The Wersi Entertainer was a portable single keyboard organ designed as a starter instrument or for use while traveling.
It could be operated from standard house current as well as 12 VDC. The tone generation system was based on a single chip (ITT SAA-1900) designed to scan the keyboard and
produce 3 polyphonic outputs (solo 8', solo 16' and chords) and single monophonic
output (bass).
