Paolo AmorosoThe document preparation system of Symbolics Lisp Machines consisted of two main hypertext tools, the Concordia authoring environment and the Document Examiner documentation browser and delivery interface.

Alfred M. SzmidtYou know how and can do it with a chisel, but what you're presented with is a monster CNC machine to just make a simple square. (It is why I like "retro" computing, <a href="https://mastodon.social/tags/LispMachine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LispMachine</a> <a href="https://mastodon.social/tags/LispM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LispM</a> -- I can hack without having to spend several months on just using tools to do shit I know how to do).

Emacs is an editor, nothing more or less. It is not a Lisp environment, or a Lisp implementation. And yes, it is about Lisp, an extensible language. Emacs is special, but it is for other reasons. <a href="https://mastodon.social/tags/GNU" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GNU</a> <a href="https://mastodon.social/tags/Emacs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Emacs</a> is a far shot from <a href="https://mastodon.social/tags/LispM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LispM</a> <a href="https://mastodon.social/tags/LispMachine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LispMachine</a>, and ZWEI is a far shot from <a href="https://mastodon.social/tags/GNU" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GNU</a> <a href="https://mastodon.social/tags/Emacs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Emacs</a>.

Paolo Amoroso<a href="https://mastodon.ie/@surabax" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@surabax</a> 👆 What I find interesting in this Symbolics Genera retrospective by David Moon is the discussion of the origins and motivations behind the lack of kernel protection in the Lisp Machine environment and, more generally, in Lisp. These features emerged from social dynamics and values like the opennes of hacker culture as much as from engineering design decisions.<a href="https://fosstodon.org/tags/lisp" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#lisp</a> <a href="https://fosstodon.org/tags/symbolics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#symbolics</a> <a href="https://fosstodon.org/tags/LispMachine" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LispMachine</a>

Ramin Honary<a href="https://www.burgerrg.com/TR413.pdf%20" rel="nofollow noopener noreferrer" target="_blank">1994 Indiana U., Robert G. Berger: “The Scheme Machine”</a><blockquote>This paper describes the design and implementation of the Scheme Machine, a symbolic computer derived from an abstract Scheme interpreter. The derivation is performed in several transformation passes. First, the interpreter is factored into a compiler and an abstract CPU. Next, the CPU specification is refined so that it can be used with the Digital Design Derivation system. Finally, the DDD system assists in the transformation into hardware. The resulting CPU, implemented in field programmable gate arrays and PALs, is interfaced to a garbage-collecting heap to form a complete Scheme system.</blockquote><a class="hashtag" href="https://fe.disroot.org/tag/scheme" rel="nofollow noopener noreferrer" target="_blank">#Scheme</a> <a class="hashtag" href="https://fe.disroot.org/tag/schemelang" rel="nofollow noopener noreferrer" target="_blank">#SchemeLang</a> <a class="hashtag" href="https://fe.disroot.org/tag/lispm" rel="nofollow noopener noreferrer" target="_blank">#LispM</a> <a class="hashtag" href="https://fe.disroot.org/tag/lispmachine" rel="nofollow noopener noreferrer" target="_blank">#LispMachine</a>
