Hey 1time,
Old disk collections like that are always worth preserving in .ADF format!
I can't see that any of those disks will have copyright issues after all this time, so please go ahead and make images of them.
I'm sure that they will find a good home on the EAB file server.
TCD will tell you more about that when he finds this thread.
Finally, thanks for offering to preserve your collection for the Amiga community!
