<h3>PDP 11/70 Emulator</h3>
    <p>
      This emulator came about because years ago I was a programmer for RSTS/E on a PDP 11/45 and had admired the console idle loop light pattern - but I couldn't quite remember how it looked. Given the unavailability of real systems it became time to write an emulator!
    </p>
    <p>
      I was going to start with a PDP 11/45 emulator but the extra memory of a PDP 11/70 became far too attractive (nearly a whole 4MB!). I eventually wrote a
      <a href="pdp11.html">PDP 11/70</a> version as well as a
      <a href="pdp11-45.html">PDP 11/45</a> version, and later also a
      <a href='../pdp10/pdp10.html'>PDP-10</a>.
    </p>
    <p>
      I met my core objective - I can now see the RSTS/E console light pattern that I was looking for, and found that newer versions (eg v9.6) have a different light pattern. Also I have now seen some of the light patterns for other OSes. RSX and BSD 2.11
      have their own different patterns, and Unix V5 and Ultrix operate with absolute minimum light movement (I'm assuming they operate mostly in WAIT mode).
    </p>
    <p>
      Getting all of the operating systems used here presents its own set of challenges - one of which is finding the software in the first place. But one of the most interesting was RSTS/E V06C which has its own
      <a href='RSTSv06c.html'>story</a>.
    </p>
    <p>
      Many of the systems also include source in some form or another and it is very interesting to see the different approaches they used. All had a profound influence on systems which evolved later and unix in particular would be familiar to administrators of current systems. I reflect that if I had been exposed to Ultrix earlier I might have chosen a different career path.
    <p>
      The boot code in this emulator is a custom PDP 11 program running with it's own set of light patterns. It is initially loaded at address 120000 and includes a LIGHTS command which operates by mapping and executing a WAIT instruction from a pattern of virtual addresses. The resulting display simply shows the content of R0 and the address of the instruction being executed. You can also use the BOOT command to start one of the guest operating systems listed below, or the ODT command to start a version of the Octal Debugging Tool.
    </p>
    <p>
      However boot code like this was not part of early PDP 11s. These systems had no BIOS or other software to help get the bare metal started. If you were lucky perhaps the previous boot code would still be intact in non-volatile magnetic core memory, but in general booting the system required toggling in a small bootstrap loader from the front panel.
    </p>
    <p>
      Here is an example of the switch commands for booting from an RK05 where the value at address 1002 selects the unit number (rk0, rk1, rk2, etc). Goodluck!
    </p>

      If you wish to toggle in a simple light chaser to the front panel then here are some switch commands which can be used:

   Dungeon is a game of adventure, danger, and low cunning.  In it
you will explore some of the most amazing territory ever seen by mortal
man.  Hardened adventurers have run screaming from the terrors contained
within.

   In Dungeon, the intrepid explorer delves into the forgotten secrets
of a lost labyrinth deep in the bowels of the earth, searching for
vast treasures long hidden from prying eyes, treasures guarded by
fearsome monsters and diabolical traps!

   No DECsystem should be without one!

   Dungeon was created at the Programming Technology Division of the MIT
Laboratory for Computer Science by Tim Anderson, Marc Blank, Bruce
Daniels, and Dave Lebling.  It was inspired by the Adventure game of
Crowther and Woods, and the Dungeons and Dragons game of Gygax
and Arneson.  The original version was written in MDL (alias MUDDLE).
The current version was translated from MDL into FORTRAN IV by
a somewhat paranoid DEC engineer who prefers to remain anonymous.

&gt;<b>HELP</b>
Help is available for many RSX-11M commands and utilities.
For help in logging into the system, type HELP HELLO or HELP
LOGIN.  You'll need a user-ID and password to log in.  Ask your
system manager.
RSX-11M systems have two major command languages or CLIs:  MCR
and DCL.  Once you log in, your terminal is set to either
MCR or DCL.  (All terminals are set to MCR prior to logging in.)
The general forms of the HELP command are:
&gt;HELP[/cli] topic [subtopic[s]]
&gt;HELP commandname [switch]
Once you are logged in, you need not include the name of the CLI
to which your terminal is set.
For information on what further help is available, type
HELP[/MCR] LIST (brackets indicate an optional command line
entry) or HELP/DCL.  For a listing of help available on other
topics, type HELP[/MCR] MORE or HELP/DCL MORE.  You need not
log in to get help.
