Sony occasionally repurposed the Walkman cassette mechanisms for devices like this impressive do-it-all travel companion for the international (walk)man of mystery. Suitable for carrying in a briefcase, recording meetings and voice memos, working as an alarm clock, catching up on news from back home and listening to stereo music cassettes on the plane. UPDATE: I noticed in the closeups that a few parts of the Walkman needed another clean - so after the video was edited I’ve gone back and done this. Specifically there’s a bit of belt residue that you can see on the tape door in some shots. That stuff gets everywhere - you’ll also see it on my fingers in the review of the 40th Anniversary Walkman.
