Font used by DEC for the PDPs

I am trying to identify what this font is exactly. It is easy to name a few similar ones, but I've had no luck finding what this is precisely. It is the font used on the old PDPs from the Digital Equipment Corporation (DEC).

I attached a sample of the font, which came from this image. Here is another image of the font albeit at a lower resolution.




There are some very amateurish elements to the execution of that (lack of optical compensation where curved strokes meet straights, for one). That leads me to think that it was not from a major vendor... could be hard to track down.
