Remove old EPROM by using adequate tools
only, e.g. EPROM extractor supplied by RS
Components - part. no. 404-727 or F.A. Sening
Part No. 7351002.
Place both claws of the extractor into the
socket, press EPROM extractor slightly against
the socket and push the legs of the EPROM
extractor with your thumb and index finger (see
picture). By means of the self-acting leverage effect the EPROM will then
be pulled out automatically.
