[TUHS] Unix without pipes

If I'm remembering correctly, miniunix didn't have pipes. The shell faked
it by taking the output of the first program into a file and then using it
as the input for the second.
Didn't really multitask anyhow, so it was pretty much fine.

Is this a SCO speciality, or are there other UNIXes like that?
Does it not even have pipe() in its libc?
