Cassette library borrowing card
Representative home-computer club practice, 1980s
Observed surface
TAPE C-14 / SIDE A: three programs / SIDE B: utility collection
Counter positions are approximate and differ by recorder.
Previous borrower reports second program loads only on the slower copy.
Implied procedure
Borrower records successful counter position, attempts, and any audible damage.
Return rewound to the beginning, not to an individually useful position.
Interpretive residue
The card maps sequential media through accumulated human experience.
A number on one recorder becomes a story rather than a universal address when the cassette moves to another machine.
