ABOUT THIS GUIDE

Since the introduction of the Personal System/2 family on April 2, 1987, a
wide variety of system models, memory modules, memory expansion adapters,
and fixed disks have been introduced. While this broad product line offers
IBM customers unparalleled flexibility, it can also make the tasks of
selecting, configuring, or expanding systems seem complex and sometimes
daunting. The following tables simplify the tasks of selecting,
configuring, and expanding the various members of the Personal System/2
family. The information contained herein applies to all systems, displays,
memory, and disk features introduced in the United States between April 1,
1987 and June 21, 1989.

To assist in the system selection process, information is provided on the
base system features, expandability, and usability. Much of what
distinguishes an IBM system from that of the competition is a careful
attention to the details of human factors design that cannot be measured
with simple numbers; nonetheless, even comparisons of those traits that can
be measured reveal the benefits of IBM's concern for every aspect of system
design. Reliability, expandability, size, weight, noise output, power use,
and electromagnetic radiation levels can and should be compared during the
system selection process. In making the system selection decision, it is
also important to consider performance. Therefore, it is important to
understand why benchmarks and performance comparisons are not included in
this guide and to place in context many of the performance indicators that
are provided.

Benchmarks are useful only to the extent that they are clearly recognized to
be a limited measure of a specific component of a complex system. Rarely
can any one benchmark, data point, or set of benchmarks crystallize the
essence of system performance into a single comparative number. More often,
they lead to misguided decisions based upon improper interpretations of
system performance characteristics. Even worse, benchmarks are often used
to justify inappropriate system selection criteria and weightings far
removed from the realities of daily use. Total system throughput and
application performance are comprised of many interrelated factors; a
bottleneck in one system subcomponent can easily negate supposed performance
benefits from another ultra-fast system subcomponent. Without a complete
understanding of the interrelationships of every subcomponent of the
systems, decision makers might be swayed by marketing pitches that emphasize
the specifications of certain sub-optimized components or carefully selected
benchmarks that often demonstrate performance characteristics unrelated to
actual system throughput in daily use. No benchmark or single measurement
should ever replace actual use or trial as the primary microcomputer system
selection criterion.

Another critical consideration is that benchmarks almost always
single-mindedly exclude reliability comparisons from performance
considerations. This rewards companies that design for performance over
reliability. In general, during system design, performance can be bought at
the expense of reliability. IBM designs to optimize system reliability and
provide overall system throughput through balanced system design rather than
to maximize individual component specifications. Thus, IBM systems will
perform very well when measured by throughput or user perception of
performance and extremely well when measured to include system integrity
lapses as significant negative performance indicators.

Finally, most benchmarks that have been published to date measure PS/2
performance under single-thread benchmarks that miss the entire design point
of the multi-tasking, Micro Channel-based Personal System/2. It is somewhat
analoguous to comparing a rocket to a jet plane using maximum attainable
speed as the benchmark criterion. The jet may not perform like a rocket if
orbiting the earth is the objective, but it will more likely meet the needs
of those who are interested in destination flexibility and smooth take-offs
and landings.

We invite you to experience Personal System/2 ergonomics and performance
first-hand before making system selection decisions and hope that this guide
makes a valuable contribution towards helping you find the system and
configuration that meets your needs.

NOTES:

* Systems listed as requiring a variable number of states use Page
Memory Logic. Accessing memory outside the most recently used page
(one page 2KB) requires one wait state. Writing data to memory
also requires one wait state. Therefore, read access from the
current page requires no wait states, read access outside the
current page or a write to the current page require one wait state,
and a write outside current page requires two wait states.

*0 Includes IBM Space Saving Keyboard.

*1 One available slot is a short slot, i.e. half-slot

*2 Includes built-in display as part of base system.

*3 Requires special consideration involving configuration and
availability of conventional vs. extended, and/or expanded memory.
You may need assistance in determining suitability to your needs.

*4 To ensure proper operation of the diskette drive, this model
requires the DASDDRVR.SYS device driver when running DOS 3.30. The
driver is not required when running OS/2 or DOS 4.00.

*5 Expansion adapter memory that runs at 120ns adds a wait state for
processor access to that memory.

*6 Requires the replacement of the standard 1MB module(s) on the
system board with 2MB module(s).

*7 128K of system memory is mapped for use by BIOS in order to improve
system performance.

*8 Expansion adapter memory and system board expansion memory are
rated at 80ns or 85ns.

*9 Includes 30ns 64K memory cache. Cached data is accessed with zero
wait states. For even more demanding applications, the performance
of the Model 70-A21 can be significantly enhanced via the The
Personal System/2 (R) 486/25 Power Platform, Feature #5220, Part
6450876. This upgrade includes a 25MHz Intel i486 32-bit
microprocessor that features an internal memory cache controller,
an internal 8Kb cache, and an internal floating-point processing
unit that performs the functions of an external 80387 Math
Co-Processor.

TABLE 2. IBM Personal System/2 Memory Expansion Alternatives by Model
===============================================================================
Applicable memory expansion features for each model

* Memory expansion alternatives are either SIPs (Single In-line
Packages) or Adapters. SIPs may be used to expand the system board
(Planar) or adapters or both, as noted.

* On all systems with more than 640K standard memory, the extra
memory is system board memory mapped beginning at the 1MB
address. On 80286-based systems, this memory can only be used as
extended memory. On 80386SX and 80386-based systems, this memory
is extended memory that can be used as expanded memory with the
appropriate drivers.

* Throughout all tables, x = any substitutable character,
e.g. 857x-x61 = 8570-E61 and 8573-061.

NOTES:
* These models come with four system board memory spaces, two of which are
occupied with replaceable 256K SIPs for a total of 512K. One 0.5MB
Feature #3397, consisting of two 256K modules, can be added for a total
of 1MB. Alternatively, the original system board SIPs can be replaced
by one or two of the 2MB Feature #7833, each consisting of two 1MB
modules, for a a total of 2MB or 4MB system board memory. Different
size SIPs cannot be used together on the system board.

* The ability to use a non-IBM memory expansion card in the Personal
System/2 Model 30 286 is dependent on the flexibility of the card in
establishing its starting memory address. To operate properly in the
standard Model 30 286 with 512KB, a memory expansion adapter must
support a starting memory address of 512KB. To operate properly in a
Model 30 286 with 1MB, 2MB, or 4MB of system board memory, a memory
expansion adapter must support a starting memory address of 384KB plus
the amount of system board memory.

* There are three AT-bus compatible slots available for adapter expansion.

*1 The PS/2 Multifunction Adapter, Feature #8635 can only be used with the
original 512KB of memory on the system board. Additional memory modules
may be moved from the system board to the PS/2 Multifunction Adapter.
Up to two PS/2 Multifunction Adapters may be installed, providing a
maximum of 15MB of additional extended memory. This adapter does not
support the IBM 3270 Workstation Program Versions 1.0 or 1.1 or the DOS
4.00 expanded memory drivers, but does support LIM EMS 4.0 when used in
conjunction with Above Disc (R) 2.0, which is not included with the
adapter and must be purchased separately (Order Vehicle 5871-AAA/Feature
#5448/Part 30F5448). Above Disc (R) works under PC DOS Version 3.30 or
higher. This adapter also includes one parallel and one serial port.
When two Multifunction Adapters are installed in the same system, it is
necessary to disable the serial port on the system board in order to
achieve full operation of three parallel and two serial ports.

Above Disc (R) is a registered trademark of Teleware West Company.

NOTES:

* All PS/2 memory expansion alternatives listed (with the exception of 8086
and 80286 planar memory and Model 30 286 memory) offer memory which can be
used as expanded memory using the drivers provided under DOS 4.00 (for
applications written to Lotus/Intel/Microsoft EMS Specification 4.0).

* All PS/2 memory expansion alternatives listed (with the exception of 8086
memory) offer memory which can be used as extended memory (for OS/2,
VDISK, or IBMCACHE).

* To improve performance under certain circumstances, it is generally
advisable to fully populate the system board before adding adapters.

* When using the IBM Workstation Program, special considerations apply
involving configuration and availability of expanded memory. You should seek
additional assistance to determine the appropriate memory configuration.

*1 The IBM 2MB Expanded Memory Adapter/A, Feature #3920, comes fully
populated with four sets of modules identical to the 0.5MB Feature
#3397, which consists of two 256K modules. The adapter can be expanded
from the standard 2MB configuration up to 8MB by replacing any or all of
the eight 256K modules on the board with the 2MB Feature #7833, which
consists of two 1MB modules. Once removed, two of the 256K modules can
be used as if they were the 0.5MB Feature #3397.

*2 The IBM Personal System/2 2-8MB 80286 Memory Expansion Option, Feature
#8286, should be placed in a higher numbered slot than Features
#3920 or #7259 when used concurrently in the 8550-021, 8560-041, or
8560-071.

*3 The IBM Personal System/2 Multifunction Adapter, Feature #8635, includes
one parallel and one serial port in addition to memory expansion spaces.
This adapter supports LIM EMS 4.0 only when used in conjunction with
Above Disc (R) 2.0, which is not included with the adapter and must be
purchased separately (Order Vehicle 5871-AAA/Feature #5448/Part 30F5448).
Above Disc (R) works with DOS Version 3.30 or higher.

NOTES:
* All systems are classified by the FCC as Class B, suitable for home use.
FCC Class B is a more stringent classification than FCC Class A.
Thus, the addition of a Class A adapter such as the Token Ring Adapter,
could make the systems unsuitable for home use.

* All systems are UL 478 approved.

* All systems except the Model P70 386 (see next note) have been tested to
operate properly when the air temperature is at least 60 F (15.6 C) and
not more than 90 F (32.2 C) with relative humidity between 8% and 80%.

* The Model P70 386 has been tested to
operate properly when the air temperature is at least 50 F (10 C) and
not more than 95 F (35 C) with relative humidity between 8% and 80%.

* All color displays (8512, 8513, and 8514) are capable of displaying up to
256 colors simultaneously from a palette of 262,144 colors at varying
resolutions depending on the graphics adapter and the amount of graphics
memory available.

* The 8503 and 8507 displays can display 64 shades of gray simultaneously
at at varying resolutions depending on the graphics adapter and the
amount of graphics memory available. Application colors are
automatically converted to gray shades via color summing.

* The 8506 and 8508 displays can display up to 16 shades of gray from a
range of 256 shades of gray at varying resolutions depending upon the
amount of memory on the PS/2 Image Adapter/A.

* All displays require an input voltage of 100 - 125 Volts AC with a
frequency of 50-60 Hz.

* All displays have been tested to operate properly when the air
temperature is at least 15.6 C (60 F) and not more than
32.2 C (90 F) with relative humidity between 8% and
80% at altitudes not greater than 2,134 meters (7000 feet) above
sea level.

* Both the power cord and signal cord on all displays are 1.8 meters (6
feet) in length.

* All displays are classified as Acoustic Class 1 (no fan or other noise
source).

APPLICATIONS (9)

NOTES:
(1) If you do not wish to concurrently execute all installed functions and
applications, then the memory required will be less. In this case, the memory
required would be the sum of the Operating System Base and the particular
functions and applications the user wishes to execute concurrently as well as
an allowance for user data.

(2) These numbers reflect the working set of the OS/2 functions listed and not
the total size of all of the code and data areas that comprise the functions.
The quantities shown assume that an acceptable degree of segment swapping is
occuring in the operational environment. To estimate memory requirements, add
together the recommended memory size for the operating system base and each
installed function and application together with an allowance for user data
buffer requirements. Using less than the recommended memory size will increase
the time to switch from one function to another, reduce throughput, and
increase the size of the swap file.

(3) Automatically installed; but may be removed by designating PROTECTONLY=YES
in the CONFIG.SYS file. The DOS compatibility session itself uses no
additional disk space; however, requirements for DOS compatiblity session
applications should be obtained from the applications' supplier(s).

(4) Testing indicates a 2.5MB swap file is typical; however more or less file
space may be necessary. To improve disk performance and to reduce file cluster
fragmentation, many users dedicate a 2-5MB fixed disk partition separate from
data or program storage as the swap drive with SWAPPATH=d: in the CONFIG.SYS
file.

(5) Required per session for concurrent file transfer.

(6) Memory size requirement is for a single database application. Subsequent
applications require additional memory, but less than the first.

(7) The Communications Manager must be installed for the LAN Requester or OS/2
LAN Server functions.

(8) Includes the Communications Manager LAN Requester files which must be
installed before the IBM OS/2 LAN Server.

(9) All sizes are estimated and are application/user dependent.
