The first drum scanners were developed by Hell since 1966. These scanners were not linked to a computer, since pictures could not yet be stored digitally. Available memory devices had not enough memory capacity, and they were too expensive and too slow. Only beginning in 1978, the first drum scanners could digitize pictures and store them in a computer.
