> Correct.  And a number of DEC operating systems had card reader support.  I haven’t seen them very often on DEC machines, but for example RSTS can handle at least 026 and 029 card codes, and some vague memory says there may have been a “1401” table as well.

This should come as no surprise.

We often think that DEC machines were all doing cool things like
running railroads or controlling high energy physics experiments, but
a large number of PDP-11s spent their lives running plain old business
