TinyTurbo
286
INSTALLATION
The
TinyTurbo
286 works in computers that 3rc
hardware
compatible
to
the
IBM PC
and
IBM
XT,
and that
contain
an 8088 microprocessor on a
socket.
TinyTurbo
fits
in a normal IBM
expansion
slot
and
uses the host computer's
8088 socket.
It
consumes
about
7 Watts
of
power.
CAUTION:
Do
not
install
the
TinyTurbo
in
a
computer
that
contains
an
8086, 80186,
or 80286 microprocessor. You
might
damage
the
TinyTurbo.
JUMPER
SETUP
Before
installing
the
TinyTurbo
in your
computer, make sure the jumpers are set
for
your
configuration.
The
factory
configuration
of
the
TinyTurbo
is
as follows:
o 5MHz 80287
math
chip
o
Caching
enabled
o A host computer
with
640K
of
memory
You can
change
the
configuration
by
moving
the
jumpers as required. The jumpers on the
TinyTurbo
are
clearly
marked. Their
functions
are
given
below.

To
install a jumper, the black
plastic
sleeve
must covcr two opposite pins,
with
a pin in
each hole
of
the
sleeve.
If
it is hard to get
a grip on a jumper, try
using
the Ie extractor
tool that comes
with
your
TinyTurbo.
80287
MATH
COPROCESSOR
CHIP
The
TinyTurbo
286 comes
with
a socket for an
8MHz
or
5MHz 80287
math
chip.
To
install
it
on the board,
follow
these steps:
1.
Insert it in the
socket
so that the
indentation
on the end
of
the top
surface
of
the
chip
is at the same end
of
the
socket
as the socket's
indentation.
2.
3.
Make sure all
of
the pins are
aligned
with
their corresponding holes in the
socket
and
press
down
firmly.
Be
careful
not to
allow
any
pins to bend.
If
you bend some, be
careful
straightening
them, because the pins can
only
be
flexed
a
few
times
before
breaking.
Install the jumper on the pins that
correspond
to
the
80287's
clock
frequency.
either
5MHz or SMHz.
The
chips
are
usually
marked as follows:
8MHz
-80287-8
5MHz -80287-3
or
80287
