Building the Interlisp system
Medley Interlisp is open-source and may be obtained from GitHub. It is portable to many different Linux and Apple MacOS systems, as well as Windows using WSL2.
The core is written in portable C. The system currently depends on an X11 system for its display.
Obtaining The System
The system comes in two parts. The first is a C-based virtual machine Maiko.
The remainder of the system is OS / architecture-independent and can be found in the Medley repository.
You can now download Medley Interlisp from a release without building anything; see the Medley README
See The Maiko README for build instructions for Maiko, for systems for which there is no pre-built release.
(See Medley repo README for instructions on getting Medley. Make sure you have an X-server running to manage the Medley Interlisp display, and the DISPLAY environment variable set to point to your X-server.
Running Medley can be done by typing:
$ cd medley $ ./run-medley
Or, if you wish to start Medley up with a particular image file (SYSOUT):
$ cd medley $ ./run-medley <SYSOUT-file-name>
The first time the system is run it loads the system image that comes
with the system. When you exit the system (or “do a
SaveVM” menu option)
the state of your machine is saved
in a file named
~/lisp.virtualmem. Subsequent system startups
~/lisp.virtualmem image by default.
Exiting The System
The system may be exited from an Interlisp prompt by typing:
Or from a Common Lisp prompt with:
When you logout of the system, Medley automatically creates a binary dump of your system located in your home directory named ``lisp.virtualmem’’. The next time you run the system, if you don’t specify a specific image to run, Medley restores that image so that you can continue right where you left off.
