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.

In NoteCards a "tabletop card" is an arrangement of cards (hypertext nodes) on the screen, such as the 3 cards at the center.
A "guided tour" is a graph whose nodes are tabletop cards (table icons) and whose edges are links connecting the cards. You traverse a guided tour with the control panel at right and the result is a "slide show" of tabletops.

Since I'm playing with Interlisp-10 on TWENEX I put together a reading list of documentation to get familiar with DEC's operating system.

A NoteCards "browser" is a type of card that shows a hypertext network as a graph structure, i.e. a graph view like in this example. The thumbnail at the top left corner lets you pan and scroll the graph.

ROOMS, developed at Xerox PARC with Interlisp-D, is what we now call a virtual desktop manager. In this 1987 videotape its creators Austin Henderson and Stuart Card present and demostrate the system.

I had my first PR merged into Medley Interlisp.
Although I worked on other PRs related to documentation and the project site, this is the first involving actual system code. The change was absolutely trivial, removing a duplicate line of code, but helped me get familiar with the setup and workflow of tracking and compiling modified files.
It turns out working on system code is pretty much the same as user code. You use the same tools and go through similar steps.
I guess now I'm a hotshot core kernel developer or something.

@interlisp ☝️ The syntax of FORMAT and LOOP blends with Common Lisp in a way similar to how the CLISP notation augments Interlisp. I don't mind the odd syntaxes of these little languages as they don't force to step outside the language for expressing specialized tasks.

CLISP (Conversational LISP) is the Algol-like infix notation of Interlisp. Chapter 23 of the 1978 edition of the Interlisp Reference Manual (page 554 of the PDF) explains the design goals of the notation and how it integrates with the prefix syntax of Lisp.

The 1986 paper "LISP as an Environment for Software Design: Powerful and Perspicuous" presented the features of Lisp for prototyping knowledge-intensive clinical applications, with examples and code in Interlisp.

Using LLMs to chat with books and documents? That's so 1978.
In the 1970s the HELPSYS facility of Interlisp-10 let you interrogate the 700+ pages Interlisp Reference Manual via an English like syntax. You could run queries on topics and system functions such as TELL ME ABOUT EVAL or TELL ME ABOUT THE 2ND ARG OF CHANGEPROP and HELPSYS would print the relevant information or section of the manual. Here's an example session from the 1978 edition of the manual:

Interlisp-10 was the Interlisp implementation for the PDP-10.
Thanks to @SDF I'm checking out Interlisp-10 under the TOPS-20 operating system (aka TWENEX) running on DECSYSTEM-20 hardware. Lots of fun.

To edit a font on Medley Interlisp load and run the EDITFONT font editor like in the screenshot:
(FILESLOAD EDITFONT)
(EDITFONT '(TIMESROMAND 36 BOLD))
Left-click on a character to edit its bitmap, middle-click to bring up a menu.
