Subject: [pups] PDP-9?
Date: Mon, 2 Sep 2002 09:13:13 +0200	[thread overview]
Message-ID: <7AD18F04B62B7440BE22E190A3F772146845@mwsrv04.microwalt.nl> (raw)

Unix was _developed_ on the 11/20.  The first versions (up to  the
fourth or fifth edition or so) didn't require an MMU, and, therfore,
had no protection whatsoever.

Dennis... tell us the "All out?" story.. please.. :)
