I get a lot of questions about how SCRATCH systems are configured, why some things are spec'd, and general costs of these items.
I thought I would answer all the questions in one doc. Its 28 pages long and I am pretty sure it covers everything--including equipping your system for 3D stereoscopic.
You can download it here:
This is a 1.0 doc, so if you have suggestions I am happy to incorporate them into the next revision.
