Honeywell Computer Model 290 MANUFACTURER Minneapolis-Honeywell Regulator Company Special Systems Division
Photo Photo by Minneapolis-Honeywell Regulator Company APPLICATIONS The Honeywell 290 Computer is a general purpose, internally stored program digital computer especially designed for use as a highly reliable on-line comput- er for process or operation monitoring and-or control. The H290 features all solid state circuitry, high speed, low clock rate, both core and drum memory, con- current input, output and compute operation. The H290 can be furnished with over 70 instructions selectable by the user from a list of over 150 avail- able instructions. The H290 Computer with associated peripheral equipment can accept over 4,000 inputs at scanning speeds up to 1,000 points per second, perform calculations in real-time and produce over 4,000 outputs.

A group of 80 micro-instructions are assembled into macro macro-instructions dependent upon the Control Section logic. These macro- instructions may be changed with comparative ease. A Control Section will be supplied according to the application and the user's desires and it can be modified or changed if the need arises. Assembly routines are provided. The H290 utilizes over 26 registers. Three are for inputs, 5 for outputs, 1 for instruction sequence, 4 for arithmetic and the balance for other internal computer functions. The entire core memory could be utilized as index registers. The basic operation code consists of 6 bits, 64 orders involving memory addresses. A "no-address" type of order allows for 64 additional orders not involving variable addresses. If additional orders involving memory are required, the Control Section may be easily modified to utilize a "no-address" order as one addressing memory. The Control Section by being mostly magnetic, can have its entire order structure completely altered if desired. Because it is not conceivable that any one application would have need of the complete possible instruction vocabulary, it can be said that the number of available instructions is limitless for a particular application.

Arithmetic mode Parallel 2's complement arithmetic is used throughout which allows a powerful but comparatively simple add net work. No special logic is needed to handle sign determination. Arithmetic is completely binary with a relatively simple decimal translator for addition and subtraction. Binary-to-Decimal and Decimal-to- Binary conversion orders are provided for complete flexibility. Timing Synchronous and Asynchronous The basic clock frequency of 50 kc is realized through use of an asynchronous logical clock of six unique time periods each of which is independently variable. Operation Sequential and Concurrent Instructions are executed in sequence but input, output and internal computations are easily realized simultaneously. The computer itself is synchronized by the clock, but the clock is not an oscillator or multivibrator. A basic timing device and logic manipulator have been combined into the Primary Clock which can have no false moves. Separate Core Memory and Drum Memory Clocks are synchronized by the Primary Clock.

Punched Paper Tape Up to 60 char/sec For subsequent feed to electric typewriters On-line Digital Up to 10,000 18 bit char/sec Two paths for selection of Input and Output Channels. By means of a unique order structure and proper programming, it is possible to interlace an input program, an output program and a computation program. The input program will initiate input commands to peripheral devices and then switch control to the computation program. The computation program will periodically check to see if the input device has completed its conversion. When complete, the input program may then call for the next input and then jump to the output program. An output command may then initiate action by an appropriate output device and then jump to the computation program. This may be considered as a form of "traffic control". Proper programming prevents a series of input and output commands from "backing up" and virtually eliminates any waiting time for peripheral devices. The order structure enables the checking of peripheral. devices for the completion of their last task and upon completion another command is issued to the peripheral device and the program can then immediately branch to another routine, periodically checking for the completion of the latest command issued to the peripheral device. The manner in which this is achieved by the program is quite simplified and flexible. Input and output channels are selectable by the twelve address bits of the input or output instruction thereby enabling the selection of any one of 4,096 inputs or 4,096 outputs.

Programmed system self checks and input and output reasonableness checks can be easily incorporated into the complete program. Particular types of checking can be incorporated in the order structure as a part of the Control Section on spec ial order at additional cost. Simple program checks and verifying diagnostic routines can easily be incorporated in the complete program.

PRODUCTION RECORD Time required for delivery from receipt of order 12 to 18 months. COST, PRICE AND RENTAL RATES For 1 Honeywell 290 Computer with 4,096 words of core memory and 8,192 words of drum memory, 1 Paper Tape Reader, and 1 Paper Tape Punch, the selling price is approx. $170,000. Electric typewriters or printers, analog-to-digi- tal converter, digital-to-analog converter, multi- plexers, operator console(s), and control amplifiers are available. The selling price of total system, including additional equipment, varies, depending upon the application requirements. Various leasing and maintenance arrangements are available. PERSONNEL REQUIREMENTS Maintenance, programming and operator training are provided according to the purchaser's requirement. RELIABILITY, OPERATING EXPERIENCE, AND TIME AVAILABILITY The H290 Computer has been designed for maximum reliability and 100% availability for continuous operation. The "mean time between failures" is well over a thousand hours of continuous operation. Wire- wrap and ,jet soldering techniques have been used throughout. Individual package construction utilizes ladder type arrangement of components. The number of components per package greatly reduces the usual number of mechanical connections; and floating connections are used throughout. Circuit parameters have been derated better than 50%. Computer operation is such that complete protection is provided for the prevention of the stored program or constants from being inadvertently destroyed by the operator or an external disturbance. ADDITIONAL FEATURES AND REMARKS Outstanding features include high performance and speed, high reliability, protected program storage, flexible instruction vocabulary, use of both core and drum memory, and ease of programming and main- tenance. Single instructions can be provided for complex sub-routines without requiring more than one reference to memory. Unique system advantages include random selection of inputs and outputs in accordance with the program, concurrent input, output and compute operation, and up to 1,000 points per second input selection speed. The Honeywell Computer Control System utilizing the H290 Computer is applicable for all types of industrial, commercial and military process or operation monitoring and control. Complete appli- cation assistance can be provided extending from economical and technical feasibility study through installation and maintenance of the system. All process transmitters, transducers and peripheral equipment can be provided by HONEYWELL. Concurrent Operation Execution of internal computations, concurrent with operation of almost any number of peripheral devices (such as paper tape reader, a tape punch, a typewriter, an analog-to-digital converter, etc.) is possible due to the internal logic and random access core memory of the computer. This feature effectively permits the attention of the computer to be devoted to continuous process control of the particular process and to the calculation of pro- cess formulae. For instance, the computer program can randomly select an input channel. If this input channel rep- resents a process variable such as a temperature (read by a thermocouple), its value is usually in analog form (continuous signal) and must be convert- ed to digital form (discrete digits) for presenta- tion to the computer: Conversions of this sort are handled by the computer peripheral equipment; in this case, the analog-to-digital converter. While the computer peripheral equipment carries out this conversion, the computer itself is free to perform other operations. Between operations, the computer "looks at" its input registers to see if the con- version is completed. When the peripheral equip- ment has completed the requested conversion, the computer is signaled and will accept the digitized value. The same principle applies to all peripheral opera- tions. All of these can occur concurrently. Transistorized for Reliability The Honeywell 290 has solid state components throughout all electronic circuits and is designed to operate in an industrial environment with a min- imum of maintenance. Reliability is further assured not only by the low clock rate but also by operating the transistors and diodes far below the maximum levels recommended by the component manufacturers. This lengthens component life. In addition, the Honeywell 290 contains a cooling unit to substanti- ally lower the internal temperature in the computer proper to further increase component life.

Diagram by Minneapolis-Honeywell Regulator Company Instruction and information word format Word Structure - The Honeywell 800 word consists of 54 bits, of which six are used for checking. The 48 information bits may represent an 11-decimal digit number with its sign, several smaller decimal numbers, with signs for each, eight alphabetic characters, or a combination of these. A word may also be interpreted as a 44-bit binary number with its sign, or as an instruction. Using the floating-point option, a word may represent a sign bit, a seven bit exponent, and a 40-bit mantissa in binary form. HONEYWELL 800 WORD STRUCTURE Instructions - In the instruction word, the information bits are divided logically into four sections which are interpreted as an operation code followed by three addresses. Instruction Word +--------------+------------+-----------+-----------+ | Operation | Address | Address | Address | | Code | A | B | C | +--------------+------------+-----------+-----------+ | 12 bits | 12 bits | 12 bits | 12 bits | +--------------+------------+-----------+-----------+ Indexing - Each address in an instruction may be designated as absolute or indexed. A total of eight index registers are available to each program. Masking - The ability to mask words allows most internal processing instructions in the Honeywell 800 to work with fields of variable length. Each program may designate a group of 32 memory locations as masking registers. Such a designation may be changed by the programmer at say point in his program. Thus, an essentially unlimited number of masking registers is at his disposal.
