The Oscom Nano was manufactured by Oscom Oy in Finland release in 1980. The Nano is an improved version of the Telmac 1800. It did use the same CDP1864 video chip as the 2000 but as far as I could figure out did not have any colours. Instead it uses the 192 lines of the video chip for a resolution of 32 lines making every line consisting of 6 lines instead of 4 on the 1800 and 2000. Apparently this was more suitable for PAL TVs.
