The Back Slot equipment choice in the early days of the game was quite simple: a cloak or nothing. While the pre-Age of Shadows, charge-based item properties applied to cloaks, other than that they were worn for looks.
Quivers did not exist until the Ultima Online: Mondain's Legacy expansion in 2005. Prior to their introduction, Archers simply carried ammunition in their Backpack. At one point, the UO development team refered to the inclusion of quivers a mistake. At the time, they argued that they made archers too powerful. Archers were subsequently nerfed, but we got to keep quivers.
