I waited a bit before chipping in, as I think Paul would know more.
The ATCP stuff was in at least a few vendor branches, but I don't think
it ever made it into the main distribution. These commits seem to be
where the (disabled by default) references to it first appeared:
commit 50c9469f0f683c7bf8ebad9b7f97bfc03c6a4122

add defs for appletalk
commit 01548ef15e0f41f9f6af33860fb459a7f578f004

connect time stuff gone to auth.c,
don't die on EINTR from opening tty,
ignore NCP packets during authentication,
fix recursive signal problem in kill_my_pg
The disabled-by-default parts were likely support contributions for
those other distributions. (Very likely in BSD.)
I would've thought AppleTalk was completely gone by now, and I certainly
would not be sad to see the dregs removed from pppd, but there was a
patch release on the netatalk package just last month, so what do I know?
(The only possible reason I can see to keep any ATCP bits around at all
is to make sure we can write nice-looking log messages -- to say we're
rejecting "AppleTalk Control Protocol" rather than "unknown 8029." But
that'd be a very minor feature.)
