It's maintained now entirely within MIT/Scheme but Im discovering other ancient scheme dialects were using it as their default editor, which implies to me it had a life of it's own at one point.
Having trouble finding any HISTORY files or anything.
@cwebber @catonano So what piqued my curiosity is that Texas Instruments appears to have been using Edwin directly integrated into PC-Scheme in the 80s. PC-Scheme was eventually released under a clumsy pseudo libre license; but it doesn't seem like it could possibly square with any terms GNU Emacs would have been distributed under.
I don't pretend to know when Edwin started shipping with MIT/Scheme but that seems wierd that they would both be aware of each other and both include emacs-like scheme based REPL integrated editors under the same name.
Just feels like there is a story there, though maybe a tiny one.
