As part of my ongoing history project, I am checking hardcopy documents I have against online archives to try to notice when things I'm forced by circumstance to get rid of are available from some other source. I noticed web pointers to something called the Lagout Museum [1], which was a web site that had a lot of old computer documents, but in particular some Symbolics lisp machine documents. It's gone now, so I was getting 404s. But I found it on the Internet Archive's amazing Wayback Machine [2]. Sadly, it's a pain to browse because the historical artifacts [3] contain code that pops up a prompt for donations. So, always up to a challenge, I used my netsettlement git(hub) repo to host a browsable mirror of the directory structure (not the actual files) that does not have the pop-up menu problem. It's better explained in the README.md at https://github.com/netsettler/netsettlement/blob/main/symbolics/lagout_museum/ for more details.
