I got a complaint that the VirtualAGC GUI program wouldn't fit on a 800×480 7" Raspberry Pi touchscreen.  No kidding!  Well, that's part of a larger problem with it, it appears, in that while the program was attempting to interrogate the screen size and to adjust it user-interface format appropriately, that feature doesn't seem to have been working.  So I've addressed both of those problems in the latest source-code updates in the GitHub repository.  Instead of trying to make adjustments according to the screen size, the VirtualAGC GUI program now depends on command-line options:
  • --radio-buttons — For the largest display screens (with, say, 1024 pixel rows).  Mission selection is the "traditional" way, via radio buttons in the user interface.
  • --dropdown — (The default.)  For smaller display screens (with, say, 720 pixel rows).  Mission selection is in the newer way, via a drop-down list.
  • --squish — For the smallest display screens (with, say, 480 pixel rows).

For use with --squish only, there's also a --maximize command-line option that maximizes the program at startup.

There are no installers for this new program version as of yet, but I'll get around to it sometime if I hear no complaints in the meantime.

Two significant documents were added to the document library:
  • Excerpts from "Apollo 11 LM Timeline Book" (1969), including handwritten notes made, I'm told, by Buzz Aldrin.  It is a notable addition to the collection, because we previously had no final version of the descent procedures specific to Apollo 11, and the procedures in this document differ from those cobbled together from the closest alternatives (Apollo 12 procedures or preliminary Apollo 11 procedures).  This information is necessary, for example, in making simulated Apollo 11 landings in NASSP that are faithful to the 1969 original landing.
  • Level III PGNCS drawings from Grumman.  These are basically souped-up versions for LM-4 through LM-15 of the LM ICD documents we already had, with more-detailed interconnection drawings and pinout information.  They're also significant in a different way, in that they are scans of "aperture cards" from the National Archives in Ft. Worth — a resource I had noted many years ago but had completely ignored, but which is now revealed as a potential treasure chest ... if only we could just figure out what that treasure chest contained so that we could ask for it! 
A new document was added to the document library, "Luminary 1B DAP Preflight Performance Evaluation" (thanks to Hartmuth Gutsche for spotting this doc for us).  It's an evaluation of the results of digital simulation of the digital autopilot of Luminary 116 (Apollo 12).  As it happens, we already had a digital simulation of Luminary 116 in our collection as well, but it was from a somewhat later time and isn't the simulation from which the report was written, presumably.
Two new LVDC-related documents were added to the document library, one sponsored and scanned by Mike Stewart (thanks Mike!), and one cleverly found in the NTRS stash by Nik Beug (thanks Nik!).  These are presently at the top of the LVDC section of the document-library page, and I invite you to read the descriptions there.  However, the more-significant of the two is a study (in 3 volumes), the "Flight Program Language Requirement" document, of the feasibility of replacing the LVDC assembly-language version of the LVDC software with versions in 4 different programming languages.  As a part of this effort, large chunks (but not 100%) of the pre-existing LVDC software were actually ported to those 4 alternate languages, as well as being flowcharted and described in detail.  Thus, though this document does not provide any LVDC code at all, it nevertheless provides much more internal detail about the LVDC software, in almost-usable form, than any other documentation presently available.  Unfortunately, it is not complete enough in itself to allow reconstructing the entire LVDC program.
There are a couple of new LVDC-related documents which Mike Stewart has managed to track down and have scanned on his own dime (thanks, Mike!):
  • "Interface Control Document: Definition of Saturn SA-513/SKYLAB 1 and SA-515/SKYLAB Backup Flight Sequence Program".  Notable for including a pinout of the LVDC and LVDA discrete inputs, discrete outputs, and interrupts, as well as a detailed mission-specific timeline of the theoretical behavior of those signals.
  • "Saturn V Flight Program Development".  Describes the development process for the LVDC software (in a software quality assurance sense), as well as giving a very high-level architectural overview of the software.  Needless to say, most of the specified documentation developed during this process is missing from our collection.  Among the more-interesting soundbytes:  The LVDC software-development process for each launch vehicle, took 61 weeks.
Replaced the photo of the Block I nav-bay DSKY on the Block I page with a much better one.
  • Added 13 COLOSSUS Memos to the document library.  We already had 12 such memos, but they were mixed in with the LUMINARY Memos, so to make them easier to find I created an entirely new section on the document library page exclusively for holding COLOSSUS memos.  Unfortunately, we know that the numbering for COLOSSUS memos goes up to at least 327, so fact that we now have 25 of them still leaves quite a few missing!  The new ones cover COLOSSUS revisions 197 through 221, with a few little gaps.
  • Similarly, I found a couple of SKYLARK Memos memos lurking amongst the LUMINARY Memos, and referenced them in the SKYLARK Memos section of the document-library page.
  • In dealing with the stuff above, I also happened to notice that various mission flight-plan documents which we'd previously been missing — Apollo 7, 10, 13, 14, Skylab, and ASTP —had become available on elsewhere on the web, so I've raided those documents from their original homes and added them to the document library as well.  In other words, nothing new in any larger sense, but now integrated into our document library.  A few other documents were mined and added in the same way ... just look for the icon within the document-library page.  One of the "new" documents, the Apollo Operations Handbook, Block II Spacecraft, isn't really new, but the copy we already had seems to have disappeared without a trace somehow.
  • Found a nice picture of the LVDC, which I've dutifully added to the LVDC page.
