+As I mentioned in the "[PDP-11 Tutorials](http://www.pcjs.org/blog/2017/01/03/)" blog post, I've been working on
+some methods for visually illustrating how machine components work.  And the PDP-11/70 Operator's Console,
+with its many blinking lights and switches, seemed like a good candidate.
+
+NOTE: I prefer the generic term "Front Panel" to describe DEC's Operator's Console, because it's less ambiguous and
+more generally recognized and understood.
+
+I still haven't written a *real* tutorial on the PDP-11/70 Front Panel, which will require starting at a much more
+fundamental level, explaining and demonstrating each switch in turn.
+
+However, I have made more progress on the basic elements that any tutorial or demo requires: allowing the user to walk
+through a step-by-step demonstration of some procedure.
+
+To illustrate, I've copied a multi-step procedure from the page on [Toggle-Ins](/devices/pdp11/machine/1170/panel/debugger/#toggle-ins)
+that shows how to use the PDP-11/70 Front Panel to verify that the Memory Management Unit (MMU) is operating properly.
+
+The procedure involves entering a small 3-instruction program at address 200 that will write a value (070707) to
+address 200, executing the program, and then verifying that the MMU relocated that value to address 300 instead.

+{% include machine.html id="test1170" %}
+
+Step 1: Load ADDRESS register with 200.
+
+{% include machine-command.html type='clickOnce' label='LOAD 200' machine='test1170' command='script' value='set Panel SR 200; sleep 500; hold Panel LOAD 250' %}
+
+Step 2: Deposit 012737 at ADDRESS 200.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 012737' machine='test1170' command='script' value='set Panel SR 012737; sleep 500; hold Panel DEP 250' %}
+
+Step 3: Deposit 000400 at ADDRESS 202.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 000400' machine='test1170' command='script' value='set Panel SR 000400; sleep 500; hold Panel DEP 250' %}
+
+Step 4: Deposit 177572 at ADDRESS 204.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 177572' machine='test1170' command='script' value='set Panel SR 177572; sleep 500; hold Panel DEP 250' %}
+
+Step 5: Deposit 012737 at ADDRESS 206.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 012737' machine='test1170' command='script' value='set Panel SR 012737; sleep 500; hold Panel DEP 250' %}
+
+Step 6: Deposit 070707 at ADDRESS 210.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 070707' machine='test1170' command='script' value='set Panel SR 070707; sleep 500; hold Panel DEP 250' %}
+
+Step 7: Deposit 000200 at ADDRESS 212.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 000200' machine='test1170' command='script' value='set Panel SR 000200; sleep 500; hold Panel DEP 250' %}
+
+Step 8: Deposit 000000 at ADDRESS 214.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 000000' machine='test1170' command='script' value='set Panel SR 000000; sleep 500; hold Panel DEP 250' %}
+
+Step 9: Load ADDRESS register with 300.
+
+{% include machine-command.html type='clickOnce' label='LOAD 300' machine='test1170' command='script' value='set Panel SR 300; sleep 500; hold Panel LOAD 250' %}
+
+Step 10: Deposit 300 at ADDRESS 300.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 300' machine='test1170' command='script' value='hold Panel DEP 250' %}
+
+Step 11: Load ADDRESS register with 17772300.
+
+{% include machine-command.html type='clickOnce' label='LOAD 17772300' machine='test1170' command='script' value='set Panel SR 17772300; sleep 500; hold Panel LOAD 250' %}
+
+Step 12: Deposit 077406 at ADDRESS 17772300.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 077406' machine='test1170' command='script' value='set Panel SR 077406; sleep 500; hold Panel DEP 250' %}
+
+Step 13: Load ADDRESS register with 17772340.
+
+{% include machine-command.html type='clickOnce' label='LOAD 17772340' machine='test1170' command='script' value='set Panel SR 17772340; sleep 500; hold Panel LOAD 250' %}
+
+Step 14: Deposit 000001 at ADDRESS 17772340.
+
+{% include machine-command.html type='clickOnce' label='DEPOSIT 000001' machine='test1170' command='script' value='set Panel SR 000001; sleep 500; hold Panel DEP 250' %}
+
+Step 15: Load ADDRESS register with 200.
+
+{% include machine-command.html type='clickOnce' label='LOAD 200' machine='test1170' command='script' value='set Panel SR 200; sleep 500; hold Panel LOAD 250' %}
+
+Step 16: Set ENABLE and toggle START.
+
+{% include machine-command.html type='clickOnce' label='START' machine='test1170' command='script' value='set Panel ENABLE 1; sleep 500; hold Panel START 250' %}
+
+Step 17: Load ADDRESS register with 300.
+
+{% include machine-command.html type='clickOnce' label='LOAD 300' machine='test1170' command='script' value='set Panel SR 300; sleep 500; hold Panel LOAD 250' %}
+
+Step 18: Examine ADDRESS 300.
+
+{% include machine-command.html type='clickOnce' label='EXAM' machine='test1170' command='script' value='hold Panel EXAM 250' %}
+
+At this point, the DATA register should display `070707`.  You can also use the PCjs Debugger's `rm` command to verify
+the contents of DATA register (DR), or to dump memory location 300 directly (`dw 300 l1`).
