This is our collection of all the documentation we've managed to
gather over the decades that bears even a passing relevance to the
spaceborne guidance computers used in the Apollo and Gemini programs ... or at
least all of the documentation I think I'm legally able to give you at the
present time. Some
hints as to where to find such documentation on your own can be found on our
Documentation
Quest page. Our FAQ
page also points out various significant Apollo-centric websites from
which we've taken some documentation, in order to centralize it.
When we're in possession of high-resolution scans, it's our practice to provide
only a reduced-quality but legible version here, but to provide the full
resolution data at
our Internet Archive site. On this page, the links for both are
provided. In general, when any given document has multiple hyperlinks listed,
the first of the links is the recommended one, and the second or third
links provided are generally either much larger downloads, or else are much
lower quality scans.
Finally, while the available documents are provided below in a form which we
think is relatively convenient, we also usually have more information
than we care to clutter up your screen with. For example, we
have the sizes of the downloads, and sometimes the names of the archives from
which we extracted the documents, as well as the name of the person who either
did the scanning for us or else financially supported the scanning process.
You can see this supplemental information by hovering your mouse over the
document title's
hyperlink before clicking the link. Similarly, if you hover the mouse over
a document number
or an author name
,
that's highlighted as shown here, you may be
able to find out the organization that produced the document or with which
the author was affiliated. Unfortunately, this extra pop-up information
only works if
you have a mouse rather than a touchscreen, since you can hover a mouse
cursor but not a finger; but that's life!

Space Guidance Analysis Memos
If you are interested in the mathematical underpinnings of the AGC software,
then this amazing series of memos from MIT's Instrumentation Lab is the place
to look. The memos are in roughly chronological order. It is very interesting
to reflect on the fact that these mathematical memos are often written by the
very same people whose names you find as authors in the software. The AGC
software was written in a time ... or at least a place ... where software was
regarded as the expression of mathematical knowledge as opposed to being a mere
exercise in the expert employment of programming languages and tools as it is
today. It is interesting also to reflect on the nature of the software this
approach produced.

LUMINARY Memos
The "LUMINARY Memos" are internal memos from the MIT Instrumentation Laboratory
dealing with issues of LUMINARY software development, along with
closely-related software branches such as ZERLINA.
Of particular interest,
if you're concerned with the evolution of the AGC software, are the many memos
used to document the changes of the LUMINARY code from one revision to the
next. In theory, if you had all of them, you could come pretty close to using
them to document the complete evolution of LUMINARY, or at any rate from
LUMINARY 4 (memo #22) through LUMINARY 209 (memo #205).
But back to the memos. Over 250 of them are known, of which we've gotten the
majority from Don Eyles's personal collection. The items which are grayed-out
relate to memos about which we have some information but not the actual memos
themselves.

Program Change Requests (PCR) and Notices (PCN)
Program Change Requests (PCRs) were the official mechanism by which proposed
AGC software changes were submitted to the NASA Software Change Board (SCB) for
approval or rejection. I'm not sure what the distinction between a PCR and
a Program Change Notice (PCN) is. Visually they're essentially the same
thing. In any case, the signficance is that since AGC software changes were
governed by them, knowledge of the PCRs/PCNs is of tremendous importance in
tracking changes between LUMINARY and COLOSSUS software revisions ... or
alternatively, of no importance whatever if you're not interested in
understanding the evolution of LUMINARY and COLOSSUS.
The entries below are arranged by PCR/PCN number.

Software Anomaly Reports and Assembly Control Board Requests
In this section, we cover Assembly Control Board Requests and
MIT/IL Software Anomaly Reports. These seemed to act similarly to PCRs and

. This document is the principle (and almost complete) reference for understanding the operation of the AEA CPU per se, the AEA assembly language and assembler, and the operation of the CPU's i/o ports. There are, however, some confusing aspects to the document:- Perhaps the most confusing thing is that while the portion of the document that covers the LEMAP assembler makes it clear that the integer -1 would be encoded in octal as 0777777 (as anyone working with a modern PC would expect), the portion of the document that covers assembly language repeatedly refers to the octal 0400000 as being "-1". (More specifically, the reference on these occasions is to "A0 = 1, A1 thru A17 = 0", where A0 is the sign bit and A1-A17 are the data bits.) In fact, this octal pattern encodes the "largest" 18-bit negative number, namely -131072. In this detail, the assembly-language portion of the manual is thus incorrect.
- Perhaps the most serious omission is that the explanation of division (the DVP instruction) in the case where the dividend and/or divisor is negative is completely lacking and (in the absence of this explanation) I've never figured out satisfactorily how it is supposed to work.

Launch Vehicle Digital Computer (LVDC) and Friends
We have precious little LVDC documentation, and even less LVDC software.
The Wikipedia article on the LVDC at the time I first wrote on this subject
lamented that all of the LVDC software has probably vanished and does not exist
any longer. Fortunately, that has turned out to be false, although there may
be enough truth in it to make us very uncomfortable.

, "Saturn V: Laboratory Maintenance Instruction for LTE, Volume V: Programmable Test Controller", volume V of V, 03/05/1965, by IBM Federal Systems Division
. Buried in Chapter 7 of this volume is the assembly listing of an LVDC program; or rather, the program is for a PTC (Programmable Test Controller) program, but the PTC's central processor is a modified LVDC, and consequently it is essentially an LVDC program. The syntax is very slightly different from that of a standard LVDC program. The principal distinction we are aware of right now is that multiplication and division instructions are replaced by i/o instructions; i.e., multiplications and divisions are performed by some peripheral device rather than by the CPU itself. Because it is not guidance software — it is a self-test program — there is no reason to suppose that there is any restriction for its "export" under ITAR; thus, it is presented in full here. (The document originally came from the NASA Technical Reports Server, and anybody can get it from there without restriction anyway!) The source-code portion of the listing is 170 pages, whereas an LVDC flight program has around 300 source-code pages, so the self-test program is not trivial in terms of complexity.

, Rev 1 August 1965, "Astrionics System Handbook, Saturn Launch Vehicles", missing chapters 10 and 11, 08/01/1965, by IBM Federal Systems Division
. Chapter 11 is particularly relevant to the LVDC, as it discusses the flight software in some detail. Sadly, it does not show any actual sample snippets of LVDC software. You'll notice that we have three different revisions of this document. This earliest revision simply says that chapter 11 is "to be supplied later". One especially-important difference between the later two revisions, other than the fact that the final version has more-legible foldouts and is a much larger download, is that the aforementioned Chapter 11 has been completely rewritten between the 2nd and 3rd revisions: while the earlier version describes the LVDC software used in Apollo 11, the later version describes a new "generalized" LVDC program as used in Apollo 12. Another Apollo 12 vs 11 change is that the flight-sequence table (Chapter 4) differs.

Note that this book contains redrawn electrical schematics of the FCC, though it's unclear the extent to which those schematics are complete.

. The 3 volumes of this document comprise a study that explores using alternate, higher-level programming languages in place of LVDC assembly language. The languages are SPL (Space Programming Language), CLASP (Computer Language for Aerospace Programming), HAL (High-order Assembly Language), and CMS-2 (Compiler Monitor System-2). Of these, HAL looks the most like a modern program language, naïvely speaking, though the report notes that it was the most difficult in which to program. Amusingly also, the language (in spite of its acronym-style name) was actually named by Ed Copps (an AGC developer, not an LVDC developer) for Hal Laning (also of Draper Labs); however the language itself was not developed by the Draper/Instrumentation Labs. The principle significance of the document for us, however, is that the study reveals a lot of detail about the existing LVDC software to which we're not otherwise privy.

Engineering Drawings
There is one significant category of Document Library items which cannot be
contained within the format of this web page. I refer to electro-mechanical
drawings of the CM and LM G&N systems. For example, the AGC
circuit schematics or the drawings of the physical design of the DSKY.
While a few of those drawings appear here, the truth is that the
totality of G&N electro-mechanical drawings in our collection outnumbers the
mere "documents" found here by about 100-to-1. And you can't "browse" through
hundreds of thousands of engineering drawings the way you can with a mere few
thousand documents. Instead, you have to go to our
Electro-Mechanical Page, which provides you with two very-valuable
resources to find the engineering drawings you need:
Everything
If none of the sections above coincides with your special interests, this
section may help. It contains every item in our Document Library,
whether or not those documents were already included in the preceding sections.
(Excluding, of course, G&N system engineering drawings, as covered
in the immediately-preceding section.)
If you still can't find what you need after you've looked in this
section, you might consider using the Google searchbar that appears near the
top of this page. It has the great advantage of searching not only document
titles, document numbers, and authors, but in fact does a complete search of
the text within the documents ... and not only here on this Document
Library page, but for all pages on the Virtual AGC website. Alas, the optical
character recognition (OCR) process that creates the text index is not perfect,
so your search may still fail even if the document you want is present. But
then, what is perfect in this old world?

While the title of this document is undoubtedly correct from the standpoint of IBM Federal Systems Division (the corporate author), the document is more usefully viewed as a complete explanation of the theory of operation of the LVDC, albeit of a very early breadboard version. Topics of Volume 1 include a complete description of the computer's instruction set.

, "Saturn V: Laboratory Maintenance Instruction for LTE, Volume V: Programmable Test Controller", volume V of V, 03/05/1965, by IBM Federal Systems Division
. Buried in Chapter 7 of this volume is the assembly listing of an LVDC program; or rather, the program is for a PTC (Programmable Test Controller) program, but the PTC's central processor is a modified LVDC, and consequently it is essentially an LVDC program. The syntax is very slightly different from that of a standard LVDC program. The principal distinction we are aware of right now is that multiplication and division instructions are replaced by i/o instructions; i.e., multiplications and divisions are performed by some peripheral device rather than by the CPU itself. Because it is not guidance software — it is a self-test program — there is no reason to suppose that there is any restriction for its "export" under ITAR; thus, it is presented in full here. (The document originally came from the NASA Technical Reports Server, and anybody can get it from there without restriction anyway!) The source-code portion of the listing is 170 pages, whereas an LVDC flight program has around 300 source-code pages, so the self-test program is not trivial in terms of complexity.

. Chapter 11 is particularly relevant to the LVDC, as it discusses the flight software in some detail. Sadly, it does not show any actual sample snippets of LVDC software. You'll notice that we have three different revisions of this document. This earliest revision simply says that chapter 11 is "to be supplied later". One especially-important difference between the later two revisions, other than the fact that the final version has more-legible foldouts and is a much larger download, is that the aforementioned Chapter 11 has been completely rewritten between the 2nd and 3rd revisions: while the earlier version describes the LVDC software used in Apollo 11, the later version describes a new "generalized" LVDC program as used in Apollo 12. Another Apollo 12 vs 11 change is that the flight-sequence table (Chapter 4) differs.

Though the title does not say so, this document pertains to using an AGC loaded with AURORA 88 software. The use of AURORA is significant, because it is the last AGC program that includes a full suite of built-in-test code; LUMINARY and COLOSSUS, in contrast, contain only the code for checking the memory-rope checksums. Furthermore, this document is significant in that it provides a better understanding of how to use the test facilities in AURORA. The archive had earlier revisions of the document as well as the ones I scanned, but it appeared to me that they comprised perhaps 800 additional scans, and there wasn't time available at that point to do the extra scanning needed to acquire those earlier revisions.

, "Whole Number Strapdown Computations" or here, 02/1966, by J. C. Pennypacker
. What this document concerns is an alternate type of IMU which does not have a gimballed stable inertial platform the way the actual mission IMU did, but instead was "strapped down" to the spacecraft. In order to use such an IMU, it is necessary to be able to efficiently convert between a coordinate system fixed to the spacecraft and an inertial one, using only AGC integer computations, and this document shows that that is possible, as well as the fact that the strap-down IMU can achieve an adequate accuracy. The author, Jim Pennypacker, also offered me this observation:The document was prepared while I was working for Al Hopkins and Ray Alonso at the Instrumentation Laboratory and describes the analysis of the crux of a proposed backup system if the AGC became overloaded during the LEM trajectory. Although the backup method described was never used, the document shows the type of analysis that went on "behind the scenes" in support of the entire mission.

, "Apollo Lunar Excursion Module, Primary Guidance, Navigation, and Control System Manual" or here, volume I of II, 02/01/1966, by AC Electronics
. If you have looked at our 1972 version of volume 1, you will have noted that roughly 175 pages are missing from that 1972 version. Those 175 pages are the ones discussing the theory of operation of the "control sequences" (microcode of the CPU) in detail. Those pages are not missing from this version! I daresay those pages form the most-extensive discussion of the Block II AGC microcode to which we have access.
ND-1021042
, "Apollo Lunar Excursion Module, Primary Guidance, Navigation, and Control System Manual" or here, volume II of II, 02/01/1966, by AC Electronics
. This volume is notable because it contains a lot of electrical-schematic data for the Block II AGC, relating to stuff like (for example) decoding of the "control sequences" (microcode) of the CPU. Those schematics are not merely a supplemental form of the 1972 version of this document, but also differ from them in some significant ways.

, Rev AJ, "Project Apollo Lunar Excursion Module Primary Guidance, Navigation, and Control System Manual" or here, volume I of II, minus pp. 4-1 through 4-176, 02/01/1966, by AC Electronics
. Unfortunately, pages 1 through 176 in chapter 4 are missing in this scan. Incidentally, note that the table of contents incorrectly indicates where the break between volume I and volume II is (perhaps because the pages were reshuffled when the missing pages were removed), so don't let that confuse you. This missing pages are present in a 1966 version of the document that we also have, though obviously their content may have changed somewhat over the intervening 6 years. Several topics are covered in the missing pages, but the principal topic is the theory of operation of the CPU's "control sequences" (microcode).

.
The ground computer with which the LVDC cooperated was an RCA 110A. "Mathematical Subroutine Manual" sounds very exciting until you find that it means "multiplication", "division", "cosine", "sine", etc. It is still an interesting document, in the sense that it reveals what life was like for the computer programmer in that time-frame. These algorithms are each accompanied by RCA 110A assembly language showing exactly how they were implemented, and give the full theory for each method, duly written up as if the description were a mechanical drawing, with a proper page border appropriate to such a drawing, and accompanied by notations such as the units, scale, and tolerance of the drawing! The image at right (supplied by Dimitris Vitoris) is a photo of an unknown (to me) assembly from an RCA-110A.
7322.3-17
, "Abort Electronic Assembly Programming Reference", 04/1966, by H. L. Stiverson
. This document is the principle (and almost complete) reference for understanding the operation of the AEA CPU per se, the AEA assembly language and assembler, and the operation of the CPU's i/o ports. There are, however, some confusing aspects to the document:- Perhaps the most confusing thing is that while the portion of the document that covers the LEMAP assembler makes it clear that the integer -1 would be encoded in octal as 0777777 (as anyone working with a modern PC would expect), the portion of the document that covers assembly language repeatedly refers to the octal 0400000 as being "-1". (More specifically, the reference on these occasions is to "A0 = 1, A1 thru A17 = 0", where A0 is the sign bit and A1-A17 are the data bits.) In fact, this octal pattern encodes the "largest" 18-bit negative number, namely -131072. In this detail, the assembly-language portion of the manual is thus incorrect.
- Perhaps the most serious omission is that the explanation of division (the DVP instruction) in the case where the dividend and/or divisor is negative is completely lacking and (in the absence of this explanation) I've never figured out satisfactorily how it is supposed to work.

- #67-553, "Application of Redundancy in the Saturn V Guidance and Control System"
- #67-588, "Apollo Guidance, Navigation and Control System Gyro Reliability"
- #67-591, "Advanced Control Systems for the Saturn Launch Vehicle"
- #67-622, "A Performance Study of the Lunar Module (LM) Landing Radar System"
I'm not actually certain of the legality of providing this document to you; it has no correctly formed copyright notice in it, and I believe that in 1967 that would mean it had no copyright at all. In 1989, I think, the law was changed so that for stuff published after then, no actual copyright notice was needed, and any random belch from everybody would automatically copyrighted by them at all times — good job, Congress! — but that foolish concept didn't apply retroactively, and thus didn't apply in 1967; nor do later extensions to copyright law retroactively provide such protection, as far as I'm aware. But I'm not a lawyer, so if you have an informed beef to the contrary, let me know and I'll take the document down.

SIMFAM is a "braid memory" adapter used for ground testing of the AGC, allowing you to use braid memory in place of the AGC's normal core memory. There is a (paywalled) 1966 paper about braid memory in the IEEE Transactions on Electronic Computers, by Aldrich and Alonso. "Braid memory" is apparently a term invented by the authors of the paper. It is a form of "transformer memory". Transformer memory, to quote the paper, "make[s] use of magnetic coupling, linear, or nonlinear, between a set of interrogation lines and a set of sense lines. ... The appeal of such memories is based on the permanence of the information, which is of advantage in control systems, and on the intuitive feeling that it should be possible to build large (about 106 bits), fast (about 1μs cycle time), fixed memories at a cost substantially below that of equivalent core storage," in spite of the fact that the cost of core memory was "rapidly dropping" at that time. In particular, the "braid" variety of transformer memories, based on something called a Dimond switch, could be manufactured by being woven on a loom in order to reduce manufacturing cost. Each "braid" is a string of transformers, with each step of the weaving process adding another transformer to the string, so the speed of manufacture could be increased simply by having the loom simultaneously operate on more braids in parallel. They mention that a 64-string loom was in operation and that a 256-string loom was under development.

If you're really paying close, close attention, you may wonder why all of our information on the COLOSSUS page and this page indicates that the same software was used for the Apollo 15-17 CM, namely ARTEMIS 72, and yet the linked document indicates ARTEMIS 72(REV1) instead. Conversely, the Apollo 15 document linked above indicates merely ARTEMIS 72 without a revision. Sounds different, doesn't it? Well, we don't presently have enough information to resolve this puzzling paradox with satisfying certainty. However, Nik Beug points out that the Operational Data Book actually does list ARTEMIS 72 REV 1 for Apollo 16 as well, while Mike Stewart points out that the AGC's memory modules have the same manufacturing dash numbers for Apollo 15 and 16 (indicating that they had the same software loads stored in them). This lends a lot of credence to the notion that all three of these missions really did have the same software load. Plus, you have other support, such as memos like this one. But whether that software version was ARTEMIS 72 or whether it was ARTEMIS 72 REV 1 is still unclear, and the available data allows it to be argued either way.

. The 3 volumes of this document comprise a study that explores using alternate, higher-level programming languages in place of LVDC assembly language. The languages are SPL (Space Programming Language), CLASP (Computer Language for Aerospace Programming), HAL (High-order Assembly Language), and CMS-2 (Compiler Monitor System-2). Of these, HAL looks the most like a modern program language, naïvely speaking, though the report notes that it was the most difficult in which to program. Amusingly also, the language (in spite of its acronym-style name) was actually named by Ed Copps (an AGC developer, not an LVDC developer) for Hal Laning (also of Draper Labs); however the language itself was not developed by the Draper/Instrumentation Labs. The principle significance of the document for us, however, is that the study reveals a lot of detail about the existing LVDC software to which we're not otherwise privy.
