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_OpenCircuits Much of it there is about the Arduino group and is at: http://www.opencircuits.com/Adruino_SIG . We have since recovered quite a bit more and moved it to open circuits as well. The link http://www.opencircuits.com/Category:SCIL will find most of it.
