out of curiosity, I did a search for "magnetic tape"
in CBI's search engine. While there were several hits
on documents describing various aspects of magnetic
tape, there were no indices for any tapes themselves.
Unfortunately, the companies whose archives are being
turned over to CBI, The Computer History Museum, etc.
saved the manuals and the photographs, but none of the
software. :-<
The only exception I've found so far was in the DEC
archives at CHM, which has one storage box of PDP-15
diagnostics on paper tape.
