I'm looking for source code written in the Simula I programming language (not just snippets, but ideally real projects that are known to work). Note that I'm talking about the Simula version which appeared in 1962, not the one from 1967, which was the first OO language (see e.g. https://web.archive.org/web/20160318165616/http://www.edelweb.fr/Simula/#7).

I'm aware that there is a small chance that Simula I code still exists and is accessible, but I just try my luck.
