Yeah, that latter is the one we're looking for (mostly).
I was able to download a version of that one that worked but I don't
think I like the results. One problem is that the instance of the font
I found didn't have a bold face version. You can see the results here.

The name of the font translates to "Bold Extended". DIN 1451 is a family of
fonts, see Wikipedia. You're looking at one of the members of the family, the bold
wide one. It's not all that bold, judging by the pictures; if you need something
bolder still you may be out of luck.
That also suggests that the DEC font isn't this one. Could it simply be Helvetica?
... I just posted that the closest I know of off the top of my head is
Akzidenz Grotesk. (Indeed it's not DIN.)
