*   5271 Model 26
    -   Same as the Model 24, except that a single dual-sided
        diskette drive and one 10MB fixed disk and fixed disk adapter
        replace the two dual-sided diskette drives.
*   The 5271 System Unit Models 24 and 26 include the display adapter
    for the 3295 monitor. Key functions are:
    -   Up to 9,920 alphameric character MFI display
    -   Up to 2,000 alphameric character PC display
    -   IBM PC Color Graphics Adapter APA compatibility with three
        shades of orange plus black instead of color
    -   3270 programmed symbols.
       The 3295 Plasma Monitor has a large distortion free viewing
area (960 x 768 picture elements on a 13.44" x 10.75" surface).
Characters are orange on a black background.  It utilizes the IBM
plasma panel technology as its viewing medium. This provides uniform
image clarity at every point of the viewing area and allows a smaller
footprint than achievable by CRT monitors of equivalent size. Overall
dimensions are:  width -- 580 mm (22.8"), height -- 496 mm (19.5"),
and depth -- 200 mm (7.8").
       When attached to a 5271 System Unit Model 24 or 26, the 3295
provides the user with large display capacity. Two character sets are
available through a workstation control function; the small character
set utilizes a 6- x 12-pel character box and an alternate character
set utilizing a 9- x 16-pel character box. With the small character
set, 9,920 characters can be displayed in a 62-row by 160-column
matrix; when using the larger character set, 4,876 characters can be
displayed in a 46-row x 106-column matrix. The small character set
allows four 2K-character screens to be viewed concurrently.
       The large-screen models of the 3270-PC system are primarily
intended for environments which require concurrent viewing of more
than 2K characters using larger than 2K windows or multiple 2K
windows where the primary applications are host related and the user
profiles are relatively static.
       The 3270-PC Control Program Version 1.2.1 has been updated to
support the large screen 3295.
       The 3270-PC (5271 Models 24 and 26) attaches via the IBM 3274
Control Unit to System/370 processors and processor complexes, 30XX
processors, and 43XX processors. All attachment environments are
supported, i.e., SNA local channel, non-SNA local channel,
synchronous data link control (SDLC) remote, or binary synchronous
control (BSC) remote. Attachment to the 3274 is by coax cable.

TECHNICAL INFORMATION
SPECIFIED OPERATING ENVIRONMENT
HARDWARE REQUIREMENTS: The 3270-PC (5271 Models 24 and 26) attach via
an IBM 3274 Control Unit to System/370, 30XX, and 43XX processors.
All attachment environments are supported, i.e., SNA local channel,
non-SNA local channel, synchronous data link control (SDLC) remote,
or binary synchronous control (BSC) remote. Attachment to the 3274 is
by coax cable.
SOFTWARE REQUIREMENTS: The IBM 3270-PC Control Program Version 1.2.1.
The 3270-PC is data stream compatible with all models of today's IBM
3270 displays in alphameric application environments with the
exception of host partitioning. There is no partitioning support in
the 3270-PC.  With this exception, existing host alphameric
applications will run on the 3270-PC unmodified (in their current
screen size). No programming changes are required of current
alphameric applications unless the program is affected by 3274
Control Unit configuration restrictions (e.g., no Category B
terminals) or required hardware functions not available with the
3270-PC (e.g., magnetic readers, encryption/decryption, or APL/text
characters).
       The 5271 Models 24 and 26 will accept 3270 data streams and
support programmed symbols (PS) graphics. Note:  The PS capability is
limited to five 192-character buffers when a PC session is in use;
programs written for PS assuming six PS buffers are available should
be tested for acceptability. There are six PS buffers available when
no PC session is being used. The multiple screen facilities of the

3270-PC can be used without any modification of system software.
       Most IBM PC applications that run on the IBM PC Color Graphics
Adapter will run on the new system units. Three shades of orange plus
black are supported in place of color. Applications that utilize
animation should be tested for acceptability prior to use.
SECURITY, AUDITABILITY, AND CONTROL
       The non-display control allows the password (or other
sensitive data) not to be shown on the command line.
       For transmission of sensitive data on public communications
facilities, customer management may wish to examine the use of
cryptography. Internal encryption/decryption is not available.
       The 3270-PC supports the security features of the operating
systems which control communications with the host system.
       Customer management is responsible for the selection,
application, adequacy, and implementation of these features and for
the appropriate application and administrative controls.
PLANNING INFORMATION
CUSTOMER RESPONSIBILITIES: The customer is responsible for:
*   Adequate site, system, and other vendor preparation
*   Receipt at customer's receiving dock, unpacking, and placement of
    unit
*   Physical setup (including any special mounting procedures and or
    hardware), connection of cables in customer access areas, switch
    settings, and checkout. The customer set-up allowance (CSU) is
    one day. Detailed set-up instructions are included with each
    machine. IBM set-up is available at IBM hourly rates and minimum
    charges.
*   Contacting an IBM customer service coordinator for attachment of
    the 5271 communication cable to an on-site serviced IBM control
    unit where customer access area is not provided
*   Customizing the 3270-PC and 3274 (see 3274 Customizing Guide,
    GA23-0065 or GA27-2827)
*   Determining the required number of spares
*   Performing customer problem analysis and resolution (CPAR)
*   Testing other IBM Personal Computer options not included with the
    3270-PC to assure viability (IBM does not accept any
    responsibility for them.)
*   Protecting data from modification, destruction, or disclosure,
    and for accuracy and integrity of results
*   Providing a back-up copy of the system
*   Installing the required programs.
INSTALLABILITY: The 3270-PC is a customer set-up system. It attaches
to one terminal port and may have up to four addresses associated
with it in the 3274, depending on the application. The 3270-PC is
3270 compatible in alphameric application environments; current
alphameric applications will run unmodified, excepting those that use
host partitioning. Host partitioning is not supported.
LIMITATIONS:
*   Because of the differences in plasma monitor technology and CRT
    technology, applications using animation and/or scrolling should
    be tested for acceptability prior to use. When using IBM PC APA
    graphics, three shades of orange plus black are used to
    differentiate color on the 3295. The APA resolution on Models 24
    and 26 is 640 x 200 pels. The 3270-PC APA applications using
    different screen resolutions should be tested for acceptability.
*   The 3852 Color Graphics Printer is not supported.
*   The 5201 and 5216 letter quality printers are supported for
    printing from the PC DOS application session only.
*   Color display is not supported. (IBM 3295 is a monochrome
    monitor.)
