What about the first to use a slot inventory at all? In 1984 "Sundog: Frozen Legacy", first on the Apple ][e then on the Atari ST is the earliest example I remember of a game with a slot inventory. You couldn't yet put something "twice the size", using two blocks but you could already move inventory from character to your vehicle or to your spaceship's cargo. https://en.wikipedia.org/wiki/SunDog:_Frozen_Legacy https://en.wikipedia.org/wiki/SunDog:_Frozen_Legacy This game was made by FTL. They then later on made "Dungeon Master".
