That's later then I would have expected - I could have sworn that Phase IV was out by then. Actually by the fall of 84 I was working at DEC and I'm sure we had Phase IV on VMS by then. Do you know when Phase III first shipped? That sounds very surprising. DECnet Phase IV was introduced in 1982, and RSX was at the initial launch. Are you sure about the date, and that it's phase III only? Phase III was introduced in 1980. Johnny
