Installing Memory Modules

To

install

a

SIMM

in

one

of

the

RAM sockets:

1.

Disconnect

the

Amiga

and

remove

the

cover,

as

described

in

Chapter

2. Remove

any

expansion

boards

in

the

daughterboard

slots.

3. Locate

the

proper

SIMM socket.

4.

Remove

the

existing

SIMM

if

necessary.

5.

Insert

the

new

SIMM carefully

into

the

socket,

as

illustrated

in

Figure

Insert

the

connector edge

of

the

module first,

then

press

the

opposite edge down

and

in

to

seat

the

module. SIMMs

are

notched

to

ensure

proper

orientation

in

the

socket.

Be

that

each

module

is

fully

seated

and

locked

into

place

by

the

tabs

at
