I remember on MiniUnix (a stripped down kernel that would run on PDP11’s
without memory management, in our case 11/03, 11/20, and an older 11/40)
there were no kernel pipes (and limited process concurrency).
The shell used the aforementioned emulation of pipe by just running the
output of one process into a temporary file subsequently loaded as stdin
of the other.
We kind of put all that to bed when the 11/23s came out and we could run
our full up kernel on the micros.
