Komputer 2086

The Unipolbrit Komputer 2086 was a Polish version of the home computer Timex Sinclair 2068,      produced by a joint venture of the Polish state-owned Unimor and foreign company Polbrit International. Introduced in 1986, the computer had a cost of roughly 190000 zł.

The machine wasn't 100% ZX Spectrum-compatible (like all other Timex Sinclair computers) and a "Spectrum Emulation" cartridge was available (usually bundled).
