Choosing Diskettes for the Equity II
When you buy diskettes, be sure to choose high-quality diskettes
with reinforced hub rings-the added reliability is well worth the extra
cost. You also need to make sure you buy the correct format type for the
drive(s) in your Equity II.
The top floppy disk drive on the Equity II has a storage capacity of
360KB (kilobytes) and uses 5 double-sided, double-density, soft-
sectored, 48 TPI (tracks per inch) diskettes. Each double-density disk can
hold up to 360KB of data, or about 150 pages of text.
(One
kilobyte
equals 1024 bytes.) These diskettes are compatible with those the IBM
PC uses, so you can use diskettes prepared by one computer on
the
other.
On the Equity II, a 360KB floppy disk drive
has a
PUSH button which
you press to hold a diskette in place.
If you have a second 360KB floppy disk drive, your bottom drive
uses the same double-density diskettes described above.
If your Equity II has a 1.2MB (megabyte) floppy disk drive, choose
5 %-inch, double-sided, highdensity, soft-sectored, 96 TPI diskettes for
this drive.
Each
highdensity diskette can hold 1.2MB of data, or about
450 pages of text. (One megabyte equals 1,048,576 bytes.) These diskettes
are compatible
with those the
IBM PC AT™ uses, so you can use diskettes
prepared by one computer on the other. On the Equity II, a 1.2MB floppy
disk drive has a latch which you turn to hold a diskette in place.
Before you can use new diskettes, you need to format
them.
Format-
ting erases any data stored on a diskette and prepares it to receive
new
data, so be sure to format only new blank diskettes or diskettes
that
contain data you want to erase. See your MS-DOS (or other operating
system) manual for instructions on how to format diskettes.
Drive and diskette incompatibilities
You need to be aware of some incompatibilities between 360KB and
1.2MB floppy disk drives and the diskettes they use. These incompatibil-
ities apply to diskettes from other compatible computers as well.
Although you
cannot
use high-density diskettes in a 360KB drive,
you can use double-density diskettes in a 1.2MB drive under the circum-
stances
described below.
