Step 5
Use a chip extractor to remove the first EPROM from its socket. If you do not have a chip
extractor available, use the tip of a screwdriver blade to gently pry the EPROM out of its
socket.
Step 6 Install the new EPROM in the same numbered socket as old EPROM you just removed.
Observe the correct notch orientation for the new EPROM.
Step 7 Repeat Steps 5 and 6 until all new EPROMs are installed. Be careful not to bend or break
any of the pins. Use needlenose pliers to straighten a bent pin. If a pin breaks, you must
obtain a replacement.
