So does that mean that RTS/8 DECnet Phase I was built but not shipped? Or shipped but not supported? The document I referred to is a full manual "RTS/8 DECNET/8 User's Guide, Order No. AA-5184A-TA". A note at the start says "converted from scanned text 1-Jun-1996" and just below that "First printing, February 1977". Chapter 6 is a fairly detained description of protocol message formats, which look vaguely like NSP as we know it but only vaguely. paul
