didn't work.  Does anyone have any insight into how I can
copy this disk?

Getting through copy protection is a really fun game!  Some are easy,
and some are devilishly clever.

I don't know what kind of disks these are--5.25" or 3.5"--or what
file system is used:  DOS 3.3, ProDOS, or "other".  That often
gives some guidance about likely protection schemes.

When you attempt a "disk verify", what result(s) do you get?
