# Copyright: Public domain. # Filename: P40-P47.agc # Purpose: Part of the source code for Colossus 2A, AKA Comanche 055. # It is part of the source code for the Command Module's (CM) # Apollo Guidance Computer (AGC), for Apollo 11. # Assembler: yaYUL # Contact: Ron Burkey <info@sandroid.org>. # Website: www.ibiblio.org/apollo. # Pages: 684-736 # Mod history: 2009-05-11 RSB Adapted from the Colossus249/ file # of the same name, using Comanche055 page # images. # 2009-05-20 RSB In S20.1, a DMP DDV was corrected to DMPR DDV. # 2009-05-22 RSB In BESTTRIM, TC PACTOFF corrected to # TS PACTOFF. # 2009-05-23 RSB Prior to the 2CADR at T5IDLDAP, added an # SBANK. # # 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 055 of AGC program Comanche by NASA # 2021113-051. 10:28 APR. 1, 1969 # # This AGC program shall also be referred to as # Colossus 2A # Page 684 # PROGRAM DESCRIPTION ** P40CSM ** EBANK= DAPDATR1 BANK 31 SETLOC P40S BANK COUNT 24/P40 P40CSM TC DOWNFLAG ADRES ENG2FLAG TC INTPRET SLOAD BOFF ECSTEER # IS THIS AN EXTERNAL DELTA V BURN XDELVFLG P40S/C # NO CSTEER = ECSTEER DLOAD # YES CSTEER = ZERO HI6ZEROS P40S/C STODL CSTEER FENG # SET UP THRUST FOR P40 20,000 LBS P40S/F STODL F # P41 ENTERS HERE TIG # ORIGINAL TIG MAY BE SLIPPED BY P40S/SV STORE NOMTIG # SET ORIGINAL TIME OF IGNITION FOR S40.9 EXIT TC BANKCALL CADR R02BOTH # IMU STATUS CHECK P40PVA TC INTPRET CALL S40.1 # COMPUTE VGTIG,UT CALL S40.2,3 # COMPUTE PREFERRED ATTITUDE SET EXIT PFRATFLG P40SXTY TCR SETMINDB -1 # NARROW DEADBAND FOR MANEUVER (EBANK6) RELINT TC BANKCALL CADR R60CSM # ATTITUDE MANEUVER CS ONE # FOR UPDATEVG TS NBRCYCLS TC UPFLAG ADRES TIMRFLAG # ALLOW CLOCKTASK TC P41/P40 TC P41/DSP # P41 P40TTOG CAF V06N40 # INITIALIZE FOR CLOCKTASK WHICH IS CALLED # Page 685 TS NVWORD1 # BELOW TC INTPRET VLOAD ABVAL # FOR R2 VGTIG STODL VGDISP HI6ZEROS STORE DVTOTAL EXIT EXTEND DCA STEERADS # SET FOR UPDATEVG AND TEST FOR STEERING DXCH AVEGEXIT # AFTER AVERAGE G P40GMB CAF P40CKLS2 # (4.1 PROTECTION) TC BANKCALL CADR GOPERF1 TCF POST41 # V34 TCF TST,TRIM # V33 TRIMONLY CS BIT1 # SET MRKRTEMP FOR GIMBAL TRIM (-1) +1 TS MRKRTMP # ENTRY FROM TST,TRIM CAF ZERO # SET CNTR +0 FOR RESTART LOGIC IN S40.6 TS CNTR # +0 SAYS NORMAL ENTRY # +1 (PRE40.6) SAYS RESTART ENTRY CAF ONE TC WAITLIST EBANK= DAPDATR1 2CADR S40.6 CCS MRKRTMP # TEST TO FIND TIME TO WAIT FOR GIMBAL TEST CAF 18SEC # PLUS, DELAY FOR 18 SECONDS TCF +2 # HOLE CAF 5SEC # DELAY FOR TRIM ONLY TASK TC BANKCALL CADR DELAYJOB TC 2PHSCHNG OCT 40026 # 6.2 = PRE40.6(-0CS), CLOKTASK(100CS) OCT 00234 # 4.23 = P40S/SV (PRIO12) P40S/RS CAF ONE TC WAITLIST # P41/SDP EBANK= TIG 2CADR CLOKTASK RELINT P40S/SV TCR E7SETTER # JOB, 4.23 PRETECTS, PREO12 EBANK= TIG # Page 686 TC INTPRET DLOAD DSU TIG SEC29.96 STORE TDEC1 CALRB # RETURN IN BASIC MIDTOAV1 TCF +2 TC P40SNEWM # INTEGRATION TIME GREATER THAN ALLOWED P40SET EXTEND DCA MPAC # DELTA TIME TO PREREAD (INT.INIT.)
