SheevaPlug - Wikipedia, the free encyclopedia: "The SheevaPlug is one of the first 'Plug computers' to be available on the market. It features a 1.2GHz Marvell Kirkwood 6281 ARM-compatible CPU (aka Feroceon). The device has already been accredited as an 'NSLU2 killer' due to its low price (and the discontinued status of the NSLU2). 
The SheevaPlug comes supplied with Ubuntu 9.04 ARM build. The SheevaPlug has been supported since Kernel 2.6.27 and is currently shipping with 2.6.30-rc5  Marvell offers a development kit to assist in the development of software for the platform. The kit includes the GCC cross-compiler for ARM and a method for accessing the device's debug console. The debug console is accessed over a direct serial link via a connection to its onboard mini USB JTAG. The debug console supports access from either Linux or Windows."
