Apple might sue you though, like they did DRI :-)

Just discovered the videos ( https://www.youtube.com/@NostalgiaPCTV ) ...and the source code on github reads like a book. Amazing.

This rewrites what-could-have-been history a bit... better get my IBM XT/286 out of storage! Is this for real?

From Computerphile - nice insight in the guts of Lisp from the IBM 704 and PDP-6 Lisp. Software archaeology can be insightful :-)

This famous 'hacker OS' was the birthplace of rather a lot - emacs, AI living in a 3D world, as well as the Open Source culture. A reconstruction project has brought it back to life. It's fun to experience what it was like ci

A practical tip that works miracles on 5.25 diskettes: rub their edges against a table top or whatever, making them sit looser in their sleeves. Does miracles to disks that cause read errors - strange as it sounds. Also, using an 80 track d

Wow! How did I manage to miss this treasure trove! Thank you.

But we'd need to backport emacs to the PDP-1 then :-)

I was wrong - it was not Peter Deutsch who ported Eliza to Lisp, it was Bernie Cossell at BBN (one of the famous IMP Guys a few years later!). And it is here: https://github.com/jeffshrager/elizagen.org/tree/m

Actually, https://github.com/cl-aip/eliza/ would be a great starting point for a backport to Lisp 1.5. Hmmm...

by ozymandiax 3mo ago
We already have it running on the PDP-10 reconstruction, and it is known that people around Deutsch at BBN ported it back to the PDP-1. But that version has been lost. From the link you gave, a backport would be feasible... especially becau

I was born too late (not a bad thing necessarily) to have experienced that founding era. But I think that for later generations, there's a lot to learn still from what evolved in the earliest years. We've gained a lot since then,

When we visited some of the 1970s 'heros' of the MIT AI Lab, we were told the informal story behind SHRDLU, the AI living in a PDP-10 3D world. How this graphical AI triggered the first AI Summer -- https://www.youtube.

The PDP-1 Lisp page has 4 rather good books linked as PDFs. Oh - but all on the earliest history of Lisp as well! That is not what you're looking for I think.

Written by Peter Deutsch, then a then-high school student on a tiny 4K (admittedly, 4K 18-bit words) machine. Amazingly usable - and lives on in the Python REPL concept. Our PiDP-1 simulator on github lets you try it out on any Linux machin

Simulator is on https://github.com/obsolescence/pidp1 . It does not need a hardware front panel, runs with an on-screen virtual one too.

And pretty authentic development tools as well - I hear Michael Gardi used Macro1_1, which though a cross assembler, is pretty much the Macro on the PDP-1 itself.

My favourite computer... timing instruction placement on the drum. Juergen is actually planning to make a batch of kits later this year!

Yes, with the PiDP-10 we did a huge injection mold and it nearly killed us. Well, no, but we still have not recovered the investment. And it became an expensive thing, which limits the amount of people who want to play with one. So with the
