The original GEM S Series included the S2 and S3.
This was extended to the GEM S Turbo series and included the GEM S2 Turbo, GEM S3 Turbo and GEM S2/R (Rack with Turbo by default). The GEM S4 was not released as a production model.
Due to the interest from owners of the original S Series (non-Turbo), a TurboKit (Hardware and software expansion), was released in March 1994.
