My guess is it was a figure in this article: https://www.computer.org/csdl/magazine/an/1988/04/man1988040277/13rRUxZRbrm https://www.computer.org/csdl/magazine/

Edit: Confirmed, kind of. A similar but different picture is figure 9: https://www.semanticscholar.org/paper/A-Historical-Overview-of-Computer-Architecture-Smith/753330481b1ede5733f48ddda3e616707a796cdb/figure/10 https://www.semanticscholar.org/paper/A-Historical-Overview-... It looks like the picture slated for figure 11, that made it to the CHM archives, didn't actually end up in the article.

This photo, also in the CHM archive but not digitized, is probably of the same layout / computer: https://www.computerhistory.org/collections/catalog/102757910 https://www.computerhistory.org/collections/catalog/10275791...

  The title attribution poses another riddle: "PDP-1/B and miniature model railroad at University of Massachusetts". The PDP-1B was the production prototype of the PDP-1 and there were only 2, we know of. The first one (white) was intended for LLNL, but the order got delayed and it went to BBN instead, the second one (blue) became the actual LLNL machine. Update: Curiously, the this page [1] also mentions a "PDP-lB" [sic!]: [1] https://www.cics.umass.edu/about/history-school-computer-science https://www.cics.umass.edu/about/history-school-computer-sci... Anyway, this seems to confirm the Amherst link already suggested by Steve Russell.

    Good article... it points out that J.A.N. Lee was appointed Program Head of the new CS program at UMassAmherst in September of 1964. And that is the same person whom the 2nd photo was from in the thread’s main article.

That does look correct, great find. Unless things have changed it would be unusual to refer to the University of Massachusetts as UM. I grew up in MA and have only ever heard it called UMass. It's possible it used to be called UM before they expanded it beyond Amherst and Boston.

Thank you very much, I will update the article accordingly! Edit: Updated! – Now a legit HN success story. :-)

The article, without the paywall: https://sci-hub.se/10.1109/MAHC.1988.10039 https://sci-hub.se/10.1109/MAHC.1988.10039 It downloads very slowly, for me. Be patient. UPDATE: literally 56KB/s, and 34 megabytes. The fastest modems used to be 8x slower that that!
