https://pico-systems.com/stories/1969.html The PDP-5 computer was at Washington University: "We had a cast-off DEC PDP-5 computer (basically an early version of the PDP-8, all discrete transistors) in a pretty much defunct lab called the Hybrid Computer lab" https://www.computerhistory.org/collections/catalog/102621969 "Gift of Washington University in St. Louis" |

This is a point-plotting display in the same vein as the PDP-1 Type 30. You can set X and Y in the range 0-1023, and optionally "intensify" i.e. plot a point there.
The PDP-5 "ICBM" game by Len Berger is supplied as a test.
The IOT instructions for the Type 34 display are documented here:
