RaspberryPi , a $35 toy or the next disruptive technology and a possible building block for HPC ? This credit card sized board has a ARM11 processor and 512MB RAM. The board is powered via a micro USB connector. It has two built-in USB sockets, Ethernet and HDMI video. A schematic drawing of model B which I have can be found here . I installed Raspbian Linux, an optimized Debian version for Raspberry, on a 4GB SD card. A cool gadget for triggering thoughts about the future of computing. Enclosed below a few pictures I took, enjoy!
