The Medley Interlisp ProjectIn 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.

Paolo AmorosoOn 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.
Interlisp has something "ugly" and "horrible": data for which READ is not an inverse of PRINT (ugly), or that cannot normally be dumped and loaded easily (horrible) such as structures containing user datatypes, arrays, hash tables, or list structures.

The FAQ of Medley Interlisp answers some basic questions on using the system such as whether clipboard support is available, how to get online help, large displays, and more.
FAQs
Is copy and paste available? In Medley, there are three main editors used commonly: TEdit (full WYSIWYG styled text editor) SEdit (structure editor for Lisp code, package aware) TTYIN (Type-in using keyboard) The original method for copy/paste is different from most modern systems: click with mouse the destination hold down the shift key, and, while holding, select the source (using left mouse button to select a point, right button or repeated left button to extend the selection) let up the shift key. The system will copy from the selected content and paste it in the destination. To do a cut/paste operation, hold down the control key as well as the shift key.
This 1984 paper introduced the basic ideas of programming with objects in various languages with examples from LOOPS, the Lisp Object-Oriented Programming System of Interlisp.

I fixed an Insphex issue I introduced by accessing internal system details that later changed. Insphex is my hex dump tool for Medley Interlisp.
