Some time ago I obtained a batch of the Tektronix 4050 series newsletter issues. I have scanned these and Al has put them up on bitsavers: <http://www.bitsavers.org/pdf/tektronix/tekniques/> I've also scanned a software catalog for 4050 series: <http://www.bitsavers.org/pdf/tektronix/405x/Supplementary_Software_and_Services_4050_Series_1980.pdf> I have some other Tekniques related items, but they are collections of reprints of articles from specific issues of Tekniques that I've already scanned above, so I considered it redundant. The last issue I had was vol. 8, no. 1. I do not know if there were other issues after that. -- "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!
