The QNX demo, from 25Y ago? Oh, yes. The miracle is that it worked at all, not that it's very complete.

The full OS was a ~100MB download:

The full OS was 1.4 MB, but they've distributed some additional software as well.

    Well, no, not really, AFAIK.

    But it depends what you define as "the full OS".

    It is mainly an embedded OS for routers and engine-control units and traffic lights. For that role, it doesn't need a GUI or a desktop or dev tools or a network stack.

    So are they part of the "full OS"?

    It depends where you stand, and how you look at it.

    The Demo Disk contains a lot more than 1.4MB of code. It's more like 3-4MB of code, but that does not mean it is "the full OS".
