w11: PDP-11/70 CPU and SoC
The project contains the VHDL code for a complete DEC PDP-11 system: a PDP-11/70 CPU with memory management unit, but without floating point unit, a complete set of mass storage peripherals (RK11/RK05, RL11/RL02, RK70/RP06, TM11/TU10) and a basic set of UNIBUS peripherals (DL11, LP11, PC11), and last but not least a cache and memory controllers for SRAM and PSRAM.Mon May 14 11:31:23 2018 - permalink -
The design is FPGA proven, runs currently on Digilent Cmod A7 , Arty , Basys3 , Nexys4 DDR , Nexys4 , Nexys3 , Nexys2 and S3board boards. See section Complete Systems for more information.
5th Edition UNIX, 7th Edition UNIX, and 2.11BSD UNIX are known to boot, the hardware should also support DEC RT11 and RSX-11M, see section Running Systems for more information.
This is a retrocomputing project, rebuilding hardware from the late 70s and running historical software. To get into the tune see Figure D-1, a 11/70 console, and Figure F-2, a baseline system setup.- https://wfjm.github.io/home/w11/

Computer History Wiki
This wiki is an experiment to create a means for knowledgeable people to enter their information into some kind of a knowledge base. This is however, not the relatively formalized tone and style imposed by Wikipedia. Sentences starting with "I seem to recall" are perfectly welcome here - and articles do not have to be in the descriptive, encyclopedic style Wikipedia enforces. On the contrary, it is preferred that many of the articles be references, guides, helpful hints, suggestions, tutorials and so on.Fri Nov 17 13:44:15 2017 - permalink -
If you have any information you want to contribute to this wiki, please, contribute it. We'd much rather remove or modify a dozen potentially unsuited submissions than miss out on a single good one. We hope this wiki grows into a useful resource for everyone interested in classic computing, no matter what their level of knowledge may be; it is meant to be all-encompassing. -- Tore & Lucky- http://gunkies.org/wiki/Main_Page#News
