The Investronica V9 is an 8-bit personal computer released in 1984 by the Spanish company Investronica . It is most famous for being a direct clone of the Sinclair ZX Spectrum (specifically the 48K model), but with significant hardware and design improvements that made it a superior machine in many ways.
