X-BeenThere: tuhs@minnie.tuhs.org X-Mailman-Version: 2.1.26 Precedence: list List-Id: The Unix Heritage Society mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: tuhs-bounces@minnie.tuhs.org Sender: "TUHS" There's been a lot of discussion about early Unix on Intel, National Semi, Motorola, and Sparc processors. I don't recall if Unix ran on the Z8000, and if not, why not. As I remember the Z8000 was going to be the great white hope that would continue Zilog's success with the Z80 into modern times. But, it obviously didn't happen. Why? Jon
