NOTE:
The Printed Circuit
Board
(PCB)
in
the
AMIGA is mapped
with
letters
along the
front edge
of the
PCB
and
numbers up
the left
side. Map
locations
for items
described in
the
text are
listed as
the
intersections
of these
points.
An
indication of
C2,
for
instance,
indicates the
board area
where a
line,
running
vertically
from the 'C
marked
on
the
PCB edge
and
horizontally
across
from the
'2'
printed
on
the
left
of the
PCB,
intersects.
The
map
points
in
this
text
are
estimates
of the
PCB
area
in which
a
connector
or
screw
may be
found.
