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.
