<ul>
<li>RED - ethernet cable
<li>PURPLE - VGA video cable from laptop to free-standing LCD monitor
<li>GREEN - USB cables. NB the <a href="../i/alfa-awus036ach.jpg">ALFA Awus 036ACH</a> cable is a special one with extra power wires
</ul>
<p>There may <em>ALSO</em> be an ethernet cable between the printer and the Netgear ethernet/wifi device
<h3>Note there are FOUR (4) <em>different</em> power supply bricks</h3>
<ol>
<li>Powerbrick for Dell E4200 Crowley
<li>Powerbrick for Acer Aspire 1 tclaspire3
<li>Powerbrick for R61 Thinkpad Aziraphale
<li>Powerbrick for <a href="../i/wndr4000.jpg">Netgear WNDR4000</a> wifi/ethernet device
</ol>
<p>The Acer Aspire 1 (tclaspire3) and Dell E4200 (Crowley) each have internal, built-in wifi, but we do not use these and they are turned off (with a physical sliding-switch on the case) to reduce confusion.
<p>Aziraphale also has an ethernet socket and can be connected by ethernet cable to the network if convenient and if within-hut wifi is congested.
<p>The mains power plugs are illustrated with 2 pins for clarity, but they are all 3-pin UK-style pugs in reality.

<li>The ethernet cable to the Asus Aspire 1 blue netbook (tclaspire3) goes into the yellow ethernet socket on its own.
<li>The cable to the expo laptop Crowley (and to Aziraphale and the printer if you want) go into any of the block of 4 ethernet sockets in a row together.
<li>We do not plug anything into the USB socket.
