About Adams Associates . . ,

Though well known as the publisher of the Computer Characteristics Quarterly, Adams Associates is more widely recognized as one of the country's leading computer consulting and programming firms. While the services offered by Adams Associates extend to all areas of computer technology, its reputation stems primarily from outstanding accomplishments in a number of specialized fields, including:

Since its inception in 1959, Adams Associates has steadily grown to the point where its technical staff now consists of almost seventy computer analysts and programmers with unusual qualifications and diversified backgrounds. In recent years the interests and capabilities of its staff and the needs of its clients have led to increasing emphasis by the firm on the development and implementation of advanced techniques for on-line time-shared computing and graphic man-machine interaction.

Being pioneers as well as specialists in these fields, Adams Associates long recognized the need for an authoritative and comprehensive source of information on and analysis of all graphic display hardware, software, applications and trends. It answered this need by applying its extensive knowledge and broad experience to the publication, in July 1966, of The Computer Display Review. Though still in its first year, the Review, which is updated every four months, has already become a highly regarded and widely used reference on the subject of alphanumeric, line-drawing and related displays.

What's new . , . ?

Much of what's new in this issue of the Computer Characteristics Quarterly is already apparent- its new cover and size, its increased coverage of the salient features of central processors, all of which now appear in one section and are listed alphabetically by country and manufacturer; its expansion of the characteristics of peripheral devices and their inclusion in a separate section, its addition of charts and tables designed to provide comparative and useful information of various kinds.

What is not so apparent is that twenty-eight new central processors have been added to Section I. These include the introduction of Business Information Technology, Inc. and its 480, and Standard Computer Corporation and its IC 6000 series. The other additions are the Digital Equipment PDP-10, EAI 640, Honeywell DDP-416 and DDP-516, Hughes H3118M, Scientific Control 6700, Scientific Data SIGMA 5, SEL 840 MP, Westinghouse PRODAC 250, EELM 4/75, Bull GE GAMMA 55 and GAMMA 145 (formerly GAMMA 141), CAE 90/10, 90/40, 90/80 and 10070, Siemens 302, 304 and 305, Telefunken TR86, Fujitsu FACOM 230/10, 20, 30 and 50, Nippon Electric NEAC 2200/50, Toshiba TOSBAC 7000/60, and Philips PR 8000.

Forty-six computers have been deleted from this issue because they are no longer being marketed and the number of them still in operation is insignificant. These computers will appear, with others deleted in the past, in the Annual Supplement to the Quarterly.

Received too late for inclusion herein were announcements of the InterData Model 3, Hewlett Packard HP-2116A and Control Data 3150. Their characteristics will be reported, of course, in the next issue of the Quarterly.

Central Processors

EXPLANATION OF COLUMN HEADINGS

Price Range
Monthly in Thousand Dollars
The range of monthly rental prices from the minimum useful configuration to the maximum practical configuration.
First Delivery
Month and Year
When the first operating installation was or is expected to be made.
Processor Speed
Complete Add Time in Microseconds
The time required to acquire from memory and execute one fixed-point add instruction using all features such as overlapped memory banks, instruction look-ahead and parallel execution. The add is either from one full word in memory to a register, or from memory to memory; but not from register to register. For non-core-type machines, maximum optimization has been assumed.
Storage Cycle Time in Microseconds For core storage, the total time to read and restore one storage word. For drum or other serial storage, the total time for one revolution.
Accumulators The number of directly-accessible general-purpose arithmetic registers available.
Internal Storage
The primary memory of the computer from which instructions can be directly executed and data accessed by the central processor. Memory is assumed to be core unless otherwise stated.
Capacity in Thousand Words The number of words of addressable internal storage available.
Word Size The number and type of digits c-cnnprising one storage word (A-alphanumeric, six, seven or eight binary digits; D - decimal, four binary digits: B - binary, one binary digit).
Floating-Point Precision The maximum number of binary digits used as the mantissa of a single-precision floating-point fraction.
Overlap The number of available independent memory busses which can be simultaneously used to access memory from the central processor.
Instruction Set
Address Size
The maximum number of binary digits in an instruction used in directly addressing memory.
Operation Codes The number of internal machine instructions available.
Indirect Addressing The availability and level of indirect addressing (1 - single level, oo - unlimited).
Index Registers The maximum number of special registers whose contents may be added to the address portion of an instruction to form an effective instruction address.
Extensiveness The availability, as either standard or optional features, of byte manipulation, double precision, translate-edit capability, floating-point instructions, hardware multiply-divide, or logical operations.
Time-Sharing The availability of hardware features primarily for, or useful to, time-shared operation.
Base Address Relocation The ability to augment memory references by the contents of a specific base register, alterable only in the supervisor mode.
Clock A special-purpose addressable register automatically increased or decreased by one unit at a fixed rate.
Program Interrupt A special feature which, on the occurrence or completion of an internal or external operation, can be used to initiate a new program sequence.
Memory Protection The ability to prevent, under program control, portions of memory from being used by programs or input-output operations.
Dynamic Page Relocation The segmentation of internal storage into blocks whose addressing is automatically controlled by a memory-protected set of addressable registers.
Supervisor Mode A mode of operation only under which certain operations, such as memory-protection modification instructions and input-output operations, are permitted.
Input-Output Channels
Number
The number of individual buffered input-output channels available.
Transfer Rate The maximum transfer rate in characters per second.
Auxiliary Storage
External mass storage devices, whether fixed or movable head, other than magnetic tape marketed by the central processor manufacturer. The manufacturer's model numbers for available devices are given.
Magnetic Tape
Available tape units marketed by the central processor manufacturer listed by the manufacturer's model number.
Peripheral Devices
Available peripheral devices marketed by the central processor manufacturer, listed by type (card reader, card punch, printer, paper-tape reader, paper-tape punch), using the manufacturer's model numbers.
Software
Algebraic Compiler
Assumed to be FORTRAN IV and available now or when the first computer is delivered, unless otherwise noted.
Monitor The manufacturer-supplied executive or supervisory systems available now or when the first computer is delivered, unless otherwise noted.
Business Compiler Assumed to be COBOL and available now or when the first computer is delivered, unless otherwise noted.
