Raspberry Pi Model A
256 MB RAM, 1 USB Port
The Raspberry Pi (short: RPi or RasPi) is an ultra-low-cost credit-card sized computer board
which was conceived with the primary goal of teaching computer programming to children.
It's also a capable little PC which can be used for many of the things that your desktop PC does,
like spreadsheets and word-processing, it even plays high-definition video.
Or you can use it as a small server for applications like
Or as a gaming or emulation system (for example built into a C64 case with the
Or something entirely different, it's up to you. :-)
The system must be booted from an SD card
card images are freely available), other mass storage devices can be connected via USB.

Model A Notes:
The Model A of the Raspberry Pi is a stripped-down version of the
there is no Ethernet, only one USB port and half the memory
(256 MB instead of 512 MB). What sounds like a disadvantage,
does not necessarily have to be one. The missing features do not only
lower the price, they also lower the board's power consumption: The
Model A only needs about two thirds of the power the
Model B draws, so it's the perfect base for projects that need
to be powered by batteries or solar cells.
