> the original Apple Computer (later called the Apple I)
All the original manuals/ads/etc (that I can find online) called it the Apple-1 (Arabic, not Roman). I think Woz was already working on the Apple II by the time the Apple I was released.
Author here. Yes I could be more accurate here. It was called just "Apple Computer" in some contexts, e.g. this ad [0]. This manual calls it "Apple-1" on the cover [1], but "Apple Computer" in the contents. But you are definitely right that it was often called the Apple-1 in 1976 and into 1977.
