MACL vs system 7.0

[Massimo.Bigliardo@SAM.CS.CMU.EDU]

I am going to use your MACL networking program with Allegro 1.3.2 on appletalk.
Some machines on the net are being upgraded to the System 7.0.
Do you know about any compatibility problem with it? 
I had a "bus error" message after ADSP networking application was loaded,
when I was trying to create a client on the virtual MAC2 (as reported in the 
sample-session.text).
Thanks in advance
