Spectrum Inves +. A clone of the ZX Spectrum+ developed by Investrónica in Spain in 1986, based on the work developed by Investrónica for the ZX Spectrum 128. Released just after Amstrad bought Sinclair Research Ltd, looked much like a normal 48+, but all the inner parts were redesigned. As the ROM was also modified, it has compatibility problems with some games (Bombjack, Commando, Top Gun, etc.).[1] On the rear there was a Kempston joystick connector.
Due to the fact that Invéstronica was the distributor of Sinclair's products in Spain, and because Amstrad already had its own exclusive distributor in Spain (Indescomp, later bought by Amstrad itself), in 1987 Amstrad sued Investrónica to stop the sale of the computer.[2] The court agreed with Amstrad, but the decision was not issued until 1991, when the computer was discontinued as the 8-bit computer market in Spain was dead in favor of 16-bit computers.
