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.

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.

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.
