What will I receive after ordering?

How do I fit the EPROM chips?

Switch off and open up your device and note the orientation of the original EPROM(s). There is a notch at one end. Gently remove the original EPROM(s) using a lever or screwdriver to lever the EPROM from its socket. Place the new London EPROM in the socket and gently insert.
