CASE NO. 2 The RLC ci rcui t
This is a case where the higher order derivative must be reduced to a first or-der derivative. The reduction method can be outlined as follows:
1. Set Yl equaJ to the fi rst order derivative
"2. The derivative of Yl is the second derivative and it can be expressed in terms of the differential equation.
3. The second equation, describing variable Y2 is the first order derivative, that is, d/dt(Y2) ::: Yl
The same type of approach will reduce hi.gher oder equations.

THREE-BAR AND FOUR-BAR LINKAGE SYSTEM WITH PLOTTED OUTPUT
r? '
/1,
l.- "I.;. jA mathematical model of a linkage system is controlled by an array of inputs to plot out the path of the linkage intersection point. In addition, the system simulates turning the entire mechanism about a major axis. The output of the system has yielded some very interesting designs.
In conjunction with this report, a list-oriented free field floating point input program has been developed. This routine enables the control program to modify only specified iteITls of the system input. Under break character control, an autoITlatic ite rative procedure can be set up.
Some sample outputs are shov:. n in the enclosed photo .

The System Reference Library
o
I'm Gordon Goesch, Product Publications Manager, IBM, San Jose. There is a Product Publications group at each of the Development Laboratories, as well as a Programming Publications group at most of them. And, of course, there is a department in White Plains that prepares Application descriptions. These groups all provide input to the System Reference Library, and that, rather than my own department, is the subject of myThe System Reference Library is the current method of indexing and clas-sifying system manuals, and is the latest of a series of different methods, each designed to solve the problems that the previous methods couldn't handle. Problems created by new and very complex systems. This method isn't perfect either, as you are well aware, but we are certainly
I don't know how knowledgeable you are about our publications; therefore, for the benefit of the new members and also for the updating of the veteran
Slide #1 Library. BOL contains a great amount of information, the major portion of which are publications for users of our equipment.
You are probably interested in establishing a library for only one system type,
and for only a particular configuration of that system.
Considerable thought and effort was spent in the design of the Systems Reference Library, to allow IBM people and customer people to select that material that is of particular interest to them.
Each SRL is an encyclopedia for a particular system -with separate publications for the major subject areas.
It consolidates all the basic reference literature necessary for you to: Plan, Program, Install, and Operate that system.
o
Currently there are 13 System Reference Libraries, ranging from the 1130 to the System 360 - and of course each system has its own separate Bibliography.
Each Bibliography is actually an Index of all the current publications about a specific system. In it, publications are listed both by subject code and by machine number -and it contains abstracts describing each available publi-cation. (We will discuss subject code a little later. ) Now, how do we update the Bibliography?
Each Bibliography has its own Newsletter (green for easy identification) and it is issued monthly (when there are changes). The Bibliography Newsletter updates the Biblio-graphy by:
1. providing titles and abstracts of new publications 2. providing form numbers of Technical Newsletters 3. Listing type 1 programs and their latest
modifi-cations, and
4. Listing obsolete form numbers.
U'T!'¥'w-"wnWWWY$"
Actually, the Bibliography newsletter is a current" Accumula-tive Index of Publications and Programs" available for a given system.
To keep the Newsletter from getting too large, Bibliographies are periodically scheduled for revision - when that occurs, the information from the current newsletter is merged into Bibliography.
An additional source of information is the "Data Processing Techniques" (DPT) Bibliography (Form F20-8172). It
indexes a series of publications of techniques for Study,
Analysis, DeSign, Implementation, Programming, Documen-tation, Installation, Operation, etc.
This slide shows some of the DPT manuals ..
Another excellent Index for your use is the KWIC Index of Marketing Publications (Form 320-1621).

Slide =11=17
It is published quarterly and updated by a monthly TNL.
The KWIC Index is based on an abbreviated 30-position
publication title - listing and cross-referencing publications

by the important words in the title. for a single publication - "Programs for Petroleum Engineering"
and here, the same publication listed by machine number and by form number.
The latest KWIC Index was prepared from 11, 546 publication titles which generated 29, 122 listings.
Actually, the KWIC Index lists many publications other than SRL publications, such as Executive Guides and Brochures,
tools and techniques manuals, applications manuals and (;) briefs, educational material.
Therefore, to start a System Reference Library, it is
necessary that you work with your IBM representative, using the three key publications we have talked about, the:
1. Bibliography and its Newsletter' 2. the DPT Bibliography
3. KWIC Index of Marketing Publications
You can select and build your own reference library to support your system.
However, please do not order your publications by writing to Product Publications (the address shown on the manual) or our Distribution Center in Mechanicsburg, as it will only delay the order. You must order through your local
c
The file number performs two functions: the first part specifies the system (s) number; the last two digits the Subject Code. The Subject Code structure is a group of two-digit numbers (00-99) assigned to the various system components, e. g.
00 General System material; Bibliographies, System 01 this publication is about Special and Custom features.
Incidentally, these subj ect codes are all defined by their use in Part I of each Bibliography.
The form number is self explanatory; however, the form number suffix indicates the edition, or editorial level, of the publication.
Because of the nature of computers and of the computer industry, it is frequently necessary to make changes to
manuals. Just as green newsletters update the Bibliography, so do regular newsletters update any publication in the
Library.
In most cases TNL packages are made up of an identifying cover page and replacement change pages for the parent publication - when you receive such a TNL you merge it into its parent manual and throwaway the old pages.
InCidentally when you order a publication you will auto-matically receive the latest technical level copy as well as all the outstanding TNLs against that publication.
This slide shows the upper right hand corner of a TNL. It indicates how the TNL identifies itself with its parent publication.

/~3.
Slide #23 parent publication it updates (and it is form-number-suffix sensitive)
Below that is the TNL's own number, publication date of the TNL, and the form numbers of any previous TNLs outstanding against the parent publication.
InCidentally, all page replacement TNL pages carry similar identifying information.
Outstanding TNLs are incorporated into the parent publi-cation when it is being revised. TNLs may also be merged into the parent publication when it is being reprinted.
Information regarding the technical level of a publication, and the TNLs that may have been merged into it, is printed inside the front cover of each SRL manual.
This slide shows a manual, a corresponding TNL, and a green SRL newsletter. With this combination on hand you have all the publishing reference you need for the parent manual.

I' •Keep in mind that the best SRL publishing information source is the green SRL newsletter, because it not only updates its
0
own parent publication (the bibliography) but also lists all the existing publications that are current for that system as well as their outstanding TNLs.
and of course that each major system has its own bibliography.
Thus, the SRL system keeps you well posted on what is in (current) and what is out (obsolete) for an effective library.
Basically,you have at your disposal a "living-doll" of a library system.
How can you get new manuals and TNLs after you have established your library?
a. If you desire, you may continue ordering specific publications through the IBM Branch Office.
b. However, you may pr~fer to use the SRL Sub-scription Service that the System Reference Library offers.

revised manuals, and newsletters, directly to you without having to go through the IBM Branch office each time.All Systems Reference Library manuals listed in SRL Bibliographies under subject codes 00 through 50 are available by profile.
This distribution of publications according to profile is designed to provide you with a basic, master library tailored to your needs.
Application Program manuals, Student Texts, Data Processing Techniques manuals, Course Description Bulletins, and other miscellaneous documents (except padded forms) listed in SRL Bibliographies under subject codes 60 to 99 can be subscribed to by form number.
In addition, and this is new, revision service on multiple copies of SRL's and PLM's under subject codes 00 through 50 may be ordered by form number.
Here's how it works:
To convert existing Revision Service Subscribes, special pre-printed conversion forms are being sent to all the sales offices. The salesman will review your needs with you and establish your "profile", which is basically a description of your system and your applications. You should also identify those publications you, want in multiple quantities and order the quantities you need. The salesman sends the form to the Distribution Center and you are in business. You will receive as many copies of the form-numbered publications as you ordered, and any new or revised (or newslettered) form that fits your profile.
For new subscribers the system is the same except that pre-printed forms obviously won't be used.
Now, you are all set, you know what is available, you know how to select the publications, and you know where to get them.

Slide =11=31 knowledge about your system through the IBM Systems Reference Library. I hope that the result of all this, will make you as happy as the man in the next slide -careful planning of your library may help!
Most of you have probably noticed the Reader's Comment Form that is appearing on the back of many manuals these days. Some of you may have filled one or more out. The response to these has often been very gratifying and we appreciate it.
This form is self-addressed and post-paid and will be directed to the correct publications group. As a reminder, our whole-hearted effort in providing first rate publications support for your systems.
