Radio Shack TRS-80 Trsdos & Disk Basic Reference Manual

Mini
Disk
Operation
Power-Up
Sequence
You should always
power
up
the
peripherals (disk drives, printer,
Expansion Interface,
etc.)
first, and the TRS-80 CPU/keyboard
last.
Also note that turning
the
peripherals on and off while the Computer
is on may confuse
the system
and
cause
abnormal operation.
Work
done on a currently
open
file may be lost.
The
power switch for
each Mini
Disk is on the
rear of the unit.
Power
is "on"
when the toggle
switch is in the up
position,
and "off when
the
switch is down.
1
.
Turn on
the
Expansion Interface.
2. Turn
on
the Mini Disk drives: first the terminal drive,
26-1
160,
then the other drives, if any.
3.
When
you turn
on the
TRS-80 CPU/keyboard,
the Computer
will instantly attempt to load
TRSDOS from Drive
0. So before
turning
on the
CPU, carefully insert the
TRSDOS
diskette into
drive as explained above under
"Inserting
a
Diskette". You
may
also
want to
insert formatted diskettes into the other drives
now; however, these
may
be
inserted any time the drives are
stopped.
Another
approach would
be to plug
all devices
into
an
adequate
power strip and
turn them all
on with
a
single
switch.
Care
of
Diskettes
Diskettes
are precision recording media. Handle
them very carefully
to
get maximum
life from each diskette. In general, follow
the special
handling
precautions used with both tape cassettes and
high fidelity
records.
1.
Keep the diskette in its storage envelope whenever it is
not in
one of the drives.
Don't
leave the diskettes in the drives
needlessly, for example, when the system is
turned off.
2. Keep diskettes away from magnetic fields (transformers,
AC
motors, magnets, etc.). Strong magnetic fields will
destroy
information on the diskettes.
3.
Handle
the diskette by the
jacket
only
—
don't touch any of the
exposed
surfaces.
Don't
try to
wipe or clean
the diskette
surface;
you
might scratch it and
destroy
data.
4.
Keep
the
diskette
away
from heat and
direct
sunlight. See the
"Specifications"
section
below for
storage temperature
range.
