Telmac TMC-600

The Telmac TMC-600 was a Finnish microcomputer introduced in 1982 by Telercas Oy, a Finnish importer of RCA microchips.

Only 600 units were produced, making it very rare today. The TMC-600 was the only commercially available BASIC-based home computer designed and manufactured in Finland.
