This is untested, I bought it a few years ago to display in my classroom. It came from a bid sale from a school that was being decommissioned, so it likely works, I just don't have a cable for it. It has a regular amount of yellowing, but it is missing one of the plastic latches on the lid, and one keycap. Could be a fun project for someone who is interested, I just don't have the space to store it anymore.
