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" Absolutely. When I was an impoverished grad student at Berkeley, Zilog hired me as a consultant to port vi and the other Berkeley tools to their Z8000 UNIX system. It was a treasured paying gig. As I recall, it was a 16 bit system (with some addressing enhancements ala the 11/70). By then, the VAX was popular and everybody wanted 32 bit systems. People were pinning their micro-UNIX hopes on the Motorola 68K. Even before Zilog's ZEUS, Onyx came out with a microwave oven-sized box based on the Z8000. They loaned one to Berkeley, and it was my first home computer when I took it home to port the tools. Everything had to be copied over by serial port.     Mary Ann On 1/21/20 9:52 AM, Jon Forrest wrote: > There's been a lot of discussion about early Unix on Intel, National > Semi, Motorola, and Sparc processors.
