On Medley Interlisp, if you highlight a menu item without releasing the mouse button an explanation of what the item does, if available, will be printed in the Prompt Window (the black one). This is conceptually similar to tooltips on modern systems. https://interlisp.org/documentation/Medley-Primer.pdf#page=23 #interlisp #lisp

RE: https://fosstodon.org/@interlisp/117058797209764802 Interlisp-D running on Xerox workstations also had TeleRaid, a remote debugger that worked over an Ethernet PUP network connection. https://files.interlisp.org/medley/library/TELERAID.TEDIT.pdf #interlisp #lisp #debugger

URAID is the low level debugger and diagnostic tool of Medley Interlisp. The name comes from "Unix RAID", the latter likely a pun on the insecticide of the same name. This 1991 manual of Medley for Sun describes the URAID commands. https://interlisp.org/documentation/SunUserGuide.pdf#page=61 #interlisp #debugger #retrocomputing
