<br />
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.<br />
<br />
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.<br />

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.<br>(<a href="https://roland.iwasno.net/links/?iDeK7g">Permalink</a>)PDP2011 Overview « PDP2011https://roland.iwasno.net/links/?h8B65g2014-08-12T14:29:33+02:00This website describes PDP2011 – a re-creation of the well known series of PDP-11 computer systems in VHDL. Everything that is needed to run a complete PDP-11 system is included; you can run a complete Unibus PDP-11 system with console, disks and other peripherals on a simple low cost FPGA development board.
