[comp.sys.mac.system] Sys 7 backward compatability

minich@d.cs.okstate.edu (MINICH ROBERT JOHN) (06/12/90)

  Does anyone know what efforts are/could be/will not be/[generic]
focused toward making Sys 7 goodies compatible with machines running Sys 6.x?
The first things that come to my mind are aliases and file id's. If I
use these features on a disk, what will happen when I try it with an
older system? I assume aliases will just appear to be garbage as far as
programs are concerned. Is it likely that an old Finder/System will
screw up data structures on the disk? (I guess a nifty solution might be
to flip the write protect tab so nothing can be messed with, but that is
not the friendliest thing.)  
  A whole other area is file servers. Do they need to know anything
special? Is it reasonable to expect to have machines running 6.x and 7.x
using the same file server AND getting maximal functionality out of it?
Inquiring minds want to know.
