These source-code files were from the printout at the MIT Museum, with many thanks
to Deborah Douglas, the Museum's Curator of Science and Technology, for releasing
it to us. The printout was digitally photographed by Paul Fjeld. A team of
volunteers transcribed the source code manually from these images or, where
appropriate, modified already-transcribed but similar source Colossus 249 (Apollo 9)
source code to agree with the images from the printout. Note that the page images
presented online are of reduced quality, and that higher-quality images
are available. Report any conversion errors or legibility
problems in page images to info@sandroid.org.

021243,001022: # THIS SUBROUTINE COMPUTES THE REQUIRED INITIAL VELOCITY VECTOR FOR
021244,001023: # A TRAJECTORY OF SPECIFIED TRANSFER TIME BETWEEN SPECIFIED INITIAL
021245,001024: # AND TARGET POSITIONS. THE TRAJECTORY MAY BE EITHER CONIC OR
021246,001025: # PRECISION DEPENDING ON AN INPUT PARAMETER (NAMELY, NUMBER OF
021247,001026: # OFFSETS). IN ADDITION, IN THE PRECISION TRAJECTORY CASE, THE
021248,001027: # SUBROUTINE ALSO COMPUTES AN OFFSET TARGET VECTOR, TO BE USED
021249,001028: # DURING PURE-CONIC CROSS-PRODUCT STEERING. THE OFFSET TARGET
021250,001029: # VECTOR IS THE TERMINAL POSITION VECTOR OF A CONIC TRAJECTORY WHICH
021251,001030: # HAS THE SAME INITIAL STATE AS A PRECISION TRAJECTORY WHOSE
021252,001031: # TERMINAL POSITION VECTOR IS THE SPECIFIED TARGET VECTOR.
