Almost exactly. Actually, it was an accident. It was obviously a 40-track
flippy to start with, and at some time in the dim and distant past I must
have decided to use it "properly", two-sided. But only the second side had
been formatted in the flipped orientation, so although it was 40+40=80
tracks on one side it was only 40 on the other.

This can't
be possible! Otherwise, why didn't someone exploit this to
make 4-sided diskettes??
Because you don't gain any extra storage. Pete formated every other track
on the disk using an 80-track drive (narrow heads). So in the end he had
80 tracks on each side (40 going in each direction). Since an 80 track
drive can write 80 tracks anyway, there's no advantage in flipping the
disk over.
