PRINTED IN U.S.A. 25-4/67
In this reproduction, every effort has been made to preserve the typography of the original, but the results you see may vary depending on your WWW brouser. Page breaks in the original are marked here with horizontal rules, and the original was printed in blue-green on white cardstock, using what might have ben 6 point News Gothic Light (a small light sans-serif font), with all titles and subtitles centered. Each page was 3.25" by 5.5" (8.3 by 13.3 cm), with a horizontal fanfold presentation.
The 1967 edition corrected typos from the 1965 edition, added 2 pages of figures showing the layouts of the various instruction formats, and replaced material on old PDP-5 peripherals with material on the more modern peripherals that were developed for the PDP-8 in the two years after the original release.
