INSTALLATION INSTRUCTIONS

I. RECOMMENDED LOCATION

The recommended location for the Saturn 64K or 128K RAM

board depends upon whether an Apple Language card, 16K RAM

card, or firmware card is already present in the system.

1. If a Language card or 16K board is in slot 0, install the

Saturn 64K or 128K RAM board in any available slot.

2. If an Applesoft or Integer firmware card is already present

in slot 0, remove it from the system or move it to another slot.

Install the Saturn RAM board in slot 0.

3. If no card is present in slot 0, install the Saturn board in

slot 0.

II. INSTALLATION

1. Turn off the power to the Apple (check the power light to

insure that it is not on)

2. Remove the cover by pulling on the right and left rear

corners of the case, until both fasteners are released (popping

sound); slide the cover back until the front edge clears the lip

of the case, and lift up.

3. Find the desired slot. Slot number designations are printed

on the Apple’s main circuit board along the back edge near the

cutouts in the case. The leftmost slot is slot zero (closest to

the power supply, which is a long metal box).

4. Before touching any component or board in the Apple,

discharge any static charges, by touching the power supply cover

(long metal box at left side of Apple) immediately prior to

touching the component or card in the Apple.

5. Unpack the memory board. The memory board is packed in a bag

made of specially treated antistatic material to prevent damage

during shipment. It should be stored in this bag when not

installed in the Apple, or if transported outside the Apple.

6. Install the board in the desired slot:

A. Touch the power supply cover to discharge any static

charges.

B. Grasp the board at its edges and position over the slot.
