We've discussed Aesthedes here before and I finally got the brochure that came with it scanned and uploaded to bitsavers: <http://bitsavers.org/pdf/aesthedes/Aesthedes_IPEX_88_Brochure_1988.pdf> It clearly shows main system and describes it in general terms (plant not included). Documentation for the Aesthedes is in the scan pipeline. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!
