Can anyone help me with the AppleTalk hierarchy and how it
relates to the ISO model?

This is roughly what I got from Bob Denny's article in MacTutor
of 11/85:

    1.	Physical	SCC, AppleTalk Personal Network, PhoneNet
    2.	DataLink	ALAP
    3.	Network		DDP + RMTP
    4.	Transport	ATP  (NBP?)
    5.	Session		AFP (Denny didn't mention it, since it didn't exist)
    6.	Presentation	(none)
    7.	Application	LaserWriter driver, any Mac program

The acronyms are
	AppleTalk Link Access Protocol
	Datagram Delivery Protocol
	Routing Table Maintenance Protocol
	AppleTalk Transaction Protocol
	Name Binding Protocol
	AppleTalk Filing Protocol (brand new)

These are handled by the software
	DRVR '.MPP': ALAP, DDP, RMTP, NBP
	DRVR '.ATP': ATP
	AppleShare: AFP

Did I screw up or miss anything?  And just out of curiosity, where does
the Kinetics chop it off, at Level 3 and below?
