It's unclear to me if it was ZX-Spectrum compatible, seems like it wasn't. Which would have severely limited it's usability. ZX-Spectrum clones were as pervasive as mushrooms after rain in Eastern Europe, Romania had 5 different "brands" of them. There were also attempts at producing proprietary, non-ZX spectrum compatible, Z80 based computers. They were short lived and failed in the market, like this weirdness: https://retroit.ro/product/amic/ https://retroit.ro/product/amic/ Overall if it didn't run Spectrum games it was fairly useless.
