Thanks for the last two replies.  I am not understanding completely.
A difference in ATalk packets I can understand.  Why do the iMacG4(s)
show up as available file servers in the IIGS Appleshare cdev if the
ATalk packets are different?  Failure comes at the login attempt where
incompatible atalk would cause problems.  But why does the server
appear if atalk is not working at some level?
