I am glad it has a question mark after it. I have this recollection that roughly around this same time period, SRI was installing Cisco routers in a testbed for USAEUR. We were working out of Heidelberg (nice place to be). I don't remember or have access to records to know exactly when we did this. Ed Kozel was lead so perhaps it is clearer in his memory (He was at SRI at this time). I was just asked to help with the Cisco routers; and a little later teach some Army personnel about the Internet and networking by preparing and teaching a class for them. My involvement was brief and it served as my introduction to x.25 and of course the Cisco box (I remember reading the X.25 documentation on the plane over). We certainly had lots of interaction with Cisco to make it work okay.<br id="yui_3_16_0_ym19_1_1472616023279_441172"><br id="yui_3_16_0_ym19_1_1472616023279_441173">barbara <br id="yui_3_16_0_ym19_1_1472616023279_441174"><br id="yui_3_16_0_ym19_1_1472616023279_441175"><div id="yui_3_16_0_ym19_1_1472616023279_441152"><span></span></div><div id="yui_3_16_0_ym19_1_1472616023279_440918" class="qtdSeparateBR"><br><br></div><div style="display: block;" id="yui_3_16_0_ym19_1_1472616023279_440922" class="yahoo_quoted"> <div id="yui_3_16_0_ym19_1_1472616023279_440921" style="font-family: times new roman, new york, times, serif; font-size: 13px;"> <div id="yui_3_16_0_ym19_1_1472616023279_440920" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div id="yui_3_16_0_ym19_1_1472616023279_440919" dir="ltr"> <font id="yui_3_16_0_ym19_1_1472616023279_440987" face="Arial" size="2"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> "internet-history-request@postel.org" <internet-history-request@postel.org><br> <b><span style="font-weight: bold;">To:</span></b> internet-history@postel.org <br> <b><span style="font-weight: bold;">Sent:</span></b> Friday, September 2, 2016 12:00 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> internet-history Digest, Vol 106, Issue 5<br> </font> </div> <div id="yui_3_16_0_ym19_1_1472616023279_440924" class="y_msg_container"><br>Send internet-history mailing list submissions to<br> <a id="yui_3_16_0_ym19_1_1472616023279_441242" ymailto="mailto:internet-history@postel.org" href="mailto:internet-history@postel.org">internet-history@postel.org</a><br><br>To subscribe or unsubscribe via the World Wide Web, visit<br> <a id="yui_3_16_0_ym19_1_1472616023279_441238" href="http://mailman.postel.org/mailman/listinfo/internet-history" target="_blank">http://mailman.postel.org/mailman/listinfo/internet-history</a><br>or, via email, send a message with subject or body 'help' to<br> <a ymailto="mailto:internet-history-request@postel.org" href="mailto:internet-history-request@postel.org">internet-history-request@postel.org</a><br><br>You can reach the person managing the list at<br> <a ymailto="mailto:internet-history-owner@postel.org" href="mailto:internet-history-owner@postel.org">internet-history-owner@postel.org</a><br><br>When replying, please edit your Subject line so it is more specific<br>than "Re: Contents of internet-history digest..."<br><br><br>Today's Topics:<br><br> 1.
