I think so, though it wasn't high on the list of features. Nor should it be. But the message system in particular (for communicating between kernel processes) makes for a very interesting design. Adding networking was as simple as extending the message system beyond the local cluster, and Tandem was running an internal world-wide network by the early 1980s. It makes an interesting (if not particularly good) comparison with the Internet. Greg -- Sent from my desktop computer. Finger grog at FreeBSD.org for PGP public key.
