# Copyright: Public domain.
# Filename: TVCSTROKETEST.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: 979-983
# Mod history: 2009-05-13 RSB Adapted from the Colossus249/ file of the
# same name, using Comanche055 page images.
#
# 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.

# NAME STROKE TEST PACKAGE (INCLUDING INITIALIZATION PACKAGE)
# LOG SECTION...TVCSTROKETEST SUBROUTINE...DAPCSM
# MODIFIED BY SCHLUNDT 21 OCTOBER 1968
#
# FUNCTIONAL DESCRIPTION....
# STROKE TEST PACKAGE GENERATES A WAVEFORM DESIGNED TO EXCITE BENDING
# STRKTSTI (STROKE TEST INITIALIZATION) IS CALLED AS A JOB BY VB68.
# IT INITIALIZES ALL ERASABLES REQD FOR A STROKE TEST, AND
# THEN TESTS FOR CSM/LM (BIT 13 OF DAPDATR1). IF CSM/LM,
# IN EITHER HIGH OR LOW-BANDWIDTH MODE, THE TEST IS STARTED
# IMMEDIATELY. IF NOT CSM/LM, PROGRAM EXITS WITH NO ACTION.
# HACK (STROKE TEST) GENERATES THE WAVEFORM BY DUMPING PULSE BURSTS
# OF PROPER SIGN AND IN PROPER SEQUENCE DIRECTLY INTO
# TVCPITCH, WORKING IN CONJUNCITON WITH BOTH PITCH AND YAW
# TVC DAPS, WITH INTERMEDIAT WAITLIST CALLS. NOTE, HOWEVER
# THAT THE STROKE TEST IS PERFORMED ONLY IN THE PITCH AXIS.
# AN EXAMPLE WAVEFORM IS GIVEN BELOW, TO DEMONSTRATE STROKE-
# TEST PARAMETER SELECTION.
# RESTARTS CAUSE TEST TO BE TERMINATED. ANOTHER V68 REQD IF TEST
# IS TO BE RE-RUN.
# PULSE BURST SIZE IS PAD-LOADED (ESTROKER) SO THAT AMPLITUDE OF
# WAVEFORM CAN BE CHANGED. THERE ARE TEN PULSE BURSTS IN
# THE HALF-AMPLITUDE OF THE FIRST FREQUENCY SET IN THE
# STANDARD WAVEFORM. AMPLITUDE IS 10(ESTROKER)(1/42.15),
# NOMINALLY 50/42.15 = 1.185 DEG
#
# CALLING SEQUENCE....
# EXTENDED VERB 68 SETS UP STRKTSTI JOB
# PITCH AND YAW TVCDAPS, FINDING STROKER NON-ZERO, DO A "TC HACK"
# AN INTERNALLY-GENERATED WAITLIST CALL ENTERS AT "HACKWLST"
