It originally had a paper tape reader punch, which was removed to an IBM 1627 plotter, a version of a Calcomp plotter. I remember that you could plot from Fortran using the PUNCH PAPER TAPE instruction. We had a lunar orbiter game which used the plotter and the four sense switches on the 1620 console to turn thrust on and off and control it's direction.</div><div><br></div><div>The EE grad stunts coopted the paper tape reader punch and attempts to interface it to the PDP-8 with plans to use it for a paper tape OS. As I recall they got it far enough to be able to start and stop the beast, but gave up because they couldn't figure out how to slow it down so that the data rate was slow enough for the PDP-8 to consume.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Mar 4, 2020 at 3:35 PM Pete Soper <<a href="mailto:pete@soper.us">pete@soper.us</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div dir="auto">French to Googlish: "IT SEEMS THAT THE STRIPS OF PAPER ARE BLACK"<div dir="auto"><br></div><div dir="auto">The strangest paper tape episode I had was coming into a Uni lab after a weekend to find an ASR33 bolted to a wall below the ceiling.
