Figure 3. Locating and Removing the EPROM
Caution:
Take care not to damage any pins when removing or installing chips.
2. Insert the new EPROM into the socket on the board. Chip pins may need to
be adjusted to fit into the socket. Use the following steps to adjust the pins:
• Lay the chip on its side with the pins facing away from you.
• Gently rock the chip away from you to bend the pins.
• Lay chip on its other side and rock it away from you.
• Repeat the above steps, alternating sides of the chip, until pins are at
approximately a 90-degree angle and line up in the socket.
3. The notched end of the chip goes up. There is a silk-screened image on the
CPU board you can use to line up the notch correctly. This image is labeled
EPROM.
4. Push the EPROM chip in gently. Do not force it, as you may cause damage
to the chip or the CPU board.
5. Replace the protective plastic cover over the CPU board.
