Operating Systems
Introduction
The information contained in
this section is both reference
and operational in nature. We
will give you background
information on operating
systems.
The information of specific
operating systems has been
divided into two parts, CP/M-86
and MS-DOS. The
PEOPLE
Personal Microcomputer offers
both these operating systems.
Read this section of your User

Background Information on
Operating Systems
The operating system is loaded
from the system diskette into
working storage (see Section 4).
It is a collection of programs that
forms the nucleus of the total
system. The operating system
controls the overall operation of
the computer. It performs such
tasks as allocating places in
memory to data and programs,
and controlling the overall input/
output of the system by coordi
nating hardware and software.
The operating system makes a
dialogue between the user and
the computer possible through its
“ routines” . These basic routines
continuously make all system
functions available to the user,
while simultaneously allowing the
computer to execute your system
commands. Such functions in
clude accepting keyboard
instructions, transferring informa
tion to the screen or to the
printer, organizing working
storage and the disk drives, as
well as chronologically monitoring
and registering all system tasks.
Without the operating system you
could not even load and use your
particular application program. Of
course, the application program
must always be compatible with
the operating system you’re using
at the time; that is, a spreadsheet
package written to run under
MS/DOS will not run under
CP/M-86 without modifications.
Various operating systems will be
offered for the
PEOPLE
Personal
Microcomputer. At present, these
include CP/M-86 and MS/DOS.
Additional operating systems are
under preparation.
A brief discussion of CP/M-86
follows here with further
information on the MS-DOS
operating system. More detail
on CP/M-86 and MS-DOS can
be obtained from the User
Manual for that particular
operating system.
