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.

There is no need for "built-in" subroutines. 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.

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.

CHECKING FEATURES
Due to the nature of the applications on which this
computer is intended to be used there is no requirement for
parity checks nor checking bits associated with any word.
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.

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.

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.
