• What Were the Differences Between Symbolics Genera and Xerox Interlisp-D asked by Simon Brooke in Hacker News
  … I’m curious about the similarities and differences between Symbolics Genera and Xerox Interlisp-D. Why is Genera more hyped than Interlisp-D? Unlike Genera, which is proprietary and is extremely difficult to obtain legally, Interlisp-D is now free, open-source software, and there’s a community that has ported Interlisp-D to run on top of modern operating systems.

• Reviving Interlisp With The Medley Interlisp Project posted to Hackaday by Maya Posch
  Within the Artificial Intelligence and natural language research communities, Lisp has played a major role since 1960. Over the years since its introduction, various development environments have been created that sought to make using Lisp as easy and powerful as possible. One of these environments is Interlisp, which saw its first release in 1968, and its last official release in 1992. That release was Medley 2.0, which targeted various UNIX machines, DOS 4.0, and the Xerox 1186. Courtesy of the Interlisp open source project (GitHub), Medley Interlisp is available for all to use, even on modern systems.

• InterLisp Fifteen Puzzle by Pixel_Outlaw in his blog
  In some ways, this project was the fulfillment of me wanting to see what Xerox PARC brought to the table during the peak of Lisp AI research. It was from a time when what “Lisp” was was still being explored. You see heavy traces of the era in InterLisp.

• Stringscope, a string listing tool in Interlisp by Paolo Amoroso in his blog
  I wanted to create something small that carries out a limited but useful task. My goal was to familiarize with the Medley Interlisp development environment, tools, and process through developing, optimizing, documenting, and sharing an Interlisp program.

• My encounter with Medley Interlisp by Paolo Amoroso in his blog also cross-posted to Hacker News
  Imagine someone let you into an alien spaceship they landed in your backyard, sat you at the controls, and encouraged you to fly the ship. This is the opportunity Medley Interlisp offers….

• FreeBSD on Dell T3600 by trhawes on Reddit FreeBSD
  … I’m a retro enthusiast who loves Lisp, so natually, I’d want to show off my Medley Interlisp virtual machine (emulating a Xerox Lisp Machine).

• Computers Doing the Right Thing by Amjad Masad in his blog
  Interlisp is one of the most fascinating could-have-been computer systems in history. It shipped with one of the first from-the-ground-up interactive programming environments, structured editor, and many other innovations. Most impressive was the concept of Do What I Mean (DWIM).

• The Interlisp Programming Environment asked by gruseom in Hacker News
  Interlisp was the so-called “west coast” Lisp that emphasized an interactive programming environment and in retrospect looks more like a hybrid between Smalltalk and Lisp than modern Lisp implementations. It was developed at PARC for a while. I don’t know if there was cross-pollination between Interlisp and Smalltalk or if the similarity was a zeitgeist thing.
