System Overview
Welcome to the HP 250 Offi~e Computer System. The HP 250 is an
easy-to-operate business~omputer that allows you to enter, pro-
cess, and access information, and output reports in the form of
hard-copy print or on a display screen.
The HP 250 Office Computer can be used in a variety of environ-
ments, from small single-user configurations to larger systems
capable of processing several tasks. From any starting configur-
ation, the system can be expanded to meet growing business needs.
To allow for this flexibility, the HP 250 has been designed as a
series of components. Each system consists of four major compon-
ents: the central processing unit, the workstation, the mass
storage device(s), and the printer(s). The central processing
unit is the "brain" of your system. You talk to it via the key-
board of your workstation, which resembles an office typewriter.
The display, a television-like screen, is useful for viewing in-
put data and for filling forms. The mass storage devices are
used for storing and accessing information and programs. The
actual storage medium may be a disc or a tape cartridge. The
printer is used to produce hard-copy reports which contain the
information required in the day-to-day operation of your busi-
ness.

This manual is organized to be read sequentially. Chapters 2
through 4 contain the background information necessary to turn
the system on, understand your workstation keyboard and its fea-
tures, and interact with the computer.
Chapters 5, 6, and 7 get you acquainted with the different types
of storage devices, storage media, printers, and graphics devices
that may be part of your HP 250; it is important that you recog-
nize the relationships between the components of the system.
Once you understand the different components of your HP 250 sys-
tem, proceed to Chapter 8. There you will find several HP 250
BASIC Commands that will be useful in the day-to-day operation of
your system.
Chapter 9 and 10 describe typical maintenance procedures and what
to do if you encounter a problem with the system.
The appendices provide reference material that you may find occa-
sionally helpful (such as error messages). Words printed in bold
type throughout the manual appear in the Glossary (Appendix A).
As stated before, you may find that some of the material in this
manual is not applicable to your particular configuration or your
daily task. We do recommend, however, that you hold onto this
information for future reference. You may someday add a printer,
workstation, or mass storage device to your system. Additional-
ly, your daily responsibilities may not require some of the mate-
rial presented here, but you should take the time to read it any-
way; that way you will know where to find the answer to a ques-
tion that may come up.
Even though various HP 250 configurations look physically differ-
ent, you will have no problem operating your system once you rec-
ognize and understand the different components.
Finally, you should remember that this guide is not a programming
manual. The information presented here is what you need to oper-
ate your HP 250 system. If you need programming information, you
should consult the appropriate manual, which is included in the
HP 250 Programming Manual Kit.

System Start-up
After a Hewlett-Packard Customer Engineer has installed your HP
250 system, it is ready to operate.
Starting up (or loading) your system can be compared to starting
an automobile. Your car must have fuel in it before you can suc-
cessfully start it by turning the ignition key. In the same way,
your HP 250 must have a version of the system software available.
This system software may be stored on a fixed disc or on a remov-
able medium such as a tape cartridge or flexible disc. It is the
"fuel" required to start your system.
Once you have successfully started your system up, turn it off
only when you are sure that no other task will be affected. For
example, you may have completed your work and are now ready to
leave the office for the day. If you shut any part of the system
down (including a disc drive), you can affect work being done by
another person.
Loading From an Integrated Storage Unit
An Integrated Storage Unit consists of two different storage
devices - a cartridge tape drive and a disc (HP 7908, 7911, or
7912). When your system first arrives, you can start it from a
tape cartridge only. Once you have successfully started the
system using a tape, you can then run the ROUTIL Utility Program
to copy all.files on a tape over to the disc; doing this allows
you to start your system from either a tape cartridge or the
disc. See the HP 250 System Utilities Manual (45260-90061) for
information on the ROUTIL Utility Program.
Loading from the Cartridge Tape Drive
The following is the procedure for loading your HP 250 system
from the cartridge tape drive.
1. Turn the Integrated Storage Unit power switch to the ON posi-
t ion.
