Pi4 at South West Show

I am posting this at the South West show, using a Pi 4 (4GB) running RISC OS 5.27 (21-Feb-2020), an Elesar WiFi Hat and a USB hub plugged into the power socket. RISC OS cannot yet drive the five sockets (USB and Ethernet) on the Pi circuit board. Task manager is showing 3781424k free with the Iris browser version 1.00 (14-Feb-2020) running! I am using a monitor borrowed from Vince, displaying 1920×1080. The Pi 4 is running at 1500MHz and automatically switching down to 600MHz. It does get rather warm…

I am demonstrating FamTree, SatNav and Data Monitor devices.
