       Description
       Attachment of a 5088 Graphics Channel Controller Model 1
to the host system channel provides control facilities for up to
16 (32 with the 5088 Model 2) 5085 Graphics Processors with 5081
Displays and/or 3251 Displays attached through a 3255 Display
Control Unit and/or an RS232C port connected device (see RS232C
devices section).
       An interactive workstation consists of a 5085 Graphics
Processor and a 5081 Display. Peripheral features (e.g., the
alphameric keyboard or 5083 Tablet) connect through the base of
the 5081 Display into the 5085 Graphics Processor.
       Peripheral options: Tablet, lighted program function keys,
dials, keyboards.
       The 5085 Graphics Processor permits the concurrent
attachment of a color and a monochrome model of the 5081 Display.
Additional displays may be cable-connected from either display
connected to the 5085. These displays must be the same model as
the display to which they are cabled. Any and all displays
attached to a single 5085 show the same picture.
       The IBM 5081 Display:  The display is the main interactive
vehicle for the user. Picture quality, display appearance, and
human factors have each received extensive development attention.
The display has the following characteristics:
.  Clear, comfortable view of the screen enhanced by an
   anti-reflective treatment in both the color and the monochrome
   models.
.  Contrast enhanced by a special filter additive in the glass of
   the display.
.  A 19-inch diagonal screen with a 1024 by 1024 pixel array
   displayed on an area approximately 284 mm/11.2 inches by 284
   mm/11.2 inches.
.  Sharp, precise images due to a small pixel spot size in both
   the color and the monochrome models.
.  Steady, bright image using special phosphors uniquely adapted
   to a 50Hz non-interlaced refresh rate.
.  Display controls for coarse convergence adjustment (color
   display only), picture centering, contrast and brightness, and
   four indicators for fault isolation are conveniently located
   at the front base of the display, behind a flip-down panel.
.  Compact dimensions - 490 mm/19.29 inches high, 490 mm/19.29
   inches wide, and 553 mm/21.77 inches deep.
.  Convenient tilt and swivel mechanism for user selection of the
   most comfortable viewing position - standard in the 5081
   Display.
.  RS343 attachment for the cable connection of an additional
   5081 of the same model number. All 5081 Displays connected in
   this way display the same picture.
.  Up to 256 simultaneously displayable gray shades (5081 Model
   1) or up to 256 colors (5081 Model 2) from a range of 4,096
   colors.
.  Attachment of peripherals via convenient plug-in connections

   located beneath the display at the front of the tilt-swivel
   base; the plug-in connections attach to the 5085 Graphics
   Processor via a single cable.
       The IBM 5085 Graphics Processor:  The 5085 has a
comprehensive graphics architecture that includes the 3250
Graphics Display System compatibility. The 5085 provides a
powerful graphics order set with more than 75 orders. The 5085
controls the workstation's display list buffers, concurrent
graphics and 3270 data mode sessions, peripheral device
attachments, RS232C attachment, and display functions. It may
contain up to 1.1 megabytes of system memory. A workstation is a
5085 with one or more 5081 Displays; all displays show the same
picture.
       IBM 5085 Graphics Processor Performance:  The new 5080
orders, in combination with the increased amount of 5080 system
memory available to the user and microprocessor graphics
functions in the processor, enables an application to
significantly offload host processing.
       The 5085 Graphics Processor uses multiple processors and
specially designed hardware to achieve the following performance
characteristics:
.  Hardware generated high speed vector to raster conversion:
   -   The pixel generator writes pixels in any direction at the
       rate of 100 nanoseconds per pixel. Actual drawing time
       varies based on the graphic order used and system
       variables such as dynamic RAM refresh time.
   -   Horizontal pixel write speeds in certain area fill
       operations may be accomplished at faster rates.
.  High speed fixed character generator using separate,
   dedicated, high performance memory.
.  Separate microprocessor to handle data transfers between the
   5085 and 5088 at the high rate of two megabits/seconds. Other
   microprocessors in the 5085 may perform parallel processing of
   display list and peripheral device control.
.  High speed display list order processing is provided by a
   16-bit bit-sliced processor.
.  High speed transformations (scaling, rotating, and
   translation) with coordinate clipping of two and three
   dimensional objects with the optional transformation and
   clipping feature (#1021).
   This feature may offload the host by permitting image
   manipulations and successive transformations in the 5085.
.  Calculation capabilities of arithmetic operations, including
   sine and cosine, along with stacking and concatenation of
   transformation matrices.
.  Separate microprocessor supplied with the optional 3270 and
   RS232C Attachment feature (#5510) to permit 3270 processing in
   parallel with all other operations.
.  Additional 192K memory included with the optional 3270 and
   RS232C Attachment feature (#5510) (used for the 3270 and
   RS232C microcode and communication for the RS232C ports).
.  Optional peripheral I/O units contain microprocessors that
   offload the 5085 and provide diagnostic functions.
       5085 Graphics Processor functional capabilities:  A single
model of the 5085 is available which has:
.  Compact size (590 mm/23.2' high by 320 mm/12.6' wide, by 568
   mm/22.37') for convenient office placement; fits beside a desk
   or under a table.
.  128K bytes of system memory for storage of display lists and
   5085 control programming (expandable to 1.1 megabytes with the
   addition of system memory features). In a system which has the
   base 128K bytes of system memory, 64K bytes are reserved for
   the 5085 control program. Of the remaining 64K bytes, an
   additional 8K bytes are reserved for these display list
   functions (as area fill workspace, area fill pattern and line
   patterns, and future expansion). The remaining 56K bytes, as
   well as any additional feature of system memory, is available
   to the user for storage of information for display lists and
   programmable vector character sets.
.  Optional System Memory feature (#6311) - 512K each to
   additional one megabyte of memory.
.  Polygon area fill - the functioned polygon fill has the
   following characteristics:
   -   Use of solid or user-defined fill patterns
   -   Filling of 2-D objects including those being dynamically
       transformed, (e.g., rotated, scaled, and translated) and
       clipped
   -   Filling of circles as well as concave and convex objects
   -   Filling of multiple overlapped and disjointed polygons
       that contain shapes (islands) and/or crossing sides
       (bowties).
.  Both fixed and programmable line type and character set
   generators.
   Four fixed line types and four fixed character sets are
   provided in the hardware. Fixed characters and line types are
   not scaled which facilitates reading of text and easy line
   type identification when a picture has been scaled.
   The programmable character generator permits users to define
   their own vector definitions for any character. These
   vector-defined characters can be scaled and rotated like any
   other vector the 5085 processes. Multiple programmable
   character sets and line types may be loaded in the 5085 system
   memory with the active programmable character set and line
   type dynamically selectable by the user.
.  Four simultaneously displayable colors or gray shades
   (expandable to 256 with the addition of Expansion Pixel Memory
   features #3621).
.  Automatic mapping of color to monochrome images to facilitate
   intermixing of color and monochrome displays.
.  3250 graphic order compatibility (see Compatibility section).
.  Double frame buffers facilitate smooth picture transitions
   without blanking or flashing.
.  Three-dimensional, 64K (X) by 64K (Y) by 64K (Z) virtual world
   coordinate space.
.  4K by 4K virtual image space mapped to the 1K by 1K real
   screen coordinates.
.  Bit-mapped images in the host displayed conveniently using a
   special graphic order.
.  Circle generation - circles that are scaled using the circle
   generation facility retain a smooth form without requiring
   host interaction.
.  Audible alarm with volume control.
.  Frame buffer write and erase protect function which
   facilitates animation, menu overlays, and visual detection of
   vector intersections.
.  Diskette drive (5-1/4') with a formatted capacity of 360K
   bytes used to store the 5085 microcode, error statistics, and
   configuration data; storing microcode in this way establishes
   an easy method for providing future enhancements with minimum
   customer impact.
       3270 and RS232C Attachment (#5510):  This optional feature
adds both a 3270 processor and the ability to attach RS232C
compatible devices.
       Feature #5510 permits an IBM 5080 Graphics System user to
access 3270 applications in host systems that support an SNA/SDLC
attachment. Separate interaction with 3270 and 5080 graphics
applications can be maintained simultaneously. The user may
alternate which image is shown on the 5081 Display by a simple
keyboard action. The integrity of the display images for both
applications is normally preserved by the 5085 Graphics
Processor. For exceptions, see Principles of Operations,
GA23-0134.
       By providing access to both 3270 and 5080 graphics
applications, the IBM 5080 Graphics System supports the data and
graphics computing needs of engineers and other professionals in
a single workstation.
       Feature #5510 supports the following 3270 functions:
.  Base 3270 functions.
.  Regular and high intensity for each of seven specified colors
   provided that a 5081 Model 2 (color) and at least one
   additional Expansion Pixel Memory feature (#3621) is
   installed. (It is recommended for systems with color 5081
   Displays that at least one additional Expansion Pixel Memory
   feature .#3621) be added in the 5085 Graphics Processor to
   achieve compatibility with color IBM 3270 displays.)
.  Screen sizes (80 characters per line):
   -   12 lines (960 characters)
   -   24 lines (1920 characters), as the default

   -   32 lines (2560 characters)
   -   43 lines (3440 characters)
.  Multiple partitions.
.  Extended highlighting, blinking, reverse video, underscore.
.  Field validation.
.  Audible alarm.
.  Alphameric keyboard with 24 program function keys.
.  APL using the APL keyboard and 12 of the 24 program function
   keys.
.  TP communications using SNA and SDLC protocols, external,
   self-clocked modems at speeds up to 9600 baud.  (The 3270
   Feature may be multidropped.)
       RS232C devices:  Two 25-pin RS232C attachment ports will
support devices that:
.  Conform to electrical interface specifications, EIA RS232C and
   CCITT V24.
.  Have a transmission protocol that can be supported using the
   generalized 5085 RS232C attachment interface architecture.
       The RS232C attachment port can support data transmissions
up to 9600 bps for ASYNC attachment. Two areas of 16K bytes each
(of the 192K bytes of additional memory provided with this
optional feature) are used for host-generated device protocols
and data that communicate with the RS232C-attached devices. This
is suitable for many devices, including the IBM 7374 and 7375
Color Plotters. Each activated RS232C port is addressed
separately by the host application using it and is considered one
of the addresses of the 5088 Channel Controller or the 3258
Channel Control Unit.
       When a device is attached to the RS232C port, it can run
concurrently with the graphics and 3270 capabilities.
       Peripheral Device Features
       Alphameric Keyboard: This feature is a low-profile, cable
attached, EBCDIC typewriter-like keyboard which can be adjusted
easily to any of three surface inclinations matching a user's
preferred hand position.
       The keyboard has 104 keys that may be operated with or
without audible feedback. The key arrangement has four clusters
of keys:
.  10 special function keys.
.  59 keys in QWERTY arrangement, plus special standard keys for
   engineering graphics.
.  11 keys for cursor control and the functions of shifting
   between 5080 graphic and 3270 modes.
.  24 program function keys arranged in two horizontal rows of
   twelve at the top center. (In 5080 graphics mode, these PF
   keys can be used in place of the first 24 lighted program
   function keys if lighted tops aren't required. Normal PF key
   function is supported in 3270 mode.)
       APL Keyboard: Use of APL is only supported via the
optional 3270 feature (#5510). The APL Keyboard has modified
keytops to allow the entry of 81 specific APL characters. Exit
and entry from APL entry mode is controlled through a special APL
on/off key. In other respects, the APL Keyboard resembles the
Alphameric Keyboard.
       Lighted Program Function Keyboard: The Lighted Program
Function Keyboard is a separate assembly with 32 keytops in which
amber-colored light emitting diodes (LED) are imbedded. The case
profile and surface inclination adjustment are designed to match
those of the Alphameric and APL Keyboards.
       The keyboard LEDs can be turned on and off under host
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 and an
application may interact. The keyboard functions operate
compatibly with 3250 programs.
       Dials: The dials are a flat, compact, low-profiled,
desk-top unit with eight, cone-like dials. The dials may be
turned continuously in either direction. Upon rotating the dials,
a range of scalar values indicating extent of rotation and
direction are signaled to the 5085 Graphics Processor. An
application can read and interpret this input for any suitable
purpose, such as panning, zooming, and rotating two or three
dimensional images.
       5088 Graphics Channel Controller: The 5088 operates as a
shared, high speed channel-attached controller for the
workstations. It may attach to a System/370/43XX/30XX channel
with a channel data rate of up to 2.5 megabytes per seconds in
data streaming mode or up to one megabyte per second in
conventional channel mode. Functional compatibility with the IBM
3258 permits attachment of IBM 3255s and 5085s. Since 5085s may
also attach to the 3258, the capability to mix units from the
5080 Graphics System and the 3250 Graphics Display System
protects customer's investments and eases migration.
       The 5088 functional capabilities include:
.  Compact size (590 mm/23.2' high by 320 mm/12.6' wide by 568
   mm/22.37'). (It has the same physical dimensions as the 5085
   Processor for easy placement.)
.  Attachment of sixteen 5085s and/or 3255/3251 workstations
   and/or RS232C-attached devices on a Model 1. The Model 2 has
   two sets of 16 attachments for a total of 32 attachments.
.  Each RS232C compatible device connected to feature #5510 or a
   5085 requires one 5088 or 3258 address. This applies, for
   example, to attachment of the IBM 7374 and 7375 Color
   Plotters.
.  Two-megabit per second data rate between the 5088 and 5085 in
   a 5085 configuration. (A 3255 attached to the 5088 reduces the
   data rate to any 5085 or 3255 attached to the same 5088 Model
   1 or to the same side of a dual 16-attachment, 32 total, 5088
   Model 2, to one megabit per second.)
.  Standard channel interface attachment at up to a 121.9
   meters/400 feet distance - block multiplexer, selector, or
   byte multiplexer (burst-mode) channels.
.  Use of either 3250 type (75 ohm) cable or 3270 type (93 ohm)
   cable for attachment to 5085 Processors.
   The maximum distance between the 5088 and a 5085 depends upon
   the attenuation characteristics of the cable and any
   connectors (customer supplied). Use of 3250 (75 ohm) and 3270
   (93 ohm) cable permits attachment up to 1,000 meters/3,280
   feet apart. The use of special low loss 75 ohm impedance
   coaxial cable may permit attachment up to 5,000 meters/16,400
   feet apart. See 'IBM 5080 Graphics System Site Planning and
   Preparation Guide' (GA23-0129) for details.
.  Efficient data transmissions by overlapped processing on the
   host channel and 5085 serial interfaces.
.  Channel transmission overhead reduced by processing data in
   blocks up to 64K bytes.
       The 5088 Graphics Channel Controller provides new channel
command capabilities which permit applications to use advanced or
extended functions in the 5085 Graphics Processor. Included in
these capabilities are:
.  Control of display lists that are greater than 64K bytes.
.  Select write/read memory area commands for minimizing channel
   utilization on large writes/reads.
.  Loading of programmable vector character sets into system
   memory.
.  Controlling allocation of 5085 memory for functions such as
   large polygon fills which require more than the default
   workspace.
.  Overlapping of device processing.
.  Additional sense information to assist in fault isolation,
   program debugging, etc. Sense information is provided
   separately for each 5085 device.
       The 5088 also supports the 3258 channel commands to assist
existing 3250 users in either mixing 5080 systems with 3250
systems or to permit the use of the currently available GAM or
GAM/SP Release 1 access methods. When the 5088 execution is
limited to 3258 channel commands, the performance characteristics
of the 5088 may be less than that of the 3258 depending upon the
amount of data that the application reads from the terminals. If
the reading frequency and/or volume of input data is low, then
the 5088 performance should be comparable to a 3258. (This is
normally the case for the IBM-supported CAD/CAM applications.)
       Additional RAS capabilities:
.  Enhanced 5088/5085 link problem determination capabilities.
.  Improved error detection.
.  I/O error alert.
.  Machine check broadcast to 5085 with optional automatic
       restart.
.  Power on/off remotely from the host CPU.

       The IBM 5083 Tablet:  The tablet is a thin, flat surfaced
unit of compact design, which offers a comfortable way for users
to interact with the display. It has a palm rest and a tilt
height adjustment mechanism. The x-y coordinate position of the
stylus or cursor is transmitted to the 5085 Graphics Processor.
.  Dimensions of 400 mm/15.75 inches wide, 431.5 mm/17 inches
   long, and 21 mm/0.82 inches deep which includes an active area
   of 292 mm/11.5 inches by 292 mm/11.5 inches.
.  Resolution characteristic of .127 mm/.005 inches.
.  Light weight (6.5 lbs. or 2.9 Kg) for use either on a work
   surface or a user's lap.
.  Cursor feature with a convenient hand-held 'mouse-shaped' unit
   with four buttons for application use and a fine cross hair
   for precise alignment and accurate digitizing of source data.
.  Optional stylus feature (pen-like device) for user interaction
   with the 5080 system. (An indication is provided to the
   application program when the user activates the stylus tip
   switch by pressing the stylus tip to the tablet surface. The
   tactile feedback from pressing the stylus tip assures the user
   that a selection has been made.)
.  3250 light pen emulation using the stylus or cursor feature
   (mutually exclusive, one feature may be attached at a time)
.  Thin cable connection

Display System, operate under Release 2 of the IBM Graphics
Access Method System Product (GAM/SP).  Under GAM/SP Release 1
with VM/SP or the Graphics Access Method (GAM) sub-component of
the graphics programming services component in MVS/370, MVS/XA,
or VS/1, support of the IBM 5080 is limited to the 3250 subset.
However, users are able to invoke extended 5085 function, such as
color, by coding display lists using appropriate 5085 graphic
orders. Larger than 32K byte display list buffers are not
supported. See GAM/SP Programming Announcement dated November 1,
1983, for details.
       Compatibility:  IBM 3250 Graphics Display System
applications should operate on an equivalently configured IBM
5080 Graphics System. Although the 5080 system is functionally
3250 compatible, there are certain incompatibilities due to the
use of a raster display (the 5081) to emulate a directed beam
display (the 3251) and to certain performance or function
differences. These differences are in the following areas:
.  Highlighting by overwriting of vectors
.  Vectors with a single endpoint off the screen
.  Never ending display list
.  Wrapping of vectors in coordinate space
.  Last position of an unprotected field
.  Buffer wrap
.  Address returned by GEOS (end of order list)
.  End of application
.  Time dependent display list programs
.  The 5083 Tablet in light pen emulation mode instead of the
       3250 light pen
       For explanations of each, see 'IBM 5080 Graphics System
Principles of Operation' (GA23-0134).
       The 3250 architecture is defined so that on a 1K x 1K
raster display, character truncation would normally occur around
the display periphery. A migration aid, called normalization, is
provided that allows the viewing of the entire 3250 screen
without program modification. (See 'IBM 5080 Graphic System:
User's Guide,' GA23-0130 and 'IBM 5080 Graphics System Principles
of Operation,' GA23-0134.)
       Relationship to 3250 performance -- The following
performance enhancements have been made to the 5080:
.  More information can be displayed on the 5081 Displays while
   maintaining a bright, sharp, steady image.
.  Higher host channel and serial interface speeds will provide
   faster data transmissions.
.  Larger blocks of data (64K bytes) may be transmitted using
   Graphics Access Method System/Product Release 2.
.  Overlapping of device processing using new channel commands.
.  One on one dedication of a 5085 processor's resources to an
   end user eliminates performance inconsistencies that may
   result from the 3255's resources being shared by up to three
   end users.
       The 3270 compatibility requires the optional 3270 and
RS232C Attachment feature (#5510). It is recommended for systems
with color 5081 Displays that at least one additional Expansion
Pixel Memory feature (#3621) be added in the 5085 Graphics
Processor to achieve compatibility with color IBM 3270 monitors.
       The 3270 programs can operate with the 5080 system using
host systems that support SNA/SDLC 3270 attachment and
applications that use the supported features.
       The 3270 functions and attachments not supported are:
.  Data entry keyboards
.  Numeric lock
.  Magnetic slot reader
.  Magnetic hand scanner
.  Loadable programmed symbols (PSS)
.  Multiple partitions with scrolling
.  Tablet emulation of a light pen
.  Keylock
       Security, Auditability, and Control
       The IBM 5080 Graphics System uses the security and
auditability features of the system control programs under which
it operates. User management is responsible for evaluating,
selecting, and implementating the security features for
administrative procedures and for appropriate controls in
application systems.
       Planning Information
       Customer Responsibilities:  The customer is responsible
for:
.  Physical planning and site preparation, including required
   electrical service and facilities. See 'IBM 5080 Graphics
   System Site Planning and Preparation Guide' (GA23-0129) for
   details on the above responsibilities.
.  Setup and installation of:
   -   5081 Display.
   -   5085 Graphics Processor and peripheral features (lighted
       program function keyboard, alphameric keyboard, dials).
   -   5083 Tablet with stylus or cursor features.
   Note: The 5088 is installed by Field Engineering.
.  Education of 5080 Graphics System users
.  Ordering and installing appropriate cables.
.  Ordering and installing modem and communication lines for use
   with the 3270 and RS232C Attachment feature (#5510).
       For the 5088: Cables to the System/370/43XX/30XX processor
must be ordered.
       For the 5085: Cables to the 5088 or 3258 are a customer
responsibility to supply. Cables from the 5085 to the first 5081
are supplied with the 5085. The 3270 and RS232C Attachment
feature (#5510) includes one ten-foot cable for attachment to

modems with EIA connectors.
       For the 5081: The attachment of external output only color
or mono displays require a video coaxial cable that is the
customer's responsibility to supply.
       See IBM 5080 Graphics Systems Site Planning and
Preparation Guide (GA23-0139)
       Installability: Minimum configurations are:
.  5088 Graphics Channel Controller Model 1 or 2 (or 3258) (note
   that a 5088 may also be used in place of the 3258 in the 3250
   Graphics Display System).
.  5081 Display Model 1 or 2.
.  5085 Graphics Processor Model 1 with an alphameric keyboard.
