@hosford42 I also have no idea about any associated IP or patents, though. Wouldn't whoever does it need to be able to prove they never saw the original code, just its outputs? Otherwise you're still infringing, aren't you? In this regard, it's probably actually a bad thing that the dectalk sourcecode is so widely available.

And most of the commits seem to be about just getting it to compile on modern systems with modern toolchains. I dread to think how unsafe closed-source C code written in 1998 is.
