If you look carefully with the magnetic viewer, you might be able to see
the alternating lines in the center (due to the dual heads in opposite
polarity) which would indicate neopilot sync. It's much better to resolve
the audio upon playback so that no subsequent digital processing
(varispeed, then sample rate conversion) is necessary.
You would need a machine with special heads, and also a resolver (Lynx,
EC401, etc). Some machines have the resolver built-in, such as the
