LEC16 was a copy of the PDP11. Lockheed sold it to BBN. BBN relabeled it Pluribus. I was part of the DEC engineering team looking at purchasing the LEC, as one of the features was the ability to be an Arpanet IMP. I was quite familiar with t the Unibus, and noticed the print set was very similar to a negative copy of an 11/20 print set. I raised this with the boss and legal. The machine was then referred to as the Lockheed SUE. //bob
