Sequential tape load trace
Reconstructed home-computer load
Observed surface
0000–0189 leader tone / listener acquires timing
0190–0264 header / program name reconstructed by decoder
0265–4120 data advances with no random-access shortcut
Implied procedure
4121 brief amplitude loss / confidence falls
4122–7398 data continues; outcome remains uncertain
7399 final check does not agree
Interpretive residue
RESULT LOAD FAILED / rewind required
The decisive error occurred near the middle; the user's knowledge of failure arrived only at the end.
