NLS by now had a full set of basic features that have since characterized it and AUGMENT (its commercial successor). E.g.: full-screen, integrated outline and text processing; in-file addressing; in-file and cross-file text or structure manipulation by address; basic repertoire of view-control commands; content filtering; generalized, computer-executable citation links; verb-noun, consistent command syntax with optional use of ultra-fast, concurrent control using the mouse and chord keyset; Included also was a calculator package, integrated into NLS: mouse-selecting operands; totaling columns; inserting accumulator contents at selected locations or replacing selected numbers in a file; executing user macros with pauses and prompts for users to select file variables or provided typed in values.

Put together our home-designed, custom-built displays system to run with the SDS-940. Two custom-built, random-deflection display generators were each time-shared to drive six, small, 5" high-precision CRTs. In front of each of these CRTs was mounted a high-quality, video camera so as to scan the CRT face. These twelve video lines were brought out to our work area, where each work station had a high-quality video monitor for its display. This gave us four sizes of alphanumeric characters, and accelerators vector-graphic figures. The display generators were connected on a Direct Memory Access bus so that switching from one stored view to another occurred essentially in a thirtieth of a second.

Came online with an improved NLS on a time-shared, SDS 940; large swapping drum; special, home-made display system operating from direct-memory access, providing integrated text and graphics, and delivering video to up to twelve workstations out in our laboratory.
