[HECnet] Is this the most up to date version of DECnet OS numbers?

It was on the 9'th floor. There where "footsteps" glued to the floor, "the way to OZ". 

Rob Austin was sys$manager, and it was used to develop "Chives" the domain resolver, 
but it belonged to the folks on 4:th floor not 7:th floor. 

The 2020's showed up much later and was only used to run ITS.
