			RT PC HARDWARE DETAILS

RYE BROOK, NY, January 21 . . . The line of high-speed, 32-bit personal
workstations announced by IBM today is the company's first to perform
standalone processing of Computer-Aided Design/Computer-Aided Manufacturing
(CAD/CAM) and Computer-Aided Engineering (CAE) tasks such as airplane,
ship, automobile and circuit design.

The IBM RT Personal Computers, designed for technical professionals, 
scientists and engineers in industry, academia and government, use a new
IBM operating system -- Advanced Interactive Executive (AIX - TM).  The
new system combines the multi-user, multitasking features of UN*X with
IBM-developed ease-of-use enhancements, an optional relational data base
and one trillion bytes of virtual memory.  

The RT PCs are the company's first workstations to contain
IBM-invented Reduced Instruction Set Computer (RISC) architecture.
This architecture is used on a new, IBM-developed 32-bit
microprocessor chip to speed processing.

Among the computers' features are application program interfaces that allow
others to develop software and hardware applications and an optional $995
PC AT coprocessor card.  The card, along with a new $550 coprocessor
program, permits many PC DOS programs to run, without modification, 
concurrently with RT PC programs and to share RT PC disk files and displays.
In addition, IBM announced nine application programs for RT PCs, 
including IBM's first integrated circuit design program.

Floor-standing RT PCs can be configured as host processors for the
IBM 5080 graphics system, to permit -- for the first time --
standalone Computer-Graphics Augmented Design and Manufacturing
(CADAM - TM) processing without attaching a 5080 to a large IBM host
computer.  In this configuration, 5080s can be connected concurrently
to RT PCs and host computers, and users can switch between RT PC and
host programs simply by pressing several keys on the keyboard.

IBM also enhanced its 5080 graphics system today with two powerful and less
expensive models of the IBM 5085 graphics processor, models 2 and 1a.  

The new RT PC line consists of:

--	IBM RT PC 6151 Model 10, a desktop unit, similar in size to IBM
	Personal Computers, that comes with one megabyte (MB) of real
	memory, expandable to 3MB, and 40Mb of fixed-disk capacity.  A
	101-key, adjustable-tilt keyboard, which can be used for many
	applications including numerical data analysis, graphics and text,
	is also standard with the model 10.

--	IBM RC PC 6150 models 20, 25, and A25, floor-standing units that
	fit under a desk and can be used either as standalone computers or
	host processors for an attached 5080 graphics system.  Model 20
	comes with 1MB of real memory, expandable to 3MB, and 40Mb of fixed-
	disk storage, expandable to 180MB.  Models 25 and A25 come with 2MB 
	of real memory, expandable to 4MB, and 70Mb of fixed-disk storage
	expandable to 210MB.  Models 20 and 25 come with the 101-key
	keyboard and, when attached to the 5080 graphics system, use the
	5080 keyboard.  Model A25, designed for use only with the 5080
	system and keyboard, comes without the 101-key keyboard.

Optional products also announced to day for all RT PCs are:

--	A choice of three new, all-points-addressable graphics displays.
	The IBM 6153 advanced monochrome graphics display is a 12-inch unit
	with 720 by 512 picture elements (pels).  The IBM 6154 advanced
	color graphics display is a 14-inch unit with 720 by 512 pels
	and can display 16 colors simultaneously.  The IBM 6155 extended
	monochrome graphics display is a 15-inch unit with 1024 by 768 pels.
	RT PCs also can use the current IBM 5151 PC display and IBM 5154 PC
	enhanced color display.

--	The IBM 6157 streaming tape drive, a backup storage device that
	provides users of RT PCs  and the IBM System/36 with a fast,
	convenient way of saving, transferring and restoring information.
	The new unit stores up to 55Mb of data on 1/4-inch tape at data
	rates up to 5MB per minute.

--	The eight-pen, IBM 6180 color plotter, designed to produce
	high-resolution engineering drawings, graphs, charts and diagrams
	on standard-sized transparencies and paper.  This desktop unit also 
	attaches to most IBM PCs and the 5080 graphics system.

Optional new product for all  RT PCs and the 5080 graphics system are:

--	The IBM 5083 tablet model 12 that permits CAD/CAM designs to be
	modified quickly, providing very precise movement of the
	scren cursor in any direction.  This tablet, which replaces the 
	model 1, is priced at $575, 11.5 percent less than its predecessor.

--	A compact, lighted program function, 32-keyboard.  Keys that are
	operable during program sessions light up so users know which
	keys to press.  The entire bottom of each operable key is lit so
	users can view keys more easily.

				RT PC DETAILS

All models come with one 5-1/4 inch fixed-disk drive and one high-capacity
1.2Mb diskette drive.  Diskette storage in models 20, 25 and A25 is expandable
up to 2.4 MB.  For those users of floor-standing models who do not expand to 
the full 2.4 MB diskette capacity, an optional 360Kb diskette drive is
available to enable RT PC diskettes with PC DOS programs to be used on
PCs and PC XTs.

All RT PCs are equipped with a PC AT-compatible, 16-bit input/output bus,
which allows users to attach a wide variety of IBM and non-IBM personal
computer peripheral devices -- printers, displays, disk storage units,
plotters and communications adaptors. To enable the devices to attach, the 
RT PC desktop unit has six feature slots and the floor-standing models
have eight.

An input/output bus is an electrical connection through which data is 
transferred between the processing unit and input/output devices.  A
separate 32-bit data bus is dedicated to transferring data amond the
microprocessor, virtual memory management unit and an optional floating-
point accelerator card.

This card, offered with all RT PC models, attaches to a special, dedicated
slot on the RT PC system board and processes floating-point instructions.
These instructions also can be processed in the PC AT coprocessor with an
optional math coprocessor chip.

RT PCs can communicate with IBM host computers through an optional RT PC
3278/79 data communication adaptor or with IBM and non-IBM host computers
to be transferred to and manipulated on RT PCs, thereby freeing host 
computers for other tasks.

An optional IBM PC Network adaptor card that connects RT PCs to an IBM
PC Network also is available with all new RT PC models.

A diagnostic package specially designed for RT PCs analyzes hardware failure
information.  The package, included with the workstsations, enables RT PC 
operators to help determine which IBM element -- system unit, display or
keyboard -- needs service.

   DESCRIPTION
          The RT Personal Computer System is an advanced computer
   designed for the technical professional, for increased personal
   productivity, as well as for technical applications in engineering,
   science, and CAD/CAM.  It includes technology not previously
   available in IBM Personal Computers: an IBM-developed,
   high-performance, 32-bit microprocessor and 40-bit virtual memory
   management unit, floating-point, high capacity fixed-disk drives,
   large system memory, and an optional IBM Personal Computer AT
   Coprocessor. The optional features and attachable devices supported
   include both newly developed products as well as many existing IBM
   Personal Computer products.
          The multi-tasking, multi-user system is managed by the IBM RT
   Personal Computer Advanced Interactive Executive (AIX(TM)) Operating
   System, derived from UNIX(1) System V(2) but with significant
   IBM-developed enhancements: virtual machine support and hardware
   assisted virtual system management, file system improvements,
   floating-point support, data management, support for high-resolution,
   all-points addressable (APA) displays, installation/configuration
   support, and an interface designed for ease-of-use.
          The RT Personal Computer model 020, 025, or A25 can be
   attached to an IBM 5080 Graphics System to provide a compact, modular
   graphics system that can support computer-aided design capabilities
   on the IBM 5080 Graphics System while retaining an independent but
   integrated relationship with larger hosts.  (Model A25 is a model 025
   with an IBM RT Personal Computer 5080 Attachment Adapter [#7860] and
   without a keyboard. A keyboard is not required when attached to a
   5080.)  Additional details of this configuration are given in IBM
   Product Announcement 186-009, dated January 21, 1986.
   (1UNIX is a Trademark of AT&T Bell Laboratories
   (2The AIX Operating System is based on INTERACTIVE Systems
     Corporation's IN/ix*, which is based, in turn, on UNIX System V, as
     licensed by AT&T Bell Laboratories.  Portions of the modifications
     and enhancements were developed by IBM and portions were developed
     by INTERACTIVE under contract to IBM.
   * Registered trademark of INTERACTIVE Systems Corporation.
   TECHNOLOGY
          The system processor has a 32-bit, reduced instruction set
   computer architecture, developed by IBM on a single chip using
   2-micron FET technology. It has sixteen 32-bit general purpose
   registers and uses 32-bit addresses and data paths.  The
   microprocessor is controlled by 118 simple 2-and 4-byte instructions.
   An IBM-developed advanced memory management chip provides virtual
   memory address translation functions and memory control. It provides
   a 40-bit (1 terabyte) virtual address.
          The reduced instruction set computer architecture provides a
   system which is oriented toward pervasive use of high-level language
   programming, while providing a storage and I/O organization to enable
   the central processing unit to execute most register-to-register
   instructions in a single cycle.
   PERFORMANCE
          The IBM RT Personal Computer microprocessor has a cycle time
   of 170 nanoseconds and typically executes at 1.6 to 2.1 million
   instructions per second (MIPS), depending upon the actual instruction
   mix.  It should be noted, however, that actual system throughput is
   dependent on numerous other factors.  For central processing unit
   intensive tasks, the RT Personal Computer has approximately two times
   the execution speed of an IBM Personal Computer AT model 099.  The RT
   Personal Computer has a 4-byte wide memory interface with 8-bits of
   error correcting code (ECC), which provides a bandwidth of 23.5
   Mb/second.  The I/O bus bandwidth is 2 to 4 Mb/second.
          The optional Floating-Point Accelerator increases the IBM RT
   Personal Computer's capability to process floating-point operations
   and has an approximate performance up to 200 thousand Whetstone
   instructions per second (KWIPS) when supported by the AIX Operating
   System (5669-061) (#5034).  The Floating-Point Accelerator normally
   operates in virtual mode and provides support for the format and
   basic operations defined by the ANSI/IEEE 754-1985 Binary
   Floating-Point Standard. The additional operations in the standard
   are supported when the AIX Operating System is used in conjunction
   with the Floating-Point Accelerator.
          When used in conjunction with Personal Computer AT Coprocessor
   Services (5669-059) (#5030) and a dedicated Personal Computer display
   (IBM 5151 or IBM 5154) which is recommended for improved performance,
   the IBM Personal Computer AT Coprocessor option provides the
   capability to run many IBM Personal Computer AT programs concurrently
   with and under the control of the IBM RT Personal Computer main
   processor using only the system memory.  Performance will be less
   than that of the Personal Computer AT.  In general, the Coprocessor
   will operate with performance better than the IBM Personal Computer
   XT when memory is shared with the RT Personal Computer main
   processor. The performance can be improved substantially (up to twice
   the PC XT performance in processor-intensive or disk-intensive tasks)
   if the dedicated IBM Personal Computer AT 512Kb Memory Expansion
   Option (#0203) is installed.
   CONFIGURATION
          The 6150 models 020 and 025 workstations and the 6151 model
   010 workstation with their associated options and attachments form
   the hardware base. They offer the capability to configure stand-alone
   and clustered workstations.
          The 6150 model A25 serves as a private host executing the
   graphics application for a 5080 Graphics System workstation via a
   serial link adapter which is standard with this model.  An
   appropriately configured model 020 or 025 can also be equipped for
   use in this configuration by addition of a 5080 Attachment Adapter
   (#7860).  (Consult specific application requirements for recommended
   configuration of fixed-disk and memory.)
          All models of the RT Personal Computer are based upon the
   high-performance, IBM-developed, 32-bit microprocessor and 40-bit
   virtual memory management card.  The processor operates at a
   170-nanosecond cycle time. Two-way memory interleaving results in
   overlapped memory accesses, providing the equivalent of a
   170-nanosecond memory cycle.  All models provide full 32-bit
   processing and 40-bit virtual addressing capability.  The I/O bus
   provides a path for 16 data bits with 24-bit addressing.
          All models of the RT Personal Computer are equipped with a
   high capacity (1.2Mb) diskette drive and an integrated date/time
   clock with battery backup.  Models 010, 020, and 025 are also
   provided with a keyboard with a layout that is similar to the IBM
   3161 ASCII Display Station, and attached cable.  Standard memory on
   the models 010 and 020 is 1Mb and on the model 025, standard memory
   is 2Mb. In addition, models 010 and 020 are equipped with a
   5-1/4-inch fixed-disk drive with a capacity of 40Mb of storage, while
   model 025 has a 5-1/4-inch fixed-disk drive with a capacity of 70Mb
   of storage.  Models 020 and 025 each have two standard asynchronous
   (RS-232C) serial ports with direct memory access in the base unit.
   These serial ports are recommended for attachment of high data rate
   devices such as the IBM 3812 Pageprinter.  Each model can be further
   expanded through customer setup options.  Memory can be expanded to
   4Mb via an optional 1Mb or 2Mb Memory card in the dedicated card
   slot.
          Additional direct-access storage is available for models 020
   and 025 only by adding up to two more fixed-disk drives, and a second
   high capacity diskette drive (1.2Mb) or IBM Personal Computer AT
   dual-sided diskette drive (320/360Kb).  These combinations result in
   a maximum fixed disk storage of 210Mb and with a maximum diskette
   storage of 2.4Mb.
          Fixed-disk backup for save/restore of recorded information is
   available through the optional IBM 6157 Streaming Tape Drive.  (See
   IBM Product Announcement 186-008, dated January 21, 1986.  The 6157
   tape cassettes also provide a medium for data interchange between
   systems.
          Models 020 and 025 are closely related to one another in that
   the same hardware options are available on each and the same software
   product offerings execute on each. All models are related to the
   existing Personal Computer product family through support of an
   optional IBM Personal Computer AT Coprocessor card and the associated
   software support, and utilization of the IBM Personal Computer AT
   bus.
          Model 010 has six feature slots and the models 020 and 025
   contain eight feature slots which support devices, features, or IBM
   Personal Computer AT memory.  Six of the slots (five in model 010)
   may be occupied by either RT Personal Computer or Personal Computer
   AT 16-bit option cards or by Personal Computer 8-bit option cards.
   Two slots (one in model 010) support 8-bit options only.  As shipped
   by IBM, all models use one of the 16-bit slots for the standard
   combination fixed-disk and diskette drive adapter.  In addition,
   there are two additional dedicated slots for system memory cards, one
   of which has the factory installed memory (1Mb for models 010 and 020
   and 2Mb for model 025).  There is also an additional dedicated slot
   for the optional Floating-Point Accelerator.
          All models also include a security keylock as standard, which,
   when locked by the user, can help to prevent removal of the RT
   Personal Computer cover, initialization of the system, and entry of
   commands or data from the keyboard.  A programmable speaker, which
   can be used to produce tones, is also provided in the keyboard.
          The keyboard is standard on the models 010, 020, and 025, and
   is attached to the RT Personal Computer via an attached 2.5-meter
   (8.2-foot) cable, permitting a variety of workspace configurations.
   The keyboard uses a keyboard layout similar to that recently
   announced with the IBM 3161 ASCII Display Station.  The keyboard,
   with 101 keys, a 30 mm height, and adjustable tilt, offers commonly
   used data and word processing functions along with separate
   typewriter and numeric keypads.  Cursor keys, arranged in an inverted
   "T" pattern, are independent of numeric keys.  Key-location
   enhancements and light-emitting diode (LED) mode indicators (cap
   lock, insert mode, scroll lock) improve keyboard usability.  Special
   symbols may be accessed with a combination of keys.
          In the case of the model A25, which is for use with the 5080
   Graphics System, the keyboard is provided with the 5080 rather than
   as a part of the 6150 Model A25.
   OPTIONAL FEATURES
   IBM RT PERSONAL COMPUTER FLOATING-POINT ACCELERATOR (#4758)
          The Floating-Point Accelerator plugs in to a special slot (not
   an I/O feature slot) on the RT Personal Computer system board.  It
   supports both single (32-bit) and double (64-bit) precision
   floating-point operations using 32 sets of 14 registers (32-bits
   each) provided in the Floating-Point Accelerator.  This option
   provides significant performance improvement for floating-point
   calculations.  It supports the format and basic operations defined by
   the ANSI/IEEE 754-1985 Binary Floating-Point Standard.  The IBM RT
   Personal Computer Advanced Interactive Executive Operating System
   (5699-061) (#5034) is required in order to support additional IEEE
   754 operations and exception handling.
   IBM RT PERSONAL COMPUTER 1MB MEMORY EXPANSION (#8222)
          One additional 1Mb memory expansion may be added to any model.
   This option increases the model 010 or 020 memory from 1Mb to 2Mb and
   the model 025 memory from 2Mb to 3Mb.
          Memory is divided into two "arrays" of 512Kb with interleaving
   to overlap memory access and achieve the equivalent of 170-nanosecond
   cycle time.  Four data bytes and one error correcting code (EEC) byte
   are transferred at a time over a 32-bit data path plus 8-bit ECC.
   IBM RT PERSONAL COMPUTER 2MB MEMORY EXPANSION (#4739)
          One additional 2Mb memory expansion may be added to any model.
   This option increases the model 010 or model 020 memory from 1Mb to
   3Mb, and the model 025 memory from 2Mb to 4Mb, and may also be used
   to upgrade the model 010 or model 020 memory to 4Mb (with complete
   replacement of the 1Mb memory that comes with the machine).
          Memory is divided into two "arrays" of 1Mb with interleaving
   to overlap memory access and achieve the equivalent of a
   170-nanosecond cycle time. Four data bytes and one ECC byte are
   transferred at a time over a 32-bit data path plus 8-bit ECC.
   ADDITIONAL FIXED-DISK STORAGE

   CONNECTION OF 6150 MODEL A25 TO THE 5080 GRAPHICS SYSTEM
          The 6150 model A25 System Unit may be connected to the 5080
   Graphics System through the use of appropriate features/prerequisites
   in the 5080 and/or 5088 (See IBM Product Announcement 186-009, dated
   January 21, 1986.  Connection of the 5080 system to the 6150 Model
   A25 allows the 5080 to operate in a stand-alone environment with the
   6150 as the Graphics Application Processor.  An appropriately
   configured 6150 model 020 System Unit/Keyboard or IBM 6150 model 025
   System Unit/Keyboard can also be upgraded with the RT Personal
   Computer 5080 Attachment Adapter, (#7860) to connect to the IBM 5080
   System.  (Consult specific application requirements for recommended
   configuration of fixed-disk and memory.)  The 5080 Attachment Adapter
   also allows the 5080 to be switched between stand-alone and
   System/370 mainframe interactive modes via the keyboard.  Mainframe
   interactive mode requires a 5088 Channel Control Unit as a part of
   the 5080 configuration.  (Note: The CAD/CAM application must reset
   the 5080 state, when switching between the host and the IBM RT
   Personal Computer.  The 5083 Tablet is supported only on the 5080
   until third quarter 1986, at which time RT Personal Computer support
   will also be available.  Support for keyboards other than U.S.
   English will be available only on the 5080 until third quarter 1986,
   at which time RT Personal Computer support will also be available.)
   The attachment is made via a 4.6-meter (15-foot) industry standard
   coaxial cable supplied with the adapters, and requires a 16-bit
   feature slot.  Customer supplied coaxial cable may also be used. (See
   Physical Planning Information).  If model 020 or 025 is already
   installed, order IBM RT Personal Computer 5080 Attachment Adapter
   (#7860) for installation in model 020 or 025, and appropriate
   features on IBM 5080 Graphics System (including #6150) to make
   connection.
   SECURITY, AUDITABILITY, AND CONTROL
          The RT Personal Computer can be used and managed so as to
   limit the risk of unintended modification, destruction, or disclosure
   of sensitive data.
          User management is responsible for evaluation, selection, and
   implementation of security features, for administrative procedures,
   and for appropriate controls in application systems.
          If sensitive data is sent over external communication
   facilities, user management may wish to pursue the application of
   cryptography.
   PLANNING INFORMATION
