Table 1-1 lists in general terms the applications normally supported by the vari- ous models. Each model is discussed in detail throughout this manual to give the user a full working knowledge of his particular equip- ment. It is suggested that a new user read and become familiar with the contents of this man- ual before attempting installation and opera- tion. Operating techniques are very simple and can be readily learned in a few minutes. Model numbers, if not known, can be found on the identification tags, located on the bottom of each unit. Each calculator is comprised of two major units; the keyboard, and the electronic pack- age. The “K” suffix toa keyboard model num- ber signifies a conventional keyboard, a “KT” suffix signifies a trigonometric keyboard, and a “KR” suffix signifies a trigonometric key- board with radian input. The electronic pack- age portion of the calculator bears an “E” suffix for non-simultaneous operation and an “SE” suffix for simultaneous operation. Sec- tion 2 of this manual explains the many in- stallation arrangements possible with Wang calculators. Two accessories, a card programmer (CP-1) and an item counter (IC-1) are available for use on any model in the 300 Series. The card programmer is an especially helpful addition for users that perform repetitive operations. It is connected in series between the keyboard and the electronic package and uses standard 80-step data cards that can be readily punched by the user for his particular programs. The item counter proves its value for users that re- quire item counts, operational step monitor- ing, and function monitoring. It is connected to the keyboard, and like the card programmer can be placed on the user’s desk for conven- ience. Detailed descriptions and operating in- structions for each are included, where ap- plicable, throughout this manual. Section I Introduction Table 1-1 300 Series Models and Applications Model Range of Applications 300 Business to simple engineering calculations. 310 Statistical and business calculations. 320 Scientific, engineering, statistical, and business calculations. 320KT Same as Model 320 with trigonometric capabilities for sine, cosine, arc sine, and arc tangent (input in degrees). 320KR Same as Model 320KT except input in radians. 360 Same as Model 320 with four additional random-access storage registers. 360KT Same as Model 360 with trigonometric capabilities for sine, cosine, arc sine, and arc tangent (input in degrees). 360KR Same as Model 360KT except input in radians. 362 Same as Model 320 with twelve additional random-access storage registers or twenty-four half-registers. 362KT Same as Model 362 with trigonometric capabilities for sine, cosine, arc sine, and arc tangent (input in degrees). 362KR Same as Model 362KT except input in radians. 1.2 MODEL 300 ELECTRONIC CALCULATOR The Model 300 Calculator is the basic model in the 300 Series. Operational capabilities in- clude addition, subtraction, multiplication, chain multiplications, divisions, reciprocals, percentages, automatic extensions, weighted averages, etc. Two independent adders, one on each side of the keyboard, provide storage and recall capability. Accumulating switches are provided for automatic accumulation of entries and /or multipliers in the right adder, and pro- duct or extension accumulations in the left adder. All operations, as well as number and deci- mal input, are initiated by the keys on the key- board. Display is provided by *% in. high glare- free indicator tubes that display the readout in conventional form (algebraic sign and nu- merical value with properly positioned deci- mal point). 1-2 A “clear display” key enables the user to clear the display without destructing the con- tents of the accumulators, etc. A “‘clear all” key is provided to clear the accumulators and Figure 1-1. Model 300K Keyboard. display when desired. A “‘change sign” key, when depressed, reverses the sign of the num- ber in the display. Both simultaneous and non-simultaneous operations are available with this model. The installation section of this manual depicts the many methods of installation and operation. All accessory equipment can be utilized with the Model 300. 1.3 MODEL 310 ELECTRONIC CALCULATOR The Model 310 provides all the features and functions of the Model 300 plus two addition- al operational keys for the functions of X and X?. Both operations are performed instanta- neously and furnish direct 10-digit readout in the display window. The accumulation switch- es, in addition to their normal functions, pro- vide DX, DX?, VY, VY?, U(X+Y), D(X), BV, and 2x. The accumulated totals are recallable to the display at any time. Both simultaneous and non-simultaneous operations are available with the Model 310, as well as accessory equipment. Figure 1-2. Model 310K Keyboard. 1.4 MODEL 320 ELECTRONIC CALCULATOR The Model 320 provides all the features and functions of the Model 310 plus two addition- Section 1 Introduction Figure 1-3. Model 320K Keyboard al operational keys for the functions of log.x and eX. Both operations are performed instan- taneously and furnish direct 10-digit readout in the display window; the accuracy for log.x functions is 12 digits, the eX accuracy is 11 digits. The addition of the log functions allow the user to generate logs and exponents to any base, simplifying calculations in many areas of applications. Chain multiplication and di- vision, using cumbersome numerical values, can be readily manipulated by using the log and antilog approach. Techniques for using the log keys are discussed in the operation section of this manual and can be readily learned in minutes. Both simultaneous and non-simul- taneous operations are available with the Model 320, as well as accessory equipment. Trigo- nometric keyboards for single keystroke gener- ation of sine, cosine, arc sine, and arc tangent in degrees or radians are also available in this model. 1.5 MODEL 360 ELECTRONIC CALCULATOR The Model 360 provides all the features and functions of the Model 320 plus four storage registers with capacity for 14-digit numbers and algebraic signs. Eight additional keys have been added to the keyboard to furnish random- 1-3 Section 1 Introduction to differentiate between the registers.The exe- cution of the register operation keys prior to depressing the address key prevents the nor- Figure 1-4. Model 360K Keyboard access recall and store operations. The ‘“‘clear all” function does not affect the registers and numbers previously put into any storage regis- ter will remain until a new number is stored. The ability to store constants, intermediate answers, Or multiple results allows the user to perform many calculations without re-entering the data. The Model 360 is available with trig- onometric keyboards for degree or radian in- puts. Simultaneous electronic packages are available with this model. 1.6 MODEL 362 ELECTRONIC CALCULATOR The Model 362 provides all the features and functions of the Model 320 and has a keyboard arrangement similar to the Model 360. The four extra registers of the latter are replaced by 12 registers, each with a 14-digit capacity (plus sign and decimal storage). Each register may be used as a storage register or as an ac- cumulator. When used as storage, any register may be “split” into two “halves”, each with independent store and recall capabilities. Ca- pacity of the “half registers”’ is six digits, sign, and full 10-place decimal location. Two key- strokes are required to command the registers (i.e., store full and 9). The number keys 0-9, clear display key, and change sign key are used 1-4 mal key functions. Figure 1-5. Model 362K Keyboard The Model 362 is available with trigonomet- ric keyboards for degree or radian inputs. Simultaneous electronic packages are not a- vailable with this model. 1.7 TRIGONOMETRIC KEYBOARDS Six trigonometric keyboards are available in the 300 Series (320KT or 320KR, 360KT or 360KR, and 362KT or 362KR). Two configu- rations are available depending on user’s re- quirements; the KT models accept angular in- put in degrees, the KR models accept angular input in radians. The keyboards are identical to the non-trigonometric keyboards with the exception of four additional keys (SIN, COS, SIN’, TAN“). All trigonometric keyboards operate with theirassociated standard electron- ic packages. Results are readily obtained by entering the angle, sine, or tangent and depressing the ap- propriate key. The answer in degrees and frac- tions is read in the display eliminating the need for table references and error-prone tedious Section 1 Introduction Table 1-2.

Model 360KT Keyboard interpolation. Table 1-2 lists the range of input variables and accuracies. Trigonometric functions utilize both ac- cumulators, as well as the log registers; there- fore, these registers should not be used before trigonometric calculations. If extra storage is necessary for other operations, a Model 360 or 362 Calculator with additional storage reg- isters (not affected by trigonometric calcula- tions) should be chosen. 1.8 MODEL CP-1 CARD PROGRAMMER The Model CP-1 Card Programmer is a com- pact, general-purpose plug-in accessory which enables automatic calculator operations when used with any 300 Series Keyboard. It reads 80-step 2-digit octal program codes, corres- ponding to keyboard operations, from punch- ed tab cards. Figure 1-7. Model CP-1 Card Programmer A Card Programmer is series-connected be- tween the electronic package and the keyboard by use of the attached 12-foot cable and side- panel connector. One CP-1 may be used with Section 1 Introduction each terminal of the electronic package (up to four for a simultaneous electronic package). The CP-1 may be used in conjunction with a trigonometric keyboard on the same electron- ic package terminal, but cannot initiate trig programs under card program control. Exten- sion cables up to 50 feet in length may be used to interconnect the CP-1 with an electronic package. The CP-1 is enclosed in a cast housing with START and CONTINUE push button controls at the top. Bifurcated contacts and a high me- chanical advantage lever closure mechanism provide reliable reading of static tab cards. Built-in electronic circuits are solid-state, and of plug-in construction. An auto/manual switch on the side of the programmer enables the user to examine and verify each program step when initiating a new program. Programs are recorded using pre-scored tab cards, prepared using a port-a-punch and sty- lus. The sequence of manual keystrokes re- quired to execute the problem are determined and recorded. The corresponding program code bits are sequentially punched out on the pre-scored tab cards. A “stop” code provides the means for entering the variables into a program. An excellent library of programs is furnish- ed free with each CP-1. 1.9 THE MODEL IC-1 ITEM COUNTER The Model IC-1 Item Counter is an optional accessory that can be used with any keyboard in the 300 Series. It provides the user with the means for obtaining a ready reference to the number of addition, subtraction, multiplica- tion, division, square root, and square opera- tions, or any combination of these operations in any calculation. The capacity of the counter is 10,000 less 1 (9,999). Operation is controlled by a series of select- or switches. When a function count is desired, the appropriate switch is placed to the up position. A reset control is provided for re- setting the counter to zero between calcula- tions. The counter has an attached 18-inch cable that connects to any 300 Series Keyboard that has been modified with an IC-1 mating con- nector. Connectors are factory installed on keyboards shipped with item counters, other keyboards can be returned to the factory for retrofitting. Figure 1-8. Model IC-1 Item Counter 1.10 MISCELLANEOUS ITEMS T Connector. — A T Connector is a small device used to connect two keyboards in paral- lel to one terminal of an electronic package. T Connectors may be arranged to allow the op- eration of four keyboards from one non-simul- taneous electronic package or up to sixteen from one simultaneous electronic package. When the latter setup is used, one keyboard of each group of four may be operated at any one time. PT Connector. — A PT Connector is similar to a T Connector except one input side has priority over the other side. MX Multiplexer. — The MX Multiplexer is a rack-chassis that contains solid-state logic and plug-in switching relays for automatic inter- connection in any combination of sixteen key- boards to a single simultaneous electronic pack- age. Any four of the sixteen keyboards can be simultaneously used. MX Connector. — The MX Connector is a T connector used with the MX Multiplexer to en- able up to sixteen additional keyboards to be connected to the multiplexer for occasional use. Filters and Transformers. — A line filter is offered to reduce interference from devices which impress electrical noise on the AC pow- er line. Examples are some mechanical calcu- lators and X-ray machines. Two sizes of isola- tion transformers are also offered for the same purpose. A voltage control transformer is of- fered for excellent voltage regulation of vary- ing or consistently low-voltage power lines and moderate line noise suppression. Before order- ing these devices, it is suggested that the user contact the nearest Wang office for an on-the- job trial, rarely are they needed. Carrying Cases. — A ruggedized “suitcase” is offered for transporting non-simultaneous electronic packages, and an attache case is Section 1 Introduction available for carrying one or two keyboards and a card programmer. Cables and Connectors. — Cable may be ordered in bulk, with separate connectors, as required. 30-conductor AWG No. 26 wire, in a0.003 in. O.C., 80°C PVC Jacket is furnished. Male connectors are offered for connection to the electronic packages and female connectors for the keyboards. Connector assembly dwg. no. 5315 gives soldering information. If cables are installed within or behind walls, a surface mounting box and wall mount cover plate are available to provide a neat termination of the extension cable near the user’s desk. Standard lengths of extension cable with attached con- nectors are available in 25 foot incremental lengths ranging from 25 feet to 200 feet. Port-a-punch. — The Port-a-punch, manu- factured by IBM, is recommended as ideally suited for low-cost preparation of CP-1 pro- gram cards. A stylus is included with the Port-a-punch. Program Pads and Cards. — Pad-form work- sheets for preparation of programs, retention of program running instructions and descrip- tion are available. Also, prescored 80-step tab cards for use with the CP-1 Card Programmer are available in various quantities. Section 1 Introduction THIS PAGE INTENTIONALLY LEFT BLANK Section 2 Installation SECTION 2 INSTALLATION 2.1 GENERAL This section includes installation setup, and pre-operating information necessary for trou- ble-free operation of Model 300 Series equip- ment. It is suggested that the new user read and become familiar with the information con- tained herein before attempting to operate the equipment. Full utilization of the equipment with the many possible configurations can be readily understood by careful perusal of the arrangement diagrams. The relatively few pre- cautionary requirements should always be fol- lowed to eliminate possible equipment mal- functions. 2.2 UNPACKING AND INSPECTION Carefully unpack your equipment. Inspect all units for shipping damage; if damage is no- ticed, do not proceed. Notify shipping agency. Check equipment received against purchase or- der. Decals specifying model numbers can be found on all Wang equipment. The decals are normally located on the bottom of the units. 2.3 SPECIAL INSTALLATIONS If special installation requirements are de- sired (i.e., over-the-ceiling or between-the- wall), contact your Wang representative for de- tailed instructions. Users who prefer having the cables in walls or ceilings must furnish their own electrician. For such installations, Wang Laboratories can provide suggestions on ex- tension cables, location of electronic packages, and environmental accessories needed to make the Wang equipment function effectively. If actual soldering work (i.e., connectors to ex- tension cables) is requested of Wang Labora- tories, time and travel charges will be billed at standard rates. 2.4 LOCATION OF ELECTRONIC PACKAGES Electronic packages, both simultaneous and non-simultaneous operate efficiently at room temperature. Because a certain amount of heat accumulates in the package when power is ap- plied, it is advisable to place the unit in a loca- tion where there is some free air movement. Unventilated storage cabinets, closets, etc. are undesirable; cases have been known when a very close environment caused temperatures inside the electronic package to rise above 130° F. This temperature would present an op- erating limitation to the equipment and can cause malfunctions to occur. 2.5 EQUIPMENT INTERCONNECTING ARRANGEMENTS Many different hookup configurations are possible with the 300 Series equipment line. Figure 2-1 illustrates in block diagram form some of the most common configurations. Be- cause of design parameters, limitations are im- posed on some configurations. If in doubt about special arrangements not included here- in, please contact your Wang representative for further information. Connector shape allows only one method of mating; note configura- tion of connectors. Secure connectors with spring locks. 2.6 SPECIAL CONSIDERATIONS Keyboard extension cables cannot be placed in a conduit which is already occupied by an AC power line. Conduits should be used to pro- tect extension cables which are subjected to indefinite exposure outdoors, extreme tropi- cal conditions of saturation, humidity, and high ambient temperatures. Section 2 Installation For multiple-outlet installations, the non- simultaneous electronic package, or each of the four output channels of the simultaneous package, is limited to a two-tier, three T- Connector maximum setup for branching to four regular keyboard outlets. A maximum length limitation of 200 feet should not be exceeded when using extension cables between standard keyboards (not KTs) and electronic packages. The branching maximum is limited to a two T-Connector, three outlet setup whenever a CP-1 Card Programmer, or a KT Trigonometric Keyboard is attached. Further, either of these items must be connected to a first-tier or pri- mary T-Connector. This rule also applies when a priority PT-Connector is used. Due to power requirements, the extension cable from the electronic package to the CP-1 Programmer or to the KT Trigonometric Key- board is limited to a 50-foot maximum length. Caution must be taken to prevent overload- ing a channel with more than one KT Trigo- nometric Keyboard or more than one CP-1 Card Programmer. For maximum safety in con- trol of outlets, the T-Connectors should be located close to the electronic package. Using T-Connectors, the keyboard turned on first will go “on line”. Displays on the re- maining outlets will not light up. In all T- branched connections, each keyboard user should establish a courtesy habit of turning off the keyboard after use. A priority PT-Connector permits one of three interlinked keyboards to preempt the electronic package for immediate use and in- terrupt any unfinished work initiated on an- other keyboard. The electronic package sup- ports only one priority keyboard on the first tier of a PT-Connector. Two additional normal outlets can be used. When a CP-1 Card Programmer and a KT Trigonometric Keyboard are used together, 2-2 they must be directly coupled to the electronic package. Four outlets are the maximum amount available from any one channel of an electron- ic package (please remember KT and CP-1 restrictions). A simultaneous electronic package can al- ways be substituted for a non-simultaneous electronic package. When a high numbered model of electronic package is installed, it can accept keyboards of a lower numbered series as well as its own numbered series. A lower numbered electronic package can operate with a higher numbered keyboard (except 360K with 320E), but added key functions of higher unit will not be opera- tive. Because of design characteristics, a Model 360K Keyboard and a Model 320K Keyboard should not be attached to the same T-Connector. When this condi- tion exists, the Model 360K Keyboard loses the use of its extra storage registers. Two Model 360K Keyboards attached to a T-Connector would function normally. A Model 360K Keyboard should not be attached to a Model 320 Electronic Package; erroneous indica- tions may occur. 2.7 TURN-ON PROCEDURE After interconnecting the various units of the system, peruse your equipment for power switches. Place all power switches to OFF. CAUTION: The preceding procedure is ex- tremely important. Damage to the equipment can result if power is applied to equipment with power switches ON. Connect units that require AC power to ex- ternal AC power outlet. Three-pronged con- nectors for common grounding are provided on all Wang equipment for your safety. IMPORTANT — Place power switch of elec- tronic package to ON before placing remaining power switches to ON. This sequence should always be followed when turning on the equipment. If asimultaneous electronic package is used, depress PRIME switch (red button) on top of package. This purges all the circuits and resets the circuits for operation; this also turns on a flashing signal light on each keyboard display. Depress CLEAR ALL switch(es) on key- board(s). This switch should always be de- pressed before beginning any set of calcula- tions to clear accumulators, registers, etc. of any previous data. The keyboard display should show +.0000000000. Equipment is now functioning and ready to solve calculations. Refer to Section 3, Operat- ing Instructions for detailed instructions. Section 2 Installation 2.8 TURN-OFF PROCEDURE Turn-off procedure is simple but important. Always place keyboard power switch(es) to OFF before disconnecting keyboards from electronic packages. This simple precaution prevents any transistor damage that could arise from a voltage surge caused by a sudden dis- connection. Electronic packages can remain ON without damage. If a CP-1 Card Program- mer is used, the keyboard should be discon- nected before the card programmer. Likewise, the reverse is advisable for connection policy. REMEMBER!! Always make certain that the keyboard is turned off before connecting or disconnecting equipment. Also, heed turn-on order; electronic package first, then the keyboard(s).

Interconnecting Arrangements (contd. ) 2-6 Section 3 Operation SECTION 3 OPERATION 3.1 GENERAL This section explains, by using typical ex- amples, the operation of each keyboard func- tion. It is suggested that the reader actually per- form the sample problems on a keyboard to gain experience and insight into the techniques used for the many calculations. 3.2 PRECISION and ROUND OFF Every register on the 300 Series contains 14 digits (not including decimal point). Although they are not normally seen on the display, the 14 digits’ full precision is used in the operation of addition, subtraction, and calculations of logs and exponentials. In multiplication, divi- sion, and computing of squares and square roots, the calculations are performed to 14- digit precision, and then rounded to 10 digits for the display. 3.3 BASIC REGISTERS All 300 Series Calculators contain three bas- ic kinds of registers: a work register (display window), two adders (left and right), and the product or log register. The basic keyboard is comprised of the black adder keys, the blue log register keys, and the white numeral keys. A distinctive feature of the Wang calculating logic is the ability to generate logarithms and exponentials. This ability is most readily seen in the e* and log.x keys. While the use of this type of logic adds considerable basic power to the calculator, the explanations in this section do not consider the arithmetic operation from the point of view of logarithms. Multiplica- tion, division, squaring, and extracting square roots are all considered as normal algebraic calculations. 3.4 KEYBOARD ARRANGEMENTS Table 3-1 lists the keys associated with the various models in the 300 Series calculator line. Operating examples start with the keys that are common to all models and progress through the series to the explanations of the keys pe- culiar to the more sophisticated models. Each sample problem has been carefully chosen to allow a fuller understanding of the calculator operations. Users that require additional in- formation for special applications are urged to contact their local Wang Representative for assistance. The ““Code”’ columns following the various keystroke commands are listed for fa- miliarity and are associated with the card pro- gramming capability discussed in Section 4.

REMARKS This operation adds the number in the display to the contents of the left adder. The answer remains in the adder and also is shown in the display. OPERATION / EXAMPLE Add using the right adder. REMARKS This operation adds the number in the display to the contents of the right adder. The answer remains in the adder and also is shown in the display. OPERATION / EXAMPLE Put 2 in the left adder. REMARKS This operation clears the adder circuit and puts the 2 that is in the window into the left adder. The 2 will remain in the window and the adder. OPERATION / EXAMPLE Put 9 in the right adder. REMARKS This operation puts 9 in the window, then clears the adder before putting the number into the adder. Notice that the adder can be cleared after the number has been indexed in- to the display. The + (AR) operation places the number in the window into the adder. The number remains in the display and also in the adder. Section 3 Operation OPERATION / EXAMPLE Add 2 + 5.7 using the left adder. REMARKS After the adder is cleared, the number 2 is in- dexed into the window and placed into the adder by the + AL operation. The 5.7 is then indexed into the display. Remember that the 2 is stillin the adder. By depressing the + (AL) key again, the 5.7 is added to the 2 in the add- er to produce the sum of 7.7. Note that the answer is in the window and also in the adder. OPERATION / EXAMPLE Add 9 + 4.5 in the right adder. REMARKS This is the same sequence of operation as the previous addition operation using the left add- er. Answer is 13.5 as shown in the display. OPERATION / EXAMPLE Subtract using the left adder. REMARKS This operation subtracts the number in the display from the number in the adder. The re- sultant number appears in the display with the appropriate algebraic sign.
