The Phase IV specifications date from the early 1980s and the Phase III
specifications appear to be around the 1980 mark (at least for Session
Control). That would make Phase IV a good number of years younger than
VMS itself but I don't know when Phase IV actually became available
for VMS.

Thanks. I suppose the next question would be when was DECnet added to
the base VMS installation kits. Was that with VMS 5.0 and the LMF ?

I'm trying to understand how long DECnet Phase IV, as we know it
today, has been in existence.

Thanks,

Simon.
