Grid: Pre-MM Informational
From Wise Nano
Informational systems are described in CRN's Three Systems paper.
Some musings about the role of Informational systems can be found in the Nano Dove Organization page.
Open Collector.org's extensive series of articles and comments on open-source hardware is a good place to start if you want to understand the idea behind Open Source hardware, its relation to Free software and some critique.
(Please expand this with more info on Open Source and Free Software, especially as they apply to hardware. There's an open source CPU project, and RepRap, and probably others.)
