I have been putting off writing this note because it is rather painful. To put it bluntly, the release of Sundisk–the interim earth orbit command module spacecraft computer program–has slipped rather badly. What makes it painful is that it’s not all together clear why it is slipping and we still haven’t found a good way…

Inflight loading of the spacecraft computer erasable memory
Since we have gotten the uplink capability in the LM, some things have been done to make it possible to load the erasable memory in the spacecraft computer while in flight, but possibly not enough….
Verify Sundisk for CSM/LM mission
You know, it’s becoming more and more likely that we will fly a combined command module-LM mission using the Sundisk program. It might be a good idea for you to review the testing that is being done on that program to make sure it can handle that kind of mission, if you have not already…
Deep serious trouble
I realize it’s none of my business, and it’s getting to be less all the time, but you are going to be in deep serious trouble when the MIT contract negotiations for Apollo and AAP hit the fan in the next couple of months unless you have somebody pretty sharp ready to take over for…
MPAD contractual effort provided FSD for software verification
As per your request, I have started to check into the MPAD contractual effort provided FSD for software verification. Jack Williams tells me that they do not have anything like 87 people, but more nearly 65. Furthermore, it is anticipated that this number will be reduced in the near future. At present, Lockheed has 43…
VHF ranging by CSM for ascent monitoring
Attention everyone!! As far as I can tell, everyone wants to get that VHF ranging device on the CM and there’s a big effort going on right now to put together the proposal and justification for it. Most attention to date has been given to its use for rendezvous. It is obvious that it should…
Do y’all need the MIT hybrid facilities for crew training?
I have talked briefly with Pete Woodling about something I probably ought to bring to your attention, too. As you know, we currently have one hybrid simulator in operation at MIT with both a CM and LM cockpit available and we are on the verge of bringing a second facility online….
New/old platform for AS-501
Cline Frasier told me today that the platform in Spacecraft 107 (that is, AS-501) has been replaced again by the one that was taken out several weeks ago. Apparently, there was an intermittent problem in one of the accelerometers. I believe Cline said they have replaced the Z-gyro. This change should be beneficial in terms…
Crew monitoring of the LOI maneuver
On August 3 we had an informal meeting to talk about crew monitoring of the Lunar Orbit Insertion (LOI) maneuver. The subject came up in connection with Jim McDivitt’s preparation for the STAC presentation. I’m writing this note because we tentatively agreed on some fairly basic points with regard to how we might use the…
A new rope module for LM-1 computer
On August 16 General Bolender approved remanufacture of Module III of the LM-1 spacecraft computer program ropes. This was done based on the recommendation of both MIT and MSC technical personnel in order to correct two deficiencies….
