Indexed by the low six bits of a note byte (PLAY_NOTE): the first two bytes are the B and C counts that time each half-wave, the third how many waves make one unit of length. Row 0 stands for a rest and is never read.
The same 183 bytes as Knight Lore's note table, and so the same scale: a semitone a row for five octaves, G#1 at row 1 and A4 (440Hz) at row 38, with the timing drifting a little sharp at the bottom and flat at the top, and row 18 a copy of row 17's pitch where C#3 should be. The comments are that table's, worked out from the loop timings at 3.5MHz.
