That was Technology Concepts Inc, Sudbury MA. Sometime around 1984 I
almost left
DEC to join TCI but then had a change of heart. Sun’s DECnet
implementation was
either done by TCI or based on their code.

I worked at a customer site in Sweden which consisted of a pair of
11/40’s running
RSX-11D and DECnet Phase I. I’m pretty sure that Phase I only ran on
11D in the RSX
family.
