I've got a boot disk, that has AZ and one of the older versions of Diskmaster2, and its been a life saver on a few occasions.
I haven't used it in a long time, (I think it was powerpacker?) but when I had an A500 with a small HD, it was to unpack executable programs in order to save space. Would something like that work with programs on a floppy? It might with a TCP stack at least.
