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" I read in the PDP-7 reference manual that Precision CRT Display Type 30 and Precision Incremental Display Type 340 are the typical displays used with the PDP-7, but aren't standard equipment. I read about the Graphics-II scope. Was it the only display? I read it was used as a second terminal and that it would pause per display full with a button to continue. I assume this second terminal's keyboard was TTY model 33 or similar since it was the standard equipment. Does anyone know? Do you know if the PDP-7 or early edition Unixes have pen support for that Graphics-II or similar displays? Clem has written that the PDP-7 had a disk from a PDP-9. Where is this cited? The ~1971 draft "The UNIX Time-Sharing System" says first version runs on PDP-9 also. https://www.tuhs.org/Archive/Distributions/Research/McIlroy_v0/ But I cannot find any other reference of running on PDP-9 at all. Was this academic? That draft calls the PDP-7 version the "first edition" but later the PDP-11/20 is called the "first edition". When did the naming of first edition get defined to not include the PDP-7 version? Or is it because the early "0th" version was never released/shared outside? Thompson interview https://www.tuhs.org/Archive/Documentation/OralHistory/transcripts/thompson.htm mentions an "interim machine" and a "PDP-11 that had PDP-10 memory management, KS-1." What is this interim machine? Is this a PDP-11 without a disk (for a few months?) What is this PDP-11 and KS-1? Maybe this is the PDP-11/20 with KS-11? Do we know what hardware was supported for the early editions? We don't have all the kernel code and from a quick look from what is available I didn't see specific hardware references. The later ~1974 "The UNIX Time-Sharing System" paper does mention some hardware at that time on the PDP-11/45 like a 201 dataset interface and a Tektronix 611 storage-tube display on a satellite PDP-11/20. When did a CRT with keyboard terminal like DEC vt01 (with Tektronix 611 CRT display), LS ADM-3, Hazeltine 2000, VT01A display with keyboard (what keyboard?) get supported? Any code to help find this? (The https://www.bell-labs.com/usr/dmr/www/picture.html does mention the VT01A plys keyboard). Thanks, Jeremy C.
