RetroChallenge announced the results of RC2024/10 and I'm honored to be among the winners. I entered with the WebCard project written in Interlisp, a NoteCards extension for visiting websites.

Thanks to the organizers, voters, and judges and congrats to all the entrants, especially @psychotimmy who won the Grand Prize.

To scroll a window on Medley Interlisp hover the mouse pointer slightly beyond the left or bottom edge to bring up a scroll bar, then left-click or right-click. Middle-clicking positions the thumb within the bar.

The Interlisp documentation has a distinctive style that conforms to "Xerox Publishing Standards: A Manual of Style and Design" published in 1988 in this edition. It was the Xerox house style, i.e. the style guide for company publications and documents. The manual covered everything from the publishing process to visual design.

In the 1980s some Xerox Lisp Machines came with an IBM PC/XT expansion card that allowed running MS-DOS software from the Interlisp-D environment, like the black window of a spreadsheet program at the bottom left. This screenshot is from a flyer of the Xerox 1186 AI workstation.

To interactively edit a graph on Medley evaluate at an Interlisp Exec (a REPL):

(SHOWGRAPH NIL NIL NIL NIL NIL T)

Right-click inside the window for a command menu, click STOP to exit. Right-click on the title bar and click Shape to resize the window.

Medley Interlisp is a living fossil more than the mataphor implies.

The build process doesn't compile the Lisp sources but mostly combines existing compiled files generated up to a few decades ago. Almost a third of the Medley sources haven't been compiled since Jan 25, 1998, and many of the sources dated from years before. It's as if your current Linux distro was built from .o files compiled 27 years ago.

How's that for maturity and stability?

Medley Interlisp is like the universe of a fantasy novel: weird but logical and self consistent.

This paper reported on the 1980 Lisp conference, the second ever after the one in 1964. It's a time capsule of the state of Lisp and its dialects at the time, including Interlisp, in which G.L. Steele provided the abstracts of the papers presented at the event and added his own commentary.

And now for something completely meta: Interlisp-10 inside Medley Interlisp.

The terminal emulator of the window at center is connected to SDF's PDP-10 system running Interlisp-10 under TOPS-20 (TWENEX). The shell with the terminal emulator and Medley Interlisp are running on Linux.

With @interlisp Medley Interlisp I'm BBSing like it's 1985. The center window is a terminal emulator with a Telnet session connected to the RC-BOX BBS by @Wintermute_BBS running on a @rc2014 Z80 system. The shell with Telnet as well as Medley Interlisp run on Linux.
