commentsMany pre 1993 model M keyboards include a speaker grill on the rear case, but most model M keybaords do not have a speaker.  The 1394540 and 51G8572 keyboards includes the internal speaker that was originally useful in IBM RS/6000 computers.  Unknown how to make functional on a modern PC systems.
commentsThis keyboard is tested to work 100%. The keyboard assembly has been confirmed to be in functional, operational condition.
