A recent item in the Tech Support folder ("AppleShare 1.0: Installing
with System") stated that it is OK to run System 3.3 with Finder 5.4 on a
Macintosh II.
This is emphatically not OK -- you should not run 3.3 on either a
Macintosh II or Macintosh SE.
- a Macintosh II requires System 4.1 or later.
- a Macintosh SE requires system 4.0 or later (4.1 is even better).
