Hey Neal,
Yeah, I could see that scenario play out to a sad end!
Personally, I think those tape would look really nice sitting on the shelves next to the Monterey Jazz Festival tapes at the Stanford music archives (Braun Music Center).

But, for those of us in the Bay Area, they have kept the Ampex sign (which is on Stanford's property) so all of us can see it on our way down the freeway.
