PROGRAMMI NG AND NUMERICAL SYSTEM Internal number system Binary digits/word Binary digits/instruction Instructions/word Instructions decoded Arithmetic system Instruction type Instruction word format 4 4 6 Order Para- Index type meter Binary 68 + 4 parity 68 1 33 Fixed and floating point Three-address , 14 6 a-Address Index 14 ~-Ad- dress 6 14 Index y-Address Number word format 3 Tag I 60 Sign Binary Point Number word format I 3 Tag 1 Sign Operation Concurrent Indexing and control will be concurrent with arithmetic operations. Except for arithmetic or Boolean compare inst~uc tions, the test overflow instructions with P b 1, 33 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 irtput-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 canputer 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, ~, 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 inout 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 tother. ~here 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. Fixed Point 1 4 Binary Point Floating Point 52 Coefficient I 8 ] Biased Exp of 16 Automatic built-in subroutines In addition to the standard set of jump instructions, three more jump instructions have been included which will be used in connection with the "permanent" storage of "built-in" subroutines. 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, ~, 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 t~e 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.

ADDITIONAL FEATURES AND REMARKS Manufacturer See Burroughs 205 for further details. U. S. Army OTAC Outstanding features are ability to use the digital computer for data input to the analog computer and digital plotting board for direct off-line plotting of problem variableB as required. Adopted procedures for magnetic tape labelling, storage, shipping, and protection from humidity, temperature and physical, electrical, fire, or other damage include: Programmers collectively maintain the necessary tape files. Special precautions are not exercised or required to protect tape files. U. S. N. Air Test Center Outstanding feature is the index register, decimal number system, capability of expansion of features, and floating and fixed point arithmetic. Tape is used largely for storing programs and intermediate results of computation. Small quantities of tape are required. Tapes which will in the near future be prepared from automatic data gathering systems will be property of other groups and storage of tape reels will not be required. USAF WADe System is used for conversion of specialized tape inputs, for editing volume data and for computation as required by presentation form; converSion, editing and computation in one system. Magnetic tapes are stored under temperature and humidity control, and are labeled and stored in a steel cabinet. Anna Magnetic tapes are identified by "stick-on" labels, stored in plastic containers, which in turn are stored in metal tape cabinets. Convair Outstanding features are alphabetic input via punched card converter; time clock (prints run time on paper tape); B + n modification (permits increasing index register by any number); and Bl ~4 and change control (makes the 4000 loop in memory as usable as the 7000 loops). A second paper tape reader BURROUGHS 204 has been installed to monitor computer operation during unattended operation. Tape handling: Plastic cases for each reel of tape are used. The reels are then stored in a steel cabinet. The cabinet is in the computer room which is temperature and humidity controlled. Socony - Dallas Outstanding features are versatile input-output :3ystems, an extensive command structure, on line curve output, F.M. analog magnetic tape output, and added commands. United Gas Unique system advantages are addressable magnetic tape blocks; modified logic to allow incrementing and decrementing of index register by integers in the range: 001 < integer < 1000; modified photoreader logic to allow input from special magnetic tape reader; and modified Model 500 Punched Card Converter to permit 120 alphanumeric characters per line on IBM 407.

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.

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: (l) 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. Tqe 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 sen- BURROUGHS 205 l30 sitive 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 l75 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 l.ocalized 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 1/176th of the basic monthly 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 components 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 included in a given program will not have use time accumulated 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 purchased 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 88/60.. Plan for Rental of Burroughs 205 Data ProceSSing Systems The reduced rental charges applic able 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 88/60 rental plan to the normal one hundred and seventy-six hour rental plan. When this conversion is made the customer may not revert to 88/60. Use of the system for more than one hundred and twenty-eight hours per month would make it advantageous for hint to convert. Burroughs will provide the necessary parts and service to maintain the equipment in good operating condition as required during its regular business BURROUGHS 205 136 hours, eight a.m. to five p.m., Monday through Friday excluding holidays. Burroughs 205 Data ProceSSing System may be of any configuration, the 88/60 plan applies only to on-line equipment. The tape perforaterand verifier model 454, the numeric code converter model 460, and other similar 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 88/60 is limited to twentyhours 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 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 was inoperative. Such credit shall be 1/176th of the monthly Charge for the inoperative machine plus 1/176th 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 1/3Oth 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. Lessee shall not be responsible for loss or damage to the equipment caused by fire, lightning, sprinkler leakage, tornado and wind storm, hail, water damage, explosion, smoke and smudge, aircraft and motor vehicle damage, earthquake, collapse of buildings or structures and strikes, riots or civil commotion. Burroughs Corporation shall provide transit insurance and comprehensive public liability insurance on the equlpment. Burroughs Corporation will furnish prescribed training of customer employees in programming and operating procedures and techniques. Additional services of a staff of qualified programmers, mathematical analysts and engineers to further improve specific utilization of the equipment may be contracted for.
