combination of the modes just described.
WP (Memory Module): WP (write protect) works like the write protect on a floppy disk, that is, when it is
in the protect position, writes to the media cannot be made. When a floppy disk is in use, the write
protect is not physically accessible. Unfortunately (and for the following reason only), the WP
switch on the Memory Module is physically accessible when it is in use. If the WP is switched
while data is being transferred, non-transfer of all data or data corruption will result. The
WP may, however, be switched while the memory module is powered and not having data
transferred.
