About the contents of this archive:

The "large installer," v1.57h update, and scans of package and reference card were all taken from a Mac-only release of Harpoon Classic that nevertheless had packaging indicating it had been intended for a hybrid PC/MAC release.

The v1.61d update was found on the internet.

The PDF manuals were found on the internet, having apparently been taken from a PC/MAC CD release.  They are exactly the same as the paper manuals from the aforementioned Mac-only release.
