Create a 3D model of a vintage 1980s cash register. The register should have a bulky, metallic body with a matte black finish, typical of the era. Include large, mechanical buttons with numbers and basic function keys, as well as a raised display for prices. The cash drawer should have a chrome handle and slightly worn edges. Add a paper receipt roll visible at the top. The register should have an analog feel, with simple, clear labeling and a retro design, evoking the 80s retail atmosphere.
