Message-ID: <em0f613556-341a-4fac-8285-8b4886203690@8db92fc1.com> (raw)

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.
