A new favorite project: People from 1970s PARC + PARC-adjacent folks are carefully restoring/gently modernizing the Medley Interlisp system, a Lisp OS that ran on the Xerox D-machines, so that it can run on a modern VM on any OS.

#lisp pretty cool to run #Interlisp Medley in a browser. Supports also Common Lisp. Thanks to @masinterand team! Check out the original image-based software development, dating back to BBN Lisp of the 60s, renamed Interlisp later!

It was SUCH a productive working environment, so much better than any IDE we have today. It had two problems: it was expensive, and it was slow. But an 1108 ran at about a million instructions per second; my current Ryzen 5 runs at 86 billion. So speed isn’t so much of a problem!

Retro projects are often extremely toxic, but here they’re taking care to set up a modern dev community (Zoom calls, code of conduct), enhancing docs, publishing a thorough annual report, and preserving “legacy” versions of the software too.

. @interlisp8 informs me that you - yes, you! - can still experience the Interlisp experience from the ’80s. https://t.co/JK1OgEaCMN

Interlisp came from the same milieu as Smalltalk and (I’m told) had a similar experience. People interested in recovering lost lessons, take note.

Back in the 1980s when we used actual modern computers, @DefnPodcast, the way Interlisp handled multiple concurrent breaks in multiple threads was to pop up multiple break inspector windows on the screen, which you could deal with in whatever order.https://t.co/AxTGFc7W8Q

Interlisp was a fascinating language that influenced the definition of Common Lisp. However, a couple of prime features have not found much traction: DWIM and structure editing. This manual hints at a lost future that’s both inspiring and depressing all at once. pic.twitter.com/NPKIBklsjk
