BENDIX CUBIC TRACKER

BENDIX G-15D and MTA-2 p/o AN/GSQ-29(x1-l) MANUFACTURER Computer Division Bendix Aviation Corporation and Cubic Corporation APPLICATIONS Systems are located at Tyndall Air Force Base, Cape San Blas, and Carabelle, Florida. Tracking Stations at Cape San Blas and Carabelle develop direction cosines measured from x & y base lines for up to three targets, and a frequency correction word for each target transmitter. Information is transmitted via data link to computing site at Tyndall. Data words are automatically converted to G-15D word length and written directly on computer drum. Pro- gram converts direction cosine information to (x,y,z) position and controls automatic position plot of two of the three targets.A command word is generated at the computer site to instruct the program which target trajectories to plot, the change being con- trolled by transmission of a release signal from one target (interce tor) and a burst signal from a second target (missile.Burst also causes the program to compute the vector miss distance from the 3rd target (drone) to the missile in the velocity vector coord- inate system of the drone, and the scalar escape dis- tance between the missile and the interceptor in the MATTS (AN/GSQ-29) coordinate system. Program modifi- cations also permit computation of x, y, z coordinates of any or all targets either on a sample by sample basis (basic sample rate is 20/sec) in non-real time, or at a rate of approximately one sample/sec either real or non-real time. Though the system was basically designed for scor- ing air-to-air missile firings it has also been suc- cessfully used to track missiles fired from the ground. Modifications made to the G-15D to permit on-line data processing were accomplished so as to also per- mit general purpose use of the computer. Part of the high speed punch facility was utilized for an additional long memory line for format conversion and automatic data entry, and the DA-2 circuitry was modified in a minor way to permit data to be written on the M16 and M17 long lines separately.

PROGRAMMING AND NUMERICAL SYSTEM Arithmetic system Fixed point Instruction type Three address Data are organized in the RCA BIZMAC System in the following manner: Seven bits (6 information + 1 parity) comprise one BIZMAC character (63 characters including ten decimal digits, 26 letters, control symbols, and miscellaneous symbols). A variable number of related characters preceded (on the left) by a control symbol comprises an item (corresponding to a word). A group of related items enclosed by control symbols is a message (for handling as a unit on tape). An instruction consists of eight BIZMAC characters interpreted as follows: Operation Variation Addresses A B C B B BB BB BB There are twenty-four basic operations which may be varied by the variation character to obtain approximately 140 distinct combinations. The computer may perform decimal and binary arithmetic operations. Operands are completely variable in length. A 32- character operand limitation is necessary in decimal addition and subtraction where an end-around carry is possible and in multiplication where the multiplicand is also restricted in the same manner. ARITHMETIC UNIT In arithmetic operations, the three addresses are used to specify the High Speed Memory locations of the least significant characters of the operands and the result. Execution time for each of these instructions is variable depending on the number of significant characters in the operands. Control symbols as well as space symbols to the left of operands cause the operations to end. The following timing formulae are available: ADDITION TIME is given by 120 + 40C microseconds, where C equals number of characters in longest operand. This is the formula for addition with positive operands. Formula time is increased when the zero suppression or automatic left justification option is desired or if there is an end-around- carry. MULTIPLICATION TIME is given by 160 + 288N + 145MN microseconds, where M = No. of digits in multiplicand N = No. of digits in multiplier. The constants 288 and 145 in the above formula are average times for reading out characters, and repetitive additions are determined by the magnitude of the digits in the multiplier. Division is programmed, and the time varies with the type of division program used, as well as with the characters of the operands. The timing formulae shown above include instruction staticizing time as well as transfer-of-data time to and from the memory.

Basic construction of the arithmetic unit is vacuum tube- diode. There are no programmed rapid access registers outside of the 4,096-character High Speed Memory. Basic pulse-repetition rate is 500 KC throughout the Computer. Arithmetic operations are primarily serial although pairs of characters (one from each operand) are read from memory in parallel.

Government Sample Ordnance Tank-Automotive Command System has the following complement: Tubes 30,000 Crystal diodes 70,000 Magnetic cores 35,000 Transistors 200 Separate cabinets 470 CHECKING FEATURES Parity The BIZMAC code is designed in such a fashion that each character of information contains a redundant parity bit for even parity checking. The various devices in the system contain hardware for extensive utilization of this feature. In the Computer, information circulating internally or transferred to and from tape is checked for parity. Adder Comparison The adder forms two sums (the second by using complements of the operands). These sums must be equal, or comparator alarms are registered. Tape Checks Input checks are provided to assure that the proper sequence of control symbols is sensed (marking the beginning and end of messages). The first character read in is checked to see that it is one of three permissible control symbols. An output check is provided by an echo signal, which is used to determine that writing on tape has properly taken place. Dual recording on magnetic tape is provided. Fourteen channel tape permits the duplicate storage of each bit. Program Control Checks are provided to insure that instructions are properly located, that drum switching is correctly completed, and that the flow of basic machine cycles is correct. Instruction Characteristics Facilities which are present for use in programs include a verify instruction for data comparison, and an overflow alarm usable with decimal arithmetic instructions. Computer Stop-Rollback Switch This device is used to reduce manual intervention when certain types of errors are detected: parity, adder comparison, programmed verify and overflow, control-symbol sequence incoming from tape. When the switch is in the rollback position a transfer of control will be made automatically to a specific

These are Jump to "permanent" instruction, Jump to "built-in" subroutine, and Set index and jump to main memory. Registers and B-boxes The machine will have 63-one microsecond access index registers, addressable by the A, B, and Y addresses of the instruction words. The parameter bits of the instruction word are used to indicate variations of the basic order type. All three arithmetic registers are 68 bits. Tag bits enter these registers only on the logical instructions and the shift instruction if it is cyclic or is a Boolean shift. On arithmetic orders, the tag bits are saved in a separate three bit register and the three extra bits in the arithmetic registers are used for checking overflow. Thus the range of numbers in the arithmetic unit is -128 < N < 128. Add and subtract are performed the same as for normalized arithmetic, except the result is never shifted left at the end of the operation. Before multiply is done, the coefficient that has the largest absolute value is normalized. There is no left normalization after the operation. Thus the result has approximately the same number of significant digits as the operand that had the smaller number of significant digits. It does tend to retain an average of about two or more bits than it should, however. Before divide is done, both operands are normalized but the number of divide steps performed is reduced accordingly so that the result has approximately the same number of significant digits as the operand that had the smaller number of significant digits.

The arithmetic unit only is constructed of 1727 vacuum tubes of 4 types, 853 transistors of 3 types, 46,500 diodes of 2 types and 1,600 pulse transformers of 1 type. Arithmetic mode Parallel Timing Synchronous Logical events are controlled by a five-phase clock, permitting decisions at a 5 Mc rate. Operation Concurrent Indexing and control will be concurrent with arithmetic operations. Except for arithmetic or Boolean compare instructions, the test overflow instructions with P33 = 1, or any arithmetic order that stores in any index register or stores in the location of the next instruction, the machine always gets its next instruction from the memory while it is doing the previous instruction. If this next instruction is one of the control and indexing orders, it is immediately done, unless it is an input-output order or a test overflow order. If it is done, it proceeds to get another instruction and do it, if possible. Thus almost all of the control and indexing orders can be done concurrently with the arithmetic or logical orders. Only the arithmetic and logical orders require the use of the main arithmetic unit of the machine. All types of input-output orders can be done concurrently with other instructions. Automatic interlocks are provided so as to prevent timing conflict. Reference to a main memory position within the range of either an input or output instruction will halt the computer until the input or output transfer has occurred at that memory position. The computer is released as soon as the transfer of that particular word has been made and does not wait for the entire transfer to be completed. There is no interlock on the index memory when it is used as index registers. Only the effective addresses A, B, and Y are conflict checked. The programmer can easily make the computer wait until such a transfer is complete by using the last address in the index range of the snout order in the A, B, or C addresses of a dummy order. An input-output instruction is not started until the previous arithmetic instruction is finished, hence the last arithmetic result may be included in the range of any input-output order. As many as five input-output orders can be operating concurrently with computing and with each other. There is a separate trunk for reading cards, punching cards, using drum, and two separate trunks for using magnetic tape and all five of these trunks can operate concurrently.

An alarm light is turned on and computation is stopped by a forbidden combination (binary-coded decimal digit 10 thru 15) in the A, B, D, and R Registers, the Address Register, Control Counter, and Shift Counter. Inspection of the registers on the Control Panel indicates the failure location. An alarm stops the computer if the storage cell counted does not contain all zeros at the start of each drum revolution. This prevents information from being recorded on or read from incorrect locations on the drum. An audible alarm indicates excessive rise in exhaust air temperature in the computer cabinet. After a pre-set interval, up to 15 minutes, DC voltage will be shut off if the temperature stays at or above a predetermined level. Optional: The marginal voltage test panel facilities selective lowering of voltages in registers and control section, which, in conjunction with test routines, can detect marginal components before they give trouble in actual operation. Supervisory test panel on front of computer has extensive controls and check features, including access to any flip-flop for manual setting, substitution of manual or low frequency pulse operation for the drum clock, and a switch panel which allows maintenance personnel to force abnormal register behavior and to inhibit certain normal checking functions for diagnostic purposes. Contents of all registers are displayed simultaneously at all times.

POWER, SPACE, WEIGHT, AND SITE PREPARATION Manufacturer Power, computer 16.5 KVA Volume, computer 181 cu ft Area, computer 28 sq ft Weight, computer 3,175 lbs Special flooring is recommended for the Burroughs 205 System to handle the combined and individual weight of the units and to accommodate the intercabling. Since all units of the system are designed to have their cables enter from underneath their cabinets, raceways or ducts in the floor are recommended to accommodate the inter-cabling. There are three types of floors which have been found to be completely satisfactory: (1) raised floor, (2) existing floor with built in cable raceways, and (3) existing floors with cables underneath enclosed in metal conduit. The area should provide adequate lighting, some acoustical treatment, communication equipment, and convenience of access to the equipment. The power line should not be serving other heavy equipment which may generate excessive voltage fluctuation. Vibration from such heavy machinery in the vicinity of the system could shorten the life of certain sensitive components. There should be adequate space to accommodate the necessary refrigeration equipment, and the area should lend itself economically to complete air conditioning. Amount of air conditioning depends upon size of computer system installed. For every 12,000 BTU/hour generated by the system one ton of refrigeration is recommended. Environmental condition should also be taken into consideration. The floor load in the computing center can range from 175 to 200 lbs per sq ft and up to 250 per sq ft under the power supply unit. The site selected for the computing center must have a floor which can support the combined weight of the system as well as the localized weight at each leveling point on the units.

Outline of lease policy Basic monthly rental entitles the customer to a maximum of one hundred and seventy-six (176) hours of use time during each calendar month. Use time of each system component in excess of one hundred and seventy-six (176) hours will be chargeable at the rate of forty percent of the hourly basic rental. The hourly basic rental is 1176th of the basic month- ly rental. Extra use charges will be computed to the nearest half hour. Use time is defined as follows: "The time during which each component is in operation exclusive of preventive or remedial maintenance time. When com- ponents are inter-connected and programmed to operate as a system, all such components shall be deemed to be in use for the entire period when any part of the system is operating. Components which are not includ- ed in a given program will not have use time accumu- lated against them even though the components are inter-connected." The rental rate is effective at or from the date installation of the equipment is complete and remains in effect thereafter until terminated by either party upon ninety (90) days written notice. The lease price includes personal property tax and insurance coverage on the machines; all additional taxes are paid by the lessee. Machines under lease may be pur- chased at any time at the prices in effect at the time such option less a credit of forty percent of all rental charges (excluding taxes) are paid on the actual equipment purchased, provided that such credit shall not exceed a maximum of sixty percent of the purchase price in effect. The 8860 Plan for Rental of Burroughs 205 Data Pro- cessing Systems The reduced rental charges applicable to system orders under the provisions of this option will be sixty per cent of the basic monthly rental charges and will entitle the lessee to use the system up to eighty-eight hours per calender month. Use of the system in excess of eighty-eight hours per month shall be subject to an extra charge at an hourly additional use rate of one per cent of the regular monthly charge. Use time is defined as the time during which the system or any components thereof is in operation, exclusive of preventive or remedial maintenance time: when system components are normally inter-connected the sum of the regular monthly charges for these components is to be taken as the regular monthly charge for the system in determining the hourly additional use rate. The customer at his option may convert from the 8860 rental plan to the normal one hundred and sev- enty-six hour rental plan. When this conversion is made the customer may not revert to 8860. Use of the system for more than one hundred and twenty-eight hours per month would make it advantageous for him to convert. Burroughs will provide the necessary parts and ser- vice to maintain the equipment in good operating condition as required during its regular business hours, eight a.m. to five p.m., Monday through Friday excluding holidays. Burroughs 205 Data Processing System may be of any configuration, the 8860 plan applies only to on-line equipment. The tape perforaterand verifier model 454, the numeric code converter model 460, and other simi- lar equipment used off-line' must be rented at normal monthly rental rates. The Burroughs input-output equipment, models 289, 292, and 293 are not offered at reduced rental. Custom engineering devices on which charge has been established must be rented at the full rental rates. Debugging allowance for 8860 is limited to twenty- hours of machine time. Maintenance/Service Contracting Burroughs will keep the machines in good operating condition. All costs of maintenance (except for ribbons and supplies) will be borne by contractor un- less the required maintenance is due to the fault or negligence of the lessee. Burroughs shall provide maintenance service during all periods of operation. Upon mutual agreement, contractor will assign "on site" service engineers. The lessee will provide adequate storage space for spare parts, and adequate working space including heat, light, ventilation, electric current and outlets, for the use of the service engineers. These facili- ties will be within a reasonable distance of the ma- chines to be serviced and will be provided at no cost to contractor. Preventive (scheduled) maintenance for each machine will be furnished on a schedule which is mutually acceptable to the lessee and Burroughs and which is consistent with the operating requirements. Burroughs will always be responsive to the mainte- nance requirements of the lessee. All remedial (un- scheduled) maintenance will be performed promptly after notification to contractor's nearest service location that a machine is inoperative.

Automatic editing provided by the format bands on Cardatron buffer drums, as well as freeing of the central computer as soon as information is transferred. This allows input, output, and processing simultaneously while card machines operate at a maximum rate. Independent search for permanently addressed blocks on magnetic tape, which allows processing of results of previous search while current search is going on. Ability to read from magnetic tape, update information, and write back on the same tape in the same position. Provision of high speed through quickaccess loops, which allows straightforward sequential coding and does not require complicated placements of instructions or data for minimal access. The Burroughs Card Input Unit, Model 293, with a reading rate of 300 cards per minute is now available for use with the Burroughs 205 Cardatron. Also available is the Burroughs Card Output Unit (Model 292), which operates at 100 cards per minute, either reading or punching, and the Burroughs Line Printer, Model 289, which operates at the rate of 150 lines per minute. Editing features of the Cardatron system are complemented by the use of this Cardatron Input Output Equipment. Required storage environment for.magnetic tape includes temperature 60 degrees to 80 degrees; relative humidity 40% to 60%; magnetic fields, not to exceed three oersteds; radiation, where radiation is not dangerous to people; dust proof containers; reels placed in plastic containers and stored on edge of container in a vertical position; must be rewound on a 205 Tape Storage Unit. Minimum storage life, one year when stored as outlined above. BNS Unique system advantages include the Cardatron System and Magnetic Tape Bin File. Tapes retained in computer room in plastic cases,. numbered with 3x5" card index of usage and condition. Computer system is supplemented by 10,000 point EAM (IBM)installation, run on a two-shift basis. USN HO Washington The 205 is extensively buffered by the Cardatron system for both input and output. The 205 provides several input- output media, i.e. punched card, punched paper tape, magnetic tape (in & out) plus printed tabulations (out). Duplicates of all data tapes are filed in a building other than the computer building; all data tapes (originals and duplicates) are stored in areas with [ 1/2 page not included ]

Reels of magnetic tape (250 ft or 2500 ft) are assigned to research personnel having a need for same. They are used only by the individual to whom assignment has been made. All reels of magnetic tape are stored in the temperature and humidity controlled computer room from which they are never roved. Tape labelling is left to the discretion of each individual. WE System I Outstanding features include a large tape storage capacity (permanent - "Datafiles") - 6,000,000 words, large drum storage capacity - 4,080 words, IBM Code Burroughs code conversion and format editing devices, independent magnetic tape search, and photo electric reader, for program entry (540 digits per second). Magnetic tape handling: all tapes and duplicates stored in metal cabinets in same room as computer (72oF - relative humidity 45,%). Tape labeling variable, depending on ,job. Usually a revolving numbering system with ,job title identification. External labeling shows job title and reel number. FUTURE PLANS ARGMA A second Burroughs 205 with same exact configuration is scheduled. for installation in the OML Division, Armyy Rocket & Guided Missile Agency, Redstone Arsenal, Alabama. USA CC It is anticipated that a new computer will be installed in the near future. Selection of new computer has not been established at this time. BNS Approval for installation of one IBM Type 1401 Data Processing System (no tapes) has been requested from the Bureau of Ships. Upon installation of this system in June/July 1961, sizeable reductions in data processing costs will be effected and the system will be utilized to augment existing equipment on an interim bais pending completion of necessary studies to ,justify a new transistorized, core storage, central shipyard computer (the feasibility study for this system was submitted to BuShips on 21 July 1960). New major applications under consideration for application to the 1401 and subsequently to the new centralized computer include total supply inventory, cost accounting, and production planning and control. Ultimate goal of data processing personnel is the development of a shipyard-wide, fully integrated data processing system in which source data automation techniques will be exploited to the maxim= possible extent, and the master file so designed that common data will be reused where possible to effect desired reports in the shortest possible time and in the most economical manner. USN HO Washington It is planned to replace the present 205 with a higher speed computer. USN MDL Future plans call for purchase of IBM 704 System to replace our present system. This replacement will greatly increase our productivity and make available more time for new applications. USNOL Corona Plan to replace the present computer system with an IBM 7070 System. USN USL Consideration for the purchase of IBM 704 System, configuration to be Core Memory 8K, Drum Memory 8K, Magnetic Tape Units 4, Card Reader, Card Punch, Online Printer, Paper Tape Input and Off-line Magnetic Tape to Printer. NAS A ARC At the present time a building is being designed for the Ames Research Center, primarily for housing computing equipment and the associated staff. This new facility should be occupied during the first half of 1961. At this time a medium size Honeywell 800 System will be leased to take over all functions of the Burroughs equipment and perform additional scientific calculations. ATIC W-P System to be replaced by an IBM 7090. B & W Lynchburg There is some talk of doing on line experimental data reduction either with another smaller machine or by creating a data link to connect the laboratory devices to the computer (12 miles distant). A larger machine capable of doing two dimensional nuclear codes would be considered if the work load justified it. Burroughs Replacement of present card input-output equipment with Burroughs equipment. Burroughs Model 289 Line Printer 150 lines/min Burroughs Model 292 Output Unit 100 cards/min Burroughs Model 293 Input Unit300 cards/min CCC Add automatic floating point and magnetic tape (Data- file) in the immediate future. G ICA Delivery schedule for the next two years is as follows: May 1960 305 RAMAC May 19611401 - 4 tapes Nov 19611401 - 4 tapes Dec 19617070 - 8 tapes Feb 19621401 - 4 tapes Plans have not been finalized with respect to the balance of the applications among the equipment. There are no definite plans for retiring our Burroughs 205. KSC Replace with Univac Solid State 80. Add hourly payroll processing for 7,000 employees. LA We are currently conducting a feasability study of the new family of medium scale computers in the microsecond range. We have narrowed the field down to IBM, RCA and NCR in the medium price range. This study was started because we need a faster computer for our current work load, magnetic tape for future applications, and the economy of the new series of computers. NNG Feasibility study to determine more computer power in progress. PP & LC Within next several years, increased requirements.may be greater than present computer capacity. When need for more capacity is foreseen, an additional or a more powerful computer will be ordered as found most feasible at that time.
BRL 1961, BURROUGHS 205, start page 0145
USS Probable acquisition of Cardatron for punched card input/output within a year. Probable acquisition of larger computing system within three to five years. WE System I No new applications are planned for this system as the full two shift capacity has been reached. All programming and planning effort is being expended on a new IBM 70701401 Tape System due for installation August 1961. At this time all ,jobs will be cut over in their present form. After cutover, new applications and amplification of present systems can be undertaken, because of the greater speed and capacity of this new system. _U of N It is expected that in the near future the following items of hardware will be added to the initial equipment: a floating point device, magnetic tape and a Cardatron. U of D A Model 500 Punched Card Converter, IBM 523 Scary Punch, and. IBM 514 Reproducing Punch is to be added. INSTALLATIONS U. S.

Outline of Sale Policy A standard Burroughs Corporation sales or rental agreement will be executed at the time of sale or lease. Prices are F.O.B. Pasadena, California. Sales, use or other taxes imposed directly on the sale or rental of Burroughs machines by Federal, State, or local governments will be borne by the purchaser or lessee. Maintenance service for purchased equipment on a continuing or on-call basis is available by contract through a staff of qualified service engineers stationed in major cities across the country. Maintenance service for leased machines is provided as required to keep the equipment in good operating condition. Rental agreements are effective for one year from the date installation of the equipment is complete, and remain in effect thereafter until terminated by either party upon 90 days' written notice. Machines under lease may be purchased at any time at the prices in effect at the time the lease is executed, less a credit of 40% of all rentals paid, up to a maximum of 60,% of the purchase price. Guarantee and Installation Policy Except for expendable items, such as tubes, diodes, fuses, lamps, and neon indicators, all equipment is guaranteed for one year against defective material or workmanship. The purchase or lease of Burroughs machines includes the following: 1. Necessary manuals which describe operation of the equipment. 2. The services of trained personnel to supervise installation in the customer's plant. 3. Prescribed training of the customer's employees by qualified Burroughs instructors in programming, operation and maintenance procedures and techniques. The Burroughs "10070 Plan" for rental of 220 Data Processing Systems The 10070 Plan, is a new approach to the rental of major scale data processing equipment. To qualify for rental under the "10070 Plan", a system which normally rents for at least $15,800 per month must be ordered ($11,100 per month under "10070"). As long as monthly usage remains at 100 hours or less, only 70% of the monthly rental must be paid. The lessee has the option to convert to the regular 176-hour standard rental plan at any time his work load demands the additional time. However, once the lessee has exercised the option to convert to regular 176-hour monthly contract, he may not revert back to the "10070 Plan". The "10070 Plan" applies to only on-line equipment, excluding the High Speed Printer System, and the Input/Output Cardatron Equipment, however the monthly rental of any off-line equipment equipment may count toward the minimum total rental of 15,800 per month. Use time for the 100 hours is defined as the time during which the system or any components thereof is in operation, exclusive of preventive or remedial maintenance time: when system components are normally inter-connected the sum of the regular monthly charges for these components is to be taken as the regular monthly charge for the system in determining the hourly additional use rate. Burroughs Corporation will provide the necessary parts and service to maintain the equipment in good operating condition as required during its regular business hours, eight a.m. to five p.m., Monday through Friday excluding holidays. Maintenance/Service Contracting Burroughs will keep the machines in good operating condition. All costs of maintenance (except for ribbons and supplies) will be borne by contractor unless the required maintenance is due to the fault or negligence of the lessee. Burroughs shall provide maintenance service during all periods of operation. Upon mutual agreement, contractor will assign "on site" service engineers. The lessee will provide adequate storage space for spare parts, and adequate working space including heat, light, ventilation, electric current and outlets, for the use of the service engineers. These facilities will be within a reasonable distance of the machines to be serviced and will be provided at no cost to contractor. Preventive (scheduled) maintenance for each machine will be furnished on a schedule which is mutually acceptable to the lessee and Burroughs and which is consistent with the operating requirements. Burroughs will always be responsive to the maintenance requirements of the lessee. All remedial (unscheduled) maintenance will be performed promptly after notification to contractor's nearest service location that a machine is inoperative. If contractor is unable to restore a machine to good operating condition and the machine remains inoperative for a continuous period of 24 hours during scheduled work days of the installation from the time the lessee notifies contractor that the machine is inoperative, and it is determined that (1) the machine became inoperative through no fault or negligence of the lessee, and (2) the lessee's production requirements were interfered with as a result of the machine breakdown, Burroughs will grant to the lessee a credit for each hour the machine eas inoperative. Such credit shall be 1176th of the monthly charge for the inoperative machine plus 1176th of the monthly charge for an interconnected machine not usable as a result of the breakdown; provided, however, that the credit granted for each machine shall in no instance exceed 130th of the monthly charge for the machine in each 24 hour period. Burroughs will use its best efforts to assist the lessee in procuring service on equipment compatible with that used by the lessee, to meet emergencies such as a major breakdown, conversion from one system to another, unforeseen peak loads, etc. The lessee, at its option, may accept or reject the offer of use of emergency equipment. If accepted, the cost of such services, if any, will be arranged on an individual installation basis.
