Subject: VHDL implemenentation of a PDP-11/70 available on OpenCores
Id: <i2kmn9$vhj$1 at lnx107.hrz.tu-darmstadt.de>
========
A VHDL implementation of a PDP-11/70 with MMU but without FPP,
and a basic set of UNIBUS peripherals is available under GPL
on OpenCores, see
http://opencores.org/project,w11
The core is FPGA proven, boots UNIX 5th edition and 2.11BSD Unix.
The I/O sub-system is emulated via a backend server which currently
communicates via a serial port with the FPGA board.
