The ROM system is an unclassified system.
There are two types of software security associated
with the system: physical and application.
Physically, the ROM system terminal must be
located in an area accessible only to personnel who
have a need to use the system. The software
security is based on the concept of a users
authority to perform a given set of functions and
makes only the authorized set of functions
available. Access levels are determined by
password and user ID which will be assigned by
the ROM system administrator, usually the ships
store officer. The ships store officer will input
these access codes into the ROM system on a need-
to-know basis. Password/security instructions are
contained in appendix F of the ROM Terminal
Users Guide. The instructions are distributed
to the ships store officer only during the
implementation of the system. All persons having
access to the ROM system will be listed on the
ROM system security access rights list. This list
is placed in an opaque envelope. It is then sealed
and tape is affixed over the flap. The envelope
containing the ROM security access rights list,
along with the password/security instructions, and
appendix F of the TUG will be retained in the
ships store officers Accountability File (SSA-21).
The ships store officer will review the ROM
security access rights list monthly. If, for any
reason, the user ID and password of the individual
assigned sales officer are lost, the password file
provided during implementation, which includes
all users IDs and passwords, must be reloaded.
Data files set up during implementation should
therefore be maintained in a locked secure place
such as the ships store officers accountability
file. To reload the password file you should refer
to appendix F in the TUG.
THE ROM SYSTEM
The ROM system operates on a Zenith Z-248
and the Honeywell PC applications processor
(AP) microcomputer. Once you become an
authorized user of the ROM system you will
become familiar with the various keys on the
keyboard and their uses. The computer keyboard
is similar to a typewriter keyboard with additional
keys installed for special functions. Some of the
different types of keys and parts of the ROM
system are discussed below.
Special function keysThe special function
F keys include keys 1 through 10 and the Esc key.
The F keys are located on the left side of the
computer while the ESC key is located on the right
side on the Honeywell microcomputer. On the
Zenith Z-248, both the F keys and the ESC key
are located on the left side of the computer. The
function you select will be taken from the ROM
screen display that lists the choices available with
an F key or Esc key shown next to the description
of the function it performs. When you depress
one of the F keys, the function listed on the
display screen is activated.
Cursor movement keysThe cursor is a
special, blinking underscore character located on
the screen that can be moved to where the user
wants it. On the right side of the computer there
are four directional arrows that perform different
cursor movements. The left arrow moves the
cursor one position to the left while the right
arrow can move it one position to the right. The
down arrow moves the cursor down while the up
arrow moves the cursor up. For the four
directional arrows to perform cursor movement,
the light on the num lock must be off. If the num
lock light is on, the four directional arrow keys
become numeric keys and cursor movement
cannot be performed.
Display screenThe display screen on the
ROM is used to display and explain the informa-
tion needed so a response by the user can be made.
Information will appear on the screen as entered
and the cursor will indicate where the next
character will be entered.
Disk drivesThese are storage devices used
to transfer information into and out of the
computers memory. The Zenith Z-248 contains
two 5 1/4-inch floppy disk drives and two
Winchester disk drives. The Honeywell AP
contains two 5 1/4-inch floppy disk drives and
one Winchester disk drive.
The disk storage of the computer is organized
into files that contain one or more records.
Computer data records are like completed forms
in a file drawer. Each record contains several
fields. These fields are equivalent to blocks of
information on forms in a file cabinet. Just as
only one form type was filed in each folder, only
one record type is stored in each data file. In the
ROM system, for example, the data file called
ROMAS (Resale Operations Stock Record Master
file) contains information that is kept on the Stock
Record, NAVSUP Form 464. There is one record
in the ROMAS data file for each merchandise
item carried in stock. Each record contains a
