# Copyright: Public domain.
# Filename: BURN_BABY_BURN--MASTER_IGNITION_ROUTINE.agc
# Purpose: Part of the source code for Luminary 1A build 099.
# It is part of the source code for the Lunar Module's (LM)
# Apollo Guidance Computer (AGC), for Apollo 11.
# Assembler: yaYUL
# Contact: Ron Burkey <info@sandroid.org>.
# Website: www.ibiblio.org/apollo.
# Pages: 731-751
# Mod history: 2009-05-19 RSB Adapted from the corresponding
# Luminary131 file, using page
# images from Luminary 1A.
# 2009-06-07 RSB Corrected 3 typos.
# 2009-07-23 RSB Added Onno's notes on the naming
# of this function, which he got from
# Don Eyles.
#
# This source code has been transcribed or otherwise adapted from
# digitized images of a hardcopy from the MIT Museum. 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.<br>
## <br>
## 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.

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 ACCOMODATED BY MEANS OF TABLES CONTAINING CONSTANTS (FOR AVEGEXIT, FOR
# WAITLIST, FOR PINBALL) AND TCF INSTRUCTIONS. USERS PLACE THE ADRES OF THE HEAD OF THE APPROPRIATE TABLE
# (OF P61TABLE FOR P61LM, FOR EXAMPLE) IN ERASABLE REGISTER `WHICH' (E4). THE IGNITION ROUTINE THEN INDEXES BY
# WHICH TO OBTAIN OR EXECUTE THE PROPER TABLE ENTRY. THE IGNITION ROUTINE IS INITIATED BY A TCF BURNBABY,
# THROUGH BANKJUMP IF NECESSARY. THERE IS NO RETURN.
#
# THE MASTER IGNITION ROUTINE WAS CONCEIVED AND EXECUTED, AND (NOTA BENE) IS MAINTAINED BY ADLER AND EYLES.

#
# KILLTASK IS USED TO REMOVE A TASK FROM THE WAITLIST BY SUBSTITUTING A NULL TASK CALLED `NULLTASK' (OF COURSE),
# WHICH MERELY DOES A TC TASKOVER. IF THE SAME TASK IS SCHEDULED MORE THAN ONCE, ONLY THE ONE WHICH WILL OCCUR
# FIRST IS REMOVED. IF THE TASK IS NOT SCHEDULED, KILLTASK TAKES NO ACTION AND RETURNS WITH NO ALARM. KILLTASK
# LEAVES INTERRUPTS INHIBITED SO CALLER MUST RELINT
#
