I'd forgotten about that -- so I just had a look.  It should be enough to
understand the ADFS implementation for "L" format floppies, especially
given a real ADFS disk to play with, but it's not enough to use with
winchesters that might be partitioned to have Econet File Server stuff, or
CP/M.

It's also not sufficient for later formats used by Archimedes machines,
like "D" or later formats, or partitioned RISC iX disks, but that obviously
wouldn't matter for anything on a Beeb/Master :-)
