I'm teaching a special topics course this fall I'm calling Computing in the Small. Right now, I'm leaning toward conducting it on a platform that runs Plan 9. I'm looking for something based on ARM or MIPS and that has some useful connection to the external world in the form of GPIOs. SPI, I2C, and analog I/O would be nice to have too. Obviously, the Raspberry Pi is a candidate. What are some others? I've seen some code in the source tree for the BBB. Has anyone tried it out to see what is and isn't there? How about the Banana Pi? The SATA port on it is quite appealing. Some of the other options I've been looking at include the VIA APC Rock and Paper, the Phytec Cosmic, the CubieBoard, the Odroid, the Riotboard, and the Wandboard. Has anyone done anything on porting Plan 9 to any of them? Are there others I'm missing that would be good targets for such a class?
Thanks in advance, BLS
