cross-reference other researchers’ additions to the user’s “specialized area” without sorting through irrelevant texts. Bush saw the Rapid Selector as an eventual replacement for card catalogues. Although Bush conquered his basic speed/retrieval problems, the required coding system to access information ultimately proved prohibitively complex. The specialized typewriter for the code-punch was also unworkable. Burke’s text is full of other useful information, follies, and successes that orbit around the development of these pre-digital machines.

The Experiential Typewriter
From Bradley O’Neill
Built by Timothy Leary and Richard Alpert (Ram Dass) in the winter of 1962-1963, Cambridge, Mass. An instrument for recording and charting the psychedelic experience.
“The purpose of the ET was to deal with the ‘words cannot express’ aspects of accelerated-brain experience. The subject could indicate any of various levels of consciousness that they were unable to describe at the moment by pressing the appropriate buttons on the typewriter. The signal was recorded on a revolving drum, much the way temperatures are graphed in meteorological stations.
“After the session, when consciousness was operating at slower speeds, the subject would have leisure to examine the recorded data and describe the sequence of events fully and precisely.”
I’d like a more detailed account of this curiosity, as Dr. Leary does not elaborate in Flashbacks . But it’s definitely dead.

Dead Cryptanalytic Devices of World War II
From Bradley O’Neill
Here are various cryptanalytic machines developed before and during WWII. An “ notes those items for which I will submit more detailed working notes. I am listing all of them here beforehand, for purposes of scope, and to encourage any interested souls.

COLOSSUS - Britain’s special purpose electronic computer to attack the German FISH system.
COMPARATOR - Bush’s tape based-electronic cryptanalytic machines.
COPPERHEAD - OP-20-G [Naval cryptology division] WWII advanced versions of tape-based electronic cryptanalytic machines.
ENIGMA - German encrypting device.
FISH - German teletype-like automatic encryption systems and devices.
FREAK [no joke!] - U.S. electromechanical cryptanalytic machine, WWII.
FRUIT - Special electro-mechanical adding machine built for OP- 20-G by NCR during WWII.
