UNIX System V Release 2.0 runs on PDP-11/70s having fairly standard
peripheral configurations.  There are a few restrictions (no flexnames,
for example) and newer features such as "shl" (shell layers) are not
supported on the PDP-11/70.

One does wonder why the AT&T sales force has such difficulty answering
routine questions like this.
