DISK DRIVE UTILIZATION
The basic ADVANTAGE has two disk drives. The upper disk drive, #1, is usually reserved for
system diskettes. Each system diskette contains an operating system and may also include the
application program to be run. Only system diskettes for the ADVANTAGE can be used on this
computer.
The lower disk drive, #2, is usually reserved for data diskettes. A data diskette stores the information (for example, the text or accounting files) that you generate with a particular system
diskette. Data diskettes and programs such as FORTRAN and COBOL that do not incorporate
an operating system can be used interchangeably between the North Star ADVANTAGE and
a North Star HORIZON.*
2.3
INSERTING DISKETTES
Before you insert any diskette in the system, make sure the computer is turned ON.
Likewise, do not turn the computer off until you have removed all diskettes.
Take the system diskette you want to use and
remove it from the protective envelope. Be
sure to hold the diskette by the label or
some portion of the plastic jacket (Fig. 2-3).

* The one restriction is that quad capacity diskettes generated on the ADVANTAGE cannot be used on a HORIZON
that has only dual capacity drives.
