These images show NetBSD used in embedded development. The upper image shows a TS-7200 board equipped with in ARM9 CPU, 32MB RAM, flash drive, 10/100 Ethernet, Compact Flash, USB keyboard, WiFi-USB and serial (COM) ports. The parallel ports are connected to a numeric keypad and a HD44780 display, on which a login can be run, as shown in the lower image. All the code for this is in the main NetBSD distribution, no extra patches required!
