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.

  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
(5669-061) (#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
       Fixed-disk storage on the model 020 or 025 may be expanded by
up to two additional fixed-disk drives (not available on the model
010).
       Space and power are provided in the system unit for up to
three fixed-disk drives.  The first two fixed-disk and diskette
drives use the standard combination fixed-disk and diskette drive
adapter in the system unit.  When a third fixed-disk drive is to be
added to an RT Personal Computer system unit, a Personal Computer AT
fixed-disk and diskette drive adapter and cable must be installed in
a 16-bit feature slot as a prerequisite.
       Either the 40Mb or 70Mb fixed disk-drives described below can
be added as the second and third drive for models 020 or 025.  Both
drives have the same physical size and both have a dedicated landing
zone for the read/write heads to protect the drive and its contents
during shipping, movement, or storage.

IBM PERSONAL COMPUTER AT FIXED-DISK AND DISKETTE DRIVE ADAPTER
(#3428): One of these adapters is included in all models of the RT
Personal Computer for attaching the first two fixed-disk drives and
two diskette drives on the models 020 and 025 (standard fixed disk
drive and diskette drive on model 010).  A second adapter is
available for attaching the third fixed-disk to the model 020 or
model 025.  The adapter supports the attachment of both the 40Mb and
70Mb fixed-disk drives and the high capacity diskette drive as well
as the dual-sided diskette drive.  Fixed-disk data rate is 5M bits
per second.  Diskette data rates are 250/300/500K bits per second.
The adapter requires a 16-bit feature slot and a Fixed-Disk Attach
Cable (#8541) when used as a second adapter.
IBM RT PERSONAL COMPUTER MOUSE (#8426): This mouse provides a
two-button mechanical device to provide positional input for screen
pointing and cursor movement on a display screen.  It includes a
2.5-meter (8.2-foot) cable and plugs into a specially keyed locator
port on the IBM RT Personal Computer system unit.  The adapter is
included in the standard system electronics so no additional adapter
is required.  A snap-lock cover opens easily for routine cleaning of
the rollerball. If the RT Personal Computer Mouse is attached to the
system, the IBM 5083 Tablet cannot also be concurrently attached,
since both attach through the locator port.
LIGHTED PROGRAM FUNCTION KEYBOARD (#4710): The lighted program
function keyboard is a separate assembly with 32 keytops in which a
bright indicator light is imbedded in each key top for easy viewing
from the side.  They are turned on and off under application control
to indicate which keys may be selected at a given moment.
Correspondingly, a unique signal is returned to the application for
any key pressed. In this way, a user may interact with an
application.  The device is supplied with a cable that plugs into the
RT Personal Computer 5080 Peripheral Adapter via a cable supplied
with the RT Personal Computer 5080 Peripheral Cable Kit (#7564),
giving a total cable length of 2.4 meters (7.9 feet).
DIALS (#8710): The dials unit is a flat, compact, low-profiled,
desk-top device with eight cone-like dials. The dials may be turned
continuously in either direction. Upon rotating the dials, a range of
scalar values indicating direction and extent of rotation are
signaled to the processor.  An application can read and interpret
this input for any suitable purpose, such as panning, zooming, and
rotating two- or three-dimensional images.  The device is supplied
with a cable that plugs into the RT Personal Computer 5080 Peripheral
Adapter via a cable supplied with the RT Personal Computer 5080
Peripheral Cable Kit (#7564), giving a total cable length of 2.6
meters (8.5 feet).
IBM RT PERSONAL COMPUTER AT COPROCESSOR CARD (#4756): This feature
provides for execution of many IBM Personal Computer and IBM Personal
Computer AT programs concurrent with and under control of the RT
Personal Computer 32-bit native processor.  With appropriate program
support (the IBM RT Personal Computer AT Coprocessor Services
licensed program (5669-059)), this feature enables IBM RT Personal
Computer workstations to emulate the IBM Personal Computer AT models
068 and 099.  Performance will be better than that of the IBM PC XT
(in general) but less than that of the IBM Personal Computer AT.
Performance can be improved substantially if the IBM Personal
Computer AT 512Kb Memory Expansion (#0203) is installed.  A dedicated
Personal Computer Display (IBM 5151 or IBM 5154) is also recommended
for improved performance.
       This Coprocessor option must be installed in a designated
16-bit feature slot. Only one can be installed on an IBM RT Personal
Computer system.
       An IBM Personal Computer AT Math Coprocessor (#0211) and IBM
Personal Computer AT 512Kb Memory Expansion Option (#0203) may be
used in combination with the IBM Personal Computer AT Coprocessor
Card.  The 512Kb Memory Expansion (#0203) is required for improved
performance if the system memory is less than 2Mb.
IBM PERSONAL COMPUTER AT MATH COPROCESSOR (#0211): The IBM Personal
Computer AT Math Coprocessor is a numeric processor extension with
floating-point, extended integer, and binary-coded decimal notation
(BCD) data types. When installed in combination with the IBM RT
Personal Computer AT Coprocessor Card (#4756), the Math Coprocessor
operation conforms to the Proposed IEEE Binary Floating-Point
Standard (Version 8.0).  The Math Coprocessor is installed in a
socket on the IBM RT Personal Computer/Personal Computer AT
Coprocessor Card (#4756).  The Personal Computer AT Coprocessor Card
(#4756) is a prerequisite for the IBM Personal Computer AT Math
Coprocessor.  Only one Math Coprocessor can be installed on an IBM RT
Personal Computer system.
IBM PERSONAL COMPUTER AT 512KB MEMORY EXPANSION (#0203): This allows
for the addition of 512Kb memory on the I/O bus.  When this memory is
used in combination with the IBM RT Personal Computer/Personal
Computer AT Coprocessor (#4756), the Coprocessor programs execute
substantially faster.  This feature is plugged into a 16-bit feature
slot on an IBM RT Personal Computer, and is required for optimal
Coprocessor performance if the system memory is less than 2Mb.
       The performance characteristics of this memory expansion are
the same as for other IBM Personal Computer AT user memory.  Parity
per byte and a 16-bit data path are supported.  This memory can be
accessed by the Coprocessor and/or the IBM RT Personal Computer
system processor, but is intended for performance enhancement of the

Coprocessor.  A maximum of two 512Kb memory expansion features may be
installed.  Coprocessor memory addressing may be limited by the
various operating systems and/or application programs used with the
Coprocessor.
IBM PERSONAL COMPUTER AT SERIAL/PARALLEL ADAPTER (#0215): This
adapter provides a serial port and a parallel port.  This card
occupies one feature slot of either type (8-bit or 16-bit).  The
serial portion is fully programmable and supports asynchronous
communications from 50 to 9,600 bits per second.  It offers the same
subset of the EIA RS-232C interface which is provided by the IBM PC
Asynchronous Communications Adapter card but on a nine-pin external
connector.
       The parallel portion of the adapter provides the ability to
attach various devices such as printers that accept eight bits of
parallel data, and provides the equivalent interface to the IBM
Personal Computer Printer Adapter card.  One or two IBM Personal
Computer AT Serial/Parallel Adapters may be installed in any model.
(However, only one parallel port may be used if the IBM Monochrome
Display and Printer Adapter, (#4900) is also installed.)
IBM RT PERSONAL COMPUTER STREAMING TAPE DRIVE ADAPTER (#4797): This
option provides a quarter-inch cartridge (QIC-02) tape interface to
the IBM RT Personal Computer.  It supports attachment of the IBM 6157
Streaming Tape Drive (6298184), which provides for data interchange
capability between all models of the IBM RT Personal Computer as well
as for fixed-disk backup and restore at rates up to 5Mb/minute in
image dump mode.  The card requires a 16-bit slot on the IBM RT
Personal Computer.  System Unit, and provides a 37-pin 'D' shell male
external connector. Only one adapter can be installed on an IBM RT
Personal Computer System.
IBM PERSONAL COMPUTER 3278/79 EMULATION ADAPTER (#2507): This adapter
provides a coaxial connection between an RT Personal Computer and
3274 Display Control Unit (in CUT mode only), or between a Personal
Computer and the integrated display/printer adapter of either the
4331 Processor or the 4361 Processor.  This adapter provides the
'handshaking' between the two units.  The RT Personal Computer
3278/79 Emulation licensed program running under the RT Personal
Computer Advanced Interactive Executive (AIX) Operating System
(55X8994) is also required for support of the connection. The DCA
protocol is supported.  A maximum of one adapter per RT Personal
Computer system is supported.  Customer-supplied cabling is required.
Host programming is required for host interactive applications.
IBM RT PERSONAL COMPUTER FOUR-PORT ASYNCHRONOUS RS-232C ADAPTER
(#4763): This provides a subset of the EIA RS-232C interface signals
on each of four 10-pin connectors for the independent attachment of
ASCII terminals, asynchronous modems, or serial devices like plotters
and printers (supports attachment of 3812 Pageprinter and/or the 4201
Proprinter with serial attachment #3000).  Maximum data rate
supported is 19.2Kbps over a 50-foot distance.  This adapter may
coexist in an RT Personal Computer with the RT PC Four-Port
Asynchronous RS-422A Adapter (#4764) and the IBM RT PC 5080
Peripheral Adapter (#7561). A maximum of four of these adapters may
be installed in the models 020 and 025 (maximum of three in model
010).  Each adapter requires an available 16-bit feature slot.
IBM RT PERSONAL COMPUTER FOUR-PORT ASYNCHRONOUS RS-422A ADAPTER
(#4764): This provides a serial interface of EIA RS-422A signals on
each of four 6-pin connectors for the independent attachment of ASCII
terminals.  Maximum data rate supported is 19.2Kbps over a distance
up to 4,000 feet. (User-supplied surge suppressor required if
distance is greater than 400 feet).  The interface cable should not
be installed outdoors.  This adapter may coexist in an RT Personal
Computer with the Four-Port Asynchronous RS-232C Adapter (#4763) and
the RT Personal Computer 5080 Peripheral Adapter (#7561).  A maximum
of four of these adapters may be installed in models 020 and 025
(maximum of three in model 010).  Each adapter requires an available
16-bit slot.
IBM PERSONAL COMPUTER NETWORK ADAPTER (#0213): The PC Network Adapter
is an option for connecting the RT Personal Computer to an IBM PC
Network with IBM Personal Computers, IBM Personal Computer XTs, IBM
Portable Personal Computers, or IBM Personal Computer ATs.  Each RT
Personal Computer requires one IBM PC Network Adapter card, which is
supplied with a three-meter attachment cable.  This cable can be
connected directly to the PC Network and its associated translators,
expanders, and cable kits.  Customer-supplied software is required
for proper utilization.  Data may be sent to the PC Network Adapter
from the RT Personal Computer via programmed I/O operations and
received from it both via programmed I/O operations and direct memory
access.
IBM RT PERSONAL COMPUTER 5080 PERIPHERAL ADAPTER (#7561): This
provides for the attachment of the Lighted Program Function Keys
(#4710) and the Dials (#8710).  This adapter is not required if the
RT Personal Computer is to be connected to a 5080 Graphics System.
In that case, the lighted program function keyboard and dials are
connected to the IBM 5085 Graphics Processing Unit.  This optional
three-port card plugs into a 16-bit feature slot on the RT Personal
Computer.  The ports provide an RS-232C subset (XON/XOFF protocol
only) as well as DC power to the attached devices.  Modem control
lines have been preconditioned on the adapter so that a plotter may
be attached to any port using the XON/XOFF pacing protocol and the
same printer/plotter cable used for attachment to the Four-Port
Asynchronous RS-232C Adapter.  Only one 5080 peripheral adapter is
supported per IBM RT PC System Unit, and the total of this adapter
and any four-port adapters installed on the RT Personal Computer may
not exceed four per system (three per model 010). One RT Personal
Computer 5080 Peripherals Adapter Cable Kit (#7564) is required for
each 5080 peripheral to be attached.
IBM RT PERSONAL COMPUTER 5080 ATTACHMENT ADAPTER (#7860): This
consists of an adapter card and a cable kit.  The adapter card plugs
into a 16-bit feature slot in an appropriately configured RT Personal
Computer model 020 or 025 and enables these models to connect to the
5080 Graphics System like the model A25.  (This feature card is
standard with model A25.  Consult specific application requirements
for recommended configuration of fixed-disk and memory.)  Connection
of the 5080 Graphics System workstation to the 6150 allows the 5080
to operate in a stand-alone environment with the 6150 as a private
host.  It allows the 5080 to be switched between stand-alone and
System/370 mainframe interactive modes via the keyboard.  (Note:
Mainframe interactive mode requires a 5088 Channel Control Unit as a
part of the 5080 configuration.  The CAD/CAM Application must reset
the IBM 5080 state, when switching between the mainframe and the IBM
6150.)  Mainframe interaction provides the 5080 with access to
System/370 applications.  The attachment of the RT Personal Computer
to the 5080 is made via a 4.6-meter (15-foot) industry standard
coaxial cable supplied with the adapter and requires a  16-bit I/O
slot.  Customer supplied coaxial cable may also be used. See IBM RT
Personal Computer Site Planning and Preparation Guide (GA23-1058).
Transfer speed of information between the 6150 and the 5080 can be up
to 2Mbits/sec.  The 5080 Attachment Adapter includes the attachment
card, a 15-foot coaxial cable for connection of the 5080 and RT
Personal Computer, a 15-foot 'Y' cable for switching the keyboard and
tablet between the 5080 or RT Personal Computer, required microcode,
and supporting publications.  (Note:  The 5083 Tablet is supported
only on the 5080 until third quarter 1986, at which time IBM RT
Personal Computer support will be available.  Support for keyboards
other than U.S. English will not be available on the RT Personal
Computer until third quarter 1986.)  See IBM Product Announcement
186-009, dated January 21, 1986 announcing corequisite features
required on the IBM 5088 and IBM 5085 and recommended hardware and
software configurations.

       The Extended Monochrome Graphics Display Adapter features a
1,024 x 1,024 bit map on the adapter, and is directly addressable by
the system processor. A viewable area of 1,024 x 768 pels is
supported, with most of the remaining bit map usable for font
storage.
       The adapter hardware provides significant system off-load as
well as fast front-of-screen response.  A high level interface is
presented to the system processor.  The hardware architecture of the
adapter supports a very fast rectangular area move, copy, merge,
fill, rotate, and replace, as well as logical operations and line
drawing.  Hardware cursor support is also provided.
       The adapter contains a high-performance list processor which
executes primitives from an on-card queue.
       Hardware assist on the card provides data alignment to the pel
level in either vertical or horizontal orientation.  Alphanumeric
text characters are treated as graphic symbols by the hardware, and
can therefore be tailored to a variety of shapes, sizes, or styles as
desired.
