/23+, no?=C2=A0 The basic 23 doesn't have = an MMU, I'm pretty sure.

I remember on MiniUnix (a stripped down kernel that woul= d run on PDP11=E2=80=99s
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.
