The first video is the same as https://softwarepreservation.computerhistory.org/FP/#Backus1... .

I hadn't seen the Group Meeting video; I will add it (even though it's very rough).

I will change the entry for [Booch2007] to include the video as well as the transcript.

In that first diagram (https://softwarepreservation.computerhistory.org/FP/Composin...), A and B are supposed to be pure functional programs; side-effects are modeled by each one outputting a new version of each modified input. In the second diagram (https://softwarepreservation.computerhistory.org/FP/Strict_H...), as actually implemented in FL, they stick to strictly leftmost-innermost evaluation order so that side-effects are at consistent (but this presumably prevents parallel evaluation).
Can we move this conversation to email? I am not sure what diagrams you are referring to.
Thanks very much; I in turn will add a link the Related Resources section. If you'd like to be recognized as other than metazip then let me know via email.
Author here. This is work-in-progress, not linked from top level. I'll keep working.

I donated https://www.analogmuseum.org/library/beckman_EASE_installati... to this web site. The original was from my father-in-law, Professor Cyril P. Atkinson at U.C. Berkeley.

Sigh -- they keep changing the rules. I think you have to have a free ACM account. If you send me an email (see my home page in my profile), I'll send you a PDF.

The link dump includes scans of the source code and a link to this free-to-read paper on the history of the Lisp 2 project: https://ieeexplore.ieee.org/document/8267589 (I’m the author).

And here's an English translation of the History chapter from Stoyan's 1980 book _LISP-Anwendungsgebiete, Grundbegriffe, Geschichte_ [LISP Application, Basic Concepts, History]: https://softwarepreservation.computerhistory.org/LISP/book/S...

Here are some bibliographies, including an extensive (but old) one by Herbert Stoyan. Apologies for the rough formatting of them: https://softwarepreservation.computerhistory.org/LISP/resour...

And it's worth pointing out here that the book itself is now freely available: https://dl.acm.org/doi/book/10.5555/542865

Was your work on the 6502 perhaps in the 70s?

One of my younger brothers died a few weeks ago (he was 67; I'm 75). When people offer sympathy, I accept it and don't question their motives or involvement.
An X-ray machine was in the shoe store when I was little, but my father told us not to let it be used on us.
