Cassette load preparation card
Representative home-computer practice, 1982–1988
Observed surface
Rewind to the labelled counter position.
Clean the signal path only with the equipment powered down.
Begin playback when the computer announces it is listening.
Implied procedure
Keep the recorder level and leave its controls untouched while data passes.
If the load fails, note the counter position before rewinding; the failure may recur at the same damaged interval.
Interpretive residue
The user prepared two machines and aligned their timelines by hand.
Success depended on an ordinary audio transport behaving like a precise storage device for several uninterrupted minutes.
