Because FrameMaker is what makes it possible for me to work on this "Kouroo
Contexture" project of mine, I have been attempting to "walk back the cat"
(as they say at the NSA) on the technology of it, exploring the steps of
the development of all the various hardware and software technologies that
have been needed in order to make this project now possible. The result of
my inquiry is at http://www.kouroo.info/general/ElectricWalden.pdf .
FrameMaker comes in at August 1986 -- on page 203 of the Adobe Acrobat .pdf
