A SNAP of an RISC OS 5, running on a Beagleboard device powered by a 600MHz ARM Cortex-A8 processor with a built-in graphics chip, has tipped up on the world wide wibble.

The port developed by Jeffrey Lee is a breakthrough for the shared-source project because it has ported the OS without an army of engineers. The snap shows the Beagleboard and RISC OS 5 booting from a ROM image built with 256M of RAM and reaching a command-line.

According to Drobe, the core of the operating system is able to drive a monitor via a DVI connector and connects with the rest of the universe by a serial port. Lee wants to bring in better USB support so that a keyboard and mouse can be attached, providing all one needs for a cheap computer.

The Beagleboard uses sod all juice and sells for about 100 quid. It is based on an ARM-compatible Texas Instruments OMAP350. It has a built-in OpenGL-compliant graphics processor to speed up 2D and 3D drawing to the screen, a maths unit mainly for processing streams of data, memory card slots, audio in and out, USB and other interfaces. µ
