The expo laptop is called "Crowley". Crowley was rather too ill to be useful during the 2022 expo (being left in the potato hut for 3 years was not a healthy experience) but is now feeling much better... apart from the WiFi which needs a software driver update, but as Crowley is connected to the ethernet cable this is not vital.
In 2023 we will have another general-use laptop (it was also on expo in 2019). This is not connected by any cabling and just uses WiFi. Like the expo laptop it is running Debian and has the same set of software installed - (survex/aven, tunnelx, therion, git etc.) and you login to it using the username "expo" and the usual cavey:beery password. 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 and it is called "Aziraphale". (Note that Azirophale's SD code slot doesn't work). + (survex/aven, tunnelx, therion, git etc.) and you login to it using the username "expo" and the usual cavey:beery password.

Both laptops have had RAM upgrades and solid-state disc upgrades over winter 2022/23. They each hold a local complete copy of expofiles and the expoweb, loser, drawings and troggle repositories but do not have the troggle software configured to run locally, though this could be enabled if necessary.
