Fix for speeding up RSTS/E on my Pi B+

The PiDP-11 manual has instructions for running the software without the front panel. However starting RSTS/E took almost an hour. So I posted the problem on the PiDP-11 google group. Oscar suggested commenting out starting the server startup in /opt/pidp11/bin/pidp11.sh Here is a part of the script with the server commented out

    echo "*** Start client/server ***"
#       sudo ./server11 &
    sleep 2
    sudo ./client11 /run/pidp11/tmpsimhcommand.txt

    # after simh exits, check if a newly created command file now says exit>
    if [[ $(< /run/pidp11/tmpsimhcommand.txt) == "exit" ]]; then
            reboot=1
    else
            reboot=0
    fi

    ((reboot==1))

This. made a huge difference. Before I got a “CPU is too slow” message

After commenting out the server…I still got the “CPU is too slow” message . However it was much closer to the 1M target. And starting RSTS/E went from almost an hour to less than a minute.
