Atari Tempest - Printed-Circuit; Board Removal

Tempest™
F.
Printed-Circuit
Board
Removal
You
may
wish
to
remove
the
Analog
Vector-Gene-
rator
printed-circuit
board
(PCB),
Auxiliary
PCB or
the
Regulator/Audio
II PCB
for
service
or
inspection.
To
do
this,
refer to
Figure
15
and
proceed
as
follows:
1.
Open
the
rear
access
panel.
2.
Locate
the
hardware
that
secures
the
PCBs to
the
cabinet,
and
remove
this
hardware.
(The
game
PCBs
have one
set
of
this
securing
hard-
ware: a
screw,
washer
and
two
spacers.
The
Regulator/Audio
II
PCB
has
two
sets
of
this
securing
hardware:
a
screw
and
washer.)
3.
If you
are
removing
the
game
boards,
first re-
move
the
two
machine
screws
or tie
wraps
that
fasten the
edge
connectors
to
the
game
PCBs.
Then
unplug the
edge
connectors
on the
game
PCBs.
If you
are
removing
the
Regulator/Audio
II
PCB,
disconnect
the
five
small
harness
connec-
tors
on
this
board.
4.
Carefully
slide
the
PCBs
straight
out
of
their
slots.
The
Analog
Vector-Generator
and
Aux-
iliary PCBs
slide out together.
Be careful not
to
twist the boards, as
this may
loosen connec-
tions or
components.
Replace or
repair
as
re-
quired.
5. Reinstall the
PCBs,
making sure that
the con-
nectors are
properly plugged
in. Note that they
are
keyed
to
fit on
only one way, so
if they don’t
slip on easily,
don’t force
them! A reversed con-
nector will probably
damage your game
and will
void the
warranty.
6.
Replace the
securing
screws and fiber
washers
in the
PCB. Reinstall the
fasteners used
to
se-
cure
the edge connectors to
the
PCB. Close and
lock the
rear access
panel.
7.
Check that the
operation of the
game is correct
and perform
the self-test.
This is especially im-
portant with any game
when you
repair
a
PCB.
Normally the only
adjustments on this
game are
option switch
changes (made
on the 8-toggle
DIP switch).
Unless you
are
a
qualified techni-
cian, do
not turn any
of the knobs
near the game
PCB’s edge
connector.
Also do not turn the
small
knobs on the
Regulator/Audio
II PCB.
