OT: Harpoon on the PC

I play Harpoon (sometimes).

I got involved in the game because of Tom Clancy's "Hunt for Red October" and
"Red Storm Rising" books (IMHO 2 of his best). He used the Harpoon material
for technical resource and playing out the possible out comes of certain
conflicts. Plus because Larry Bond (creator of Harpoon) was a good Naval Intel
(smart belly buttons?) Officer and also writes good books (got them all).

I've seen the Harpoon computer simulation game but never got the chance to buy
it while it was out. Is it old enough to be available for downloading off the
web? Know the URL?

Or is there someone out there who would be willing to allow me to hold a
backup version of the game for them? Er... Just for archive reasons only...
Ahhhh... In case the person has an earthquake or fire or their house gets hit
by a meteor or something... Then they'll still have an easy access to the
game.
