"The RX50 floppy starts at track 1. Track 0 is logically placed after
track 79. The sectors are interleaved 1, 3, 5, 7, 9, 0, 2, 4, 6, 8,
10. The track shift and interleave must be taken into account when
moving disks between real PDP-11 and emulators."
Let me point out that this webpage quote accidentally lists too many
sectors for an RX50.
It should be "... interleaved 1, 3, 5, 7, 9, 0, 2, 4, 6, 8..." There
is no "sector 10" when counting from 0.
