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.
A one hour lasting training course about scanner technology is available on DVD. Please consider about a donation and contact us by the contact form.
