This is an unusual item, as the packaging is the same as the more standard Topologika release, but cut off about 2/3 of the way down, to size it to just fit the 5.25" floppy. The contents are otherwise basically the same as the 'larger' release. One might dismiss this as something a previous owner did, but I have seen at least one other copy exactly like this, so that is most likely not the case.
