Looking for '8a1' message handling protocol

[Walter G Horbert]

As I understand it, there exists a message handling protocol for
police networks called 8A1 that runs under Unix.  The local Public
Safety people have acquired a 3B2, but can't seem to track down a
copy of this for AT&T Unix.  If anyone can help point me to
sources or equivilents, it would be much appreciated.
