Moved NLS to a stand-alone CDC-3100, with online disk pack, 16K of 24-bit memory, line printer, paper-tape and punched-card I/O, custom built display. Full structured files, with in-file addressing and uniform text- and structure-manipulation commands.
Published (Rpt-62J) , which included the following: Discussion of how the computer can give aid to the basic communication processes between the human and his external environment (which environment of course includes his kit of computer tools). Clear forerunner of our later User Interface System. Uses example of introducing a chord keyset into a user's environment to bring out specific examples of the NEED-POSSIBILITY REVERBERATION phenomena which was introduced in 1962, (Rpt-62J) , and which is a basic part of all my subsequent strategic thinking. Extensive discussion of USER-SYSTEM, SERVICE-SYSTEM DICHOTOMY, including the characteristics of research in each domain. (CO-EVOLUTION without yet naming it such.) Detailed description of the earliest version of our later FLTS (oFf-Line Text System), and what eventually became our DEX System (Deferred EXecution). Working at a Model-33 Teletype, which makes a punched-tape record of all that is typed. Escape and Command codes embedded anywhere in the text could cause the later "batch" process to correct any previous error or omission, including those in any prior commands. The Model-33 had only one case of alphabetic characters; this process enabled me to designate cases so that the later, processed printout on a two-case Flexowriter (paper-tape driven) would come out with proper alphabetic cases. (I made myself write most of that report this way. And my wife made me move out into the garage to do it because the Model-33 was so noisy. I remember the extra problem of typing with cold fingers.)
Showed real time movie of NLS to ARPA IPTO Principal Investigators at our May 16-17 meeting at MIT. Simple, structure-text manipulations, with very fast concurrent control (mouse and keyset), and very fast computer response (stand-alone CDC-3100). Illustrated the basic difference in perspective between our approach and the prevailing concepts of "time-shared computer support." At that evening's cocktail hour, Bob Taylor told me, "The trouble with you, Doug, is that you don't think big enough." Well, after he dragged out of me a description of what I'd really like, he encouraged me to formulate a proposal for it -- a multi-user laboratory, based on a time-shared machine, to get on with real bootstrapping.
