I'm impressed that you were able to find leroy! I just did about fifteen minutes of searching online and was unable to find it. If you wouldn't mind, could you share it with us? I'd enjoy playing with it. It's on the 1981 Usenix tape, in the ucol directory: https://www.tuhs.org/Archive/Applications/Shoppa_Tapes/usenix_81.tar.gz It looks like leroy produces output for an "extended" form of plot; from the docs: --      The plot stream leroy emits is intended for,  and  must be directed to, an extended UNIX plot filter.  These filters recognize a number of commands not included in  the  vanilla seventh  edition  filters,  mostly  dealing with the Hershey fonts.  The extended plot filters are upward compatible with their  predecessors  and  have been implemented in a fashion which makes tailoring new devices filters very  straightfor- ward.   The  source  code  is available on request. Filters currently exist for the Tektronix 4014,  the  Versatec,  the HP7221A, and the Qume. -- -Henry I realized that UCol was using a PDP-11, not a VAX, so I switched to running things under Ultrix 3.1. Using the extended plot libraries that UCol provided on the usenix tape, I was able to get Tektronix 4014 output which I was able to run through a modern tek2plot.  Here are links to the raw plot file and an SVG, which I think is most useful for this sort of display. https://drive.google.com/file/d/19mdAYvjlAq7qp5KyJWQrgMwefOfq7XuC/view?usp=… https://drive.google.com/file/d/1tX7Qclk-1V5BOrXWKP0bZouf6PoZ3KlK/view?usp=… -Henry
