Mueller" <w.f.j.mueller at gsi.de> Org: Technische Universitaet Darmstadt 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.
