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). jjl@ocf.berkeley.edu
