In the referenced article, Dave Hawkins is mentioning our policy towards
upgrades of the Magic Sac (64K -> 128K ROMs).
  Dave is running into a problem that's really based in our trying to
explain to users the differences between 64K and 128K ROMS. The big difference
is the HFS file system, which is supported for 64K ROMs (and thus the
Magic Sac) by "Hard Disk 20", a sort of RAM-based HFS patch from Apple.
The other differences, such as zoom boxes, sped-up Quickdraw, rom-resident
routines, and so forth found in the 128K ROMs are not supported by the
Magic Sac. The HFS support is what is meant by "will be made up in software".
We didn't mean to confuse anyone, it's just very difficult to explain
HFS, MFS, and HD-20 to a casual user.
  We haven't done any work on a 128K ROM version Magic Sac; our present
efforts are towards IBM PC cards that read/write Mac disks.
  I hope this clears up any confusion we might have caused.
 -- Thanks, Dave
