Does anyone know how to convert a block position on a diskette to a
track/sector notation?

In Beneath Apple ProDOS, they have a table for converting from track/sector
to block numbers (on page 3-17).  Then there's another table in the July 1985
issue of Open-Apple (page 55) that gives track/sector to block conversions,
which differs slightly from the one in Beneath Apple ProDOS in that it
doesn't use physical disk sectors (Beaneath Apple ProDOS's chart does).

   A conversion chart is part of the reference "Beneath Apple Prodos" by
Worth & Lechner, published by Quality Software.
