[Tom] is doing a little show and tell with his latest .NET Micro framework based project. He managed to get a prompt-based computer running on a FEZ Cobra board.
A USB keyboard serves as the input device. To give himself a familiar way to navigate and execute programs [Tom] mimicked the functionality of DOS. Above you can see the familiar format of the directory listings as he navigates the data on an SD card. But this goes deeper than changing directories and listing files. He also has access to commands which control peripherals, showing manipulation of the WiFi connection and demonstrating some simple code to show images on the screen. Since the hardware centers around the .NET MF, any compiled binary for that environment can be executed from the prompt as well.
