In the 1980s Interlisp-D came with a read-only remote desktop client for monitoring networked Lisp workstations, like in the screenshot. Medley Interlisp still includes the code which doesn't currently work.

Screenshot of the black and white desktop of a 1980s graphical workstation environment. The desktop has a gray background pattern and some windows with a white background and a title bar with white text on a black background. The screen shows a scaled down version of the entire remote screen of an Interlisp-D workstation, and a small section at full size which can be moved around.

In Interlisp you could put comments before any expression, but the comment itself was an S-expression – something like (comment here is something interesting about the next expression.) Interlisp was case preserving by default so it worked out alright. But only alright.

Screenshot of the black and white desktop of a 1980s graphical workstation environment. The desktop has a background pattern consisting of a cat head pattern and some windows with a white background and a title bar with white text on a black background. One of the two main windows shows a handmade bitmap drawing of the upper part of a person with the hands on their face. The other window shows the result of layering that bitmap drawing over itself.

The ? command of the Interlisp Exec (REPL) prints a list of available commands with brief explanations of what they do. Most are Interlisp-D commands, some modern Medley additions.

Like other systems developed at Xerox, Interlisp-D supported XCCS (Xerox Character Code Standard), a 16-bit character encoding released in the 1980s. XCCS predated and influenced Unicode. This is version 2.0 of the standard:
