Paolo AmorosoThis 1983 paper reported on the experience with implementing the same applications on three different Lisp systems: Maclisp on a DEC-20, Franz Lisp on a VAX 11/780, and Interlisp-D on a Dolphin workstation. Despite the graphical environment the poor performance of the Dolphin hardware, one of the slowest Xerox D machines, made the Interlisp-D experience worse than other systems.
@amoroso It's a real shame Xerox didn't #OpenSource #InterLisp in the 1980s. Ported to cheap commodity hardware -- Acorn ARMs, Sun SPARCs, DEC Alpha or whatever -- it could have changed the history of computing, and vastly for the better.
The Medley Interlisp ProjectModern Medley Interlisp can read and write files where 16 bit character codes are represented as UTF-8 byte sequences or UTF-16 byte-pairs, and convert from and to Unicode codes to equivalent internal Medley codes. For details see:

SAILDART "is an archive of the first Stanford Artificial Intelligence Laboratory derived from its final backup tapes". Lots of historical material since the 1970s, see for example the files of Don Knuth (DEK), John McCarthy (JMC), and Larry Masinter (LMM).
This 1986 paper reported on various extensions and forms of collaboration for the NoteCards hypertext-based idea structuring system. Written in Interlisp, NoteCards was essentially a single user hypermedia environment at first.

In the late 1970s Interlisp was ported to DEC VAX computers under Berkeley Unix. These papers reported on the project and its challenges.

To try out the bitmap editor of Medley Interlisp evaluate (EDITBM (CURSOSRBITMAP)) which edits the bitmap of the mouse pointer. Middle-click on the gray area at the top and select Abort to exit with no changes, otherwise select OK.
To learn how to use the tool see:
Originally written in the 1980s for the Interlisp-D environment and later Medley, LFG Grammar Writer's Workbench is a graphical platform for linguistic research within the Lexical Functional Grammars theoretical framework. This manual of the application was published in 1996.

On Medley Interlisp "image objects" are data objects embeddable in windows or documents, a facility similar to Microsoft OLE.
This is all the code I wrote to implement a basic image object that holds a single line of text. An actual such object is embedded in the window of the TEdit WYSIWYG editor. To insert the object I evaluated `(MAKE.TXTOBJ "I am an image object")` in TEdit.
