     <p>In 2025 we  also have "Pulsifer",  "Anathema" and "Barbie" as additional expo laptops. These are is currently running Xubuntu/xfce (not Debian/Cinnamon like Crowley).
 <ul>
   <li>"Barbie" is a pink netbook dating from 2014 which was intended as a replacement to the blue Acer Aspire but which is currently a general use laptop. It is an "HP Stream 11 Notebook", has only 2GB of memory, a 2.16GHz Celeron N2840, 32GB eMMC "drive"  and  is consequently a bit slow - it is donated by Philip Sargent. We have a 12V power supply for this, and it is small and light, so could be relocated to StoneBridge topcamp if that seems to be useful.
-    <li>"Anathema" has a recent solid-state disc and wifi; it has an ethernet socket and (unsually) a working battery of 2 hours, pretty good for a 2011 machine. This is part of the Waddington bequest to expo (actually Michael Waddington's old gaming alienware laptop). It weighs 2kg and we don't have a 12V power supply for it, so it will live at base camp.

(It is an alienware M11x R2 with a wifi module that is incompatible with linux kernels after 5.15.)
     <li>"Pulsifer" is also running Xubuntu/xfce. It has a recent solid-state disc, wifi,  ethernet socket and (unsually) a working battery of about 1 hour. It is configured to run troggle software locally (but not as user 'expo'). It is old and heavy but we do have a 12V supply for it. Installed in potato hut 16th July 2025.
       <li>In 2019 and 2023 we had  "Aziraphale" . This failed to revive in 2025 and is pending repair in Cambridge. It has the identical[Cinnamon/Debian] configuration and survey software installed as Crowley. It is a big, heavy R61 14-inch Thinkpad on loan from Michael Sargent.  (Note that Aziraphale's SD code slot doesn't work).
