The "MS" line was built by Minolta from 1960 to 1985. These dumbbell projectors exhibit various quality levels - the easy ones are school devices with 2500 star spots through precise projectors with 9000 stars for large domes. The model updates are chronologically numbered. MS-10 was the first projector sold to Europe. It was set up in Tampere, Finland, in 1969, but destroyed three years later because of a major fire. Later, it was substituted by a MS-15 (image). This version was permanently improved and reached a summit by being Minolta's most successful projector in the USA. It is customised to 14- to 17-meter domes. The first fully automated system was MS-18 presented in September 1978 in Tokyo. The series ended with MS-20 in 1980. The US company Viewlex sold the machines also under its own name.
