Hello from the Medley Interlisp Project! We revive and modernize the Medley Interlisp extensible graphical operating and programming environment created at Xerox PARC.

https://interlisp.org

We post news & updates, tips, historical info, and more. We look forward to connecting with researchers, software preservation experts, Lisp programmers, retrocomputing enthusiasts, and anyone interested.

The @hist_HT Historic Hypertext Project: Mind-Blowing Hypertext Systems and Paradigms:

"[...] aims at collecting and running historic hypertext systems. We try to install them in virtual machines and provide information about their functionalities and technologies."

The project coordinator is Prof. Claus Atzenbeck @clausatz of Hof University, Germany.

The rise of the Web prematurely ended an era of active research and creative experimentation with hypertext technologies. In this paper @eastgate picks up where this era left off, and presents a neoclassical extension to embed web components in a classical hypertext system.

I'm having too much fun exploring NoteCards, the hypermedia system of Medley Interlisp. It provides a rich hypertext environment and tools as well as an extensive, easy to use Interlisp API.

This is a good introduction:

Since there seems to be renewed interest in #CDE, I thought I'd have a look at the my CDE utilities from back then, which led me to my old Web page “Linux on a VAIO Z600LEK” http://dynalabs.de/mxp.old/vaio/index.html, because there's a screenshot of my work environment from back then. ⇢

I’ve expanded Infinite Mac to cover NeXT operating systems, with the help of the Previous emulator. See https://infinitemac.org/?filter=next for all releases between 1988 and 1997, and https://blog.persistent.info/2024/03/infinite-mac-nextstep.html for tidbits about the porting work and other site updates.

And to keep things in the #MARCHintosh spirit, you can use the Daydream/Darkmatter emulator to run System 7 on the emulated NeXT hardware and so have a replica of one of the more esoteric combos of the early 90s.
