[IAEP] OLPC-SF February meeting

[Sameer Verma]

For all those who were at the OLPC SF meeting today,  Andres Aguirre
tells me that the CAD design will be updated in a few days to the
newest version. The current design is at
http://www.fing.edu.uy/inco/proyectos/butia/mediawiki/index.php/Mec%C3%A1nica_Buti%C3%A1_V1.8

The rest of this email has links to the logic board and the vendor
that makes these online.
