Installation

A disk set is available from http://www.retro11.de/data/oc_w11/oskits/rt11-40_rkset.tgz

Download, unpack and copy the disk images (*.dsk), e.g.

       cd $RETROBASE/tools/oskit/rt11-40_rk
       wget http://www.retro11.de/data/oc_w11/oskits/rt11-40_rkset.tgz
       tar -xzf rt11-40_rkset.tgz

Usage

  • Start disk image in simulator

         pdp11 rt11-40_rk_boot.scmd
    

    or ONLY IF YOU HAVE A VALID LICENSE on w11a

         ti_w11 <opt> @rt11-40_rk_boot.tcl
    

    where <opt> is the proper option set for the board.

  • Hit <ENTER> in the xterm window to connect to simh or backend server. The boot dialog in the console xterm window will look like (required input is in {..}, with {<CR>} denoting a carriage return:

         RT-11SJ  V04.00C 
         
         .D 56=5015
         
         .TYPE V4USER.TXT
         Welcome to RT-11 Version 4. RT-11 V04 provides new hardware support
         and some major enhancements over Version 3B.
         
         Please use the HELP command;  it describes the new options in many
         of the utilities.
         
         If you are using a terminal that requires fill characters,
         modify location 56 with a Deposit command before proceeding with
         system installation. LA36 DECwriter II and VT52 DECscope terminals
         do NOT require such modification.
         
         .D 56=0
         
         .
    

    Now you are at the RT-11 prompt and can exercise the system.

    There is no halt or shutdown command, just terminate the simulator or backend server session.
