Telmac 1800 "Hobby computer" was designed 1977 and became a success. A bit later, 1980, the designer of Telmac (Osmo Kainulainen) made a new improved design he called OSCOM Nano (anyone knows how Telmac 2000 relates?). It was sold (by Oscom Oy) ready built and fixed a number of problems with Telmac 1800, but was targeted not only to hobby users but also to industrial use.

Price for Nano (at 1980) was 990mk (NMOS version with 4k RAM).
