The digitization # was performed by Paul Fjeld, and arranged for by Deborah Douglas of # the Museum. Many thanks to both. The images (with suitable reduction # in storage size and consequent reduction in image quality as well) are # available online at www.ibiblio.org/apollo. If for some reason you # find that the images are illegible, contact me at info@sandroid.org # about getting access to the (much) higher-quality images which Paul # actually created. # # Notations on the hardcopy document read, in part: # # Assemble revision 001 of AGC program LMY99 by NASA 2021112-61 # 16:27 JULY 14, 1969 # Page 731 ## At the get-together of the AGC developers celebrating the 40th anniversary ## of the first moonwalk, Don Eyles (one of the authors of this routine along ## with Peter Adler) has related to us a little interesting history behind the ## naming of the routine.

## It traces back to 1965 and the Los Angeles riots, and was inspired ## by disc jockey extraordinaire and radio station owner Magnificent Montague. ## Magnificent Montague used the phrase "Burn, baby! BURN!" when spinning the ## hottest new records. Magnificent Montague was the charismatic voice of ## soul music in Chicago, New York, and Los Angeles from the mid-1950s to ## the mid-1960s. # BURN, BABY, BURN -- MASTER IGNITION ROUTINE BANK 36 SETLOC P40S BANK EBANK= WHICH COUNT* $$/P40 # THE MASTER IGNITION ROUTINE IS DESIGNED FOR USE BY THE FOLLOWING LEM PROGRAMS: P12, P40, P42, P61, P63. # IT PERFORMS ALL FUNCTIONS IMMEDIATELY ASSOCIATED WITH APS OR DPS IGNITION: IN PARTICULAR, EVERYTHING LYING # BETWEEN THE PRE-IGNITION TIME CHECK -- ARE WE WITHIN 45 SECONDS OF TIG? -- AND TIG + 26 SECONDS, WHEN DPS # PROGRAMS THROTTLE UP. # # VARIATIONS AMONG PROGRAMS ARE ACCOMMODATED BY MEANS OF TABLES CONTAINING CONSTANTS (FOR AVEGEXIT, FOR # WAITLIST, FOR PINBALL) AND TCF INSTRUCTIONS.
