We cannot seem to keep our wiki up. Many pages lost in cyberspace. We hope to get some back. Meanwhile the wiki has gone walkabout. Currently all that can be found is at: http://www.opencircuits.com/SCIL_at_OpenCircuitsMost of it there ( not much yet ) is about the Arduino group and is at: http://www.opencircuits.com/Adruino_SIG . We are working on recovering more and moving it there. When the next move happens it will be posted there. Sorry.
