On February 17th we held a meeting in our continuing effort to reduce the program development demands on the Real Time Computing Complex. In this instance, a group of FCD, FSB and MPAD people reviewed requested modifications to the AS-501 RTCC program in preparation for the AS-502 mission. I could briefly summarize the results by…

Service Module RCS propellant remaining calculations in the CMC
In response to your memo dated January 13, same subject as above, we requested the Guidance and Control Division to carry out a study into the possibility of adding a CMC routine to complete RCS propellant consumed. The results of this study are detailed in the attached memo. As you can see, they have concluded…
AS-258 RTCC Retrofire Time Computation
One step taken in an attempt to alleviate the RTCC program development problem has been to make major reductions in the area of retrofire time computations. Since these deletions have an impact on the Retrofire Controller’s capability and mode of operation, I felt it desirable to report these things in a memorandum devoted solely to…
Summary of what needs to be done to develop flight confidence in the spacecraft computer programs
There has been growing concern in many quarters regarding the adequacy and formality of the final verification testing of the Apollo spacecraft computer program and its interfaces with other spacecraft systems. This concern led to a meeting on March 21st to decide whether everything was really okay and whether something should be done about it….
In which is described the Apollo spacecraft computer programs currently being developed
It is possible to take advantage of the stretchout of the Apollo flight schedule in the manner in which we develop the spacecraft computer programs at MIT. Although the flight schedules have not been fixed, it is evident that certain things can be done which will not only improve the quality and capability of the…
Progress Report – RTCC program development – Review of AS-258(!) requirements
This lengthy memorandum deals with the recently completed review of AS-258(!) RTCC computer program requirements. I hasten to say, many other areas remain to be examined in our effort to bring the over-all job supported by the MCC-H to within acceptable bounds and to assure economical RTCC usage. Of course, specific actions resulting from our…
