The Atari Lynx being the first repair is a great choice — that thing was
famously enormous and ate batteries like nothing else, so it feels right that
it would be the one sitting on the workbench first.

Does the game model actual failure modes, or is it more abstract? I am curious
whether it gets into things like leaking capacitors and corroded battery
contacts, since that is what actually kills most hardware from that era, or
whether it keeps the repairs simpler for the sake of the chill pacing.
