Codeberg deployed Forgejo v13.0.0 which now detects Interlisp sources and handles them as text rather than binary files. We thank Forgejo and Codeberg for widening the choice of code forges for hosting Interlisp software.

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.

Published in 1986, "INTERLISP: The Language and Its Usage" by Stephen Kaisler was the only book on Interlisp by a publisher. It extensively covers the Interlisp language and environment with many code snippets and examples.

We added "NoteCards User’s Guide" V2.0 to the NoteCards sources. This 1991 manual better matches the NoteCards code that comes with Medley Interlisp but some of the information is only of historical value.

Some 1980s Xerox Lisp Machines came with an IBM PC/XT card that allowed running MS-DOS from the Interlisp-D environment, like the spreadsheet program window here. Image from a flyer of the Xerox 1186 AI workstation.

To interactively edit a graph on Medley evaluate at an Interlisp 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.

In NoteCards a "tabletop card" is an arrangement of cards (hypertext nodes) on the screen, such as the 3 cards at the center.

In Interlisp the variable IT holds the value of the most recent event or expression evaluated at an Exec (REPL) and is similar to the variable * of Common Lisp. An example:

← (PLUS 5 3)
8
← (PLUS IT 2)
10

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.

Although NoteCards predated the WWW, in the early days of the web the Xerox PARC hypermedia system was also used for research on the design, analysis, and documentation of web sites such as the projects described in these papers.

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.

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