At first glance, the CZ Spectrum Plus looks like a Spanish ZX Spectrum+.  But it’s actually much narrower than a ZX Spectrum+ because the dimensions of the case bottom are similar to that of the CZ Spectrum and all CZ Plus models. In the box were optional legs to raise the machine a bit, similar to those shipped with the Sinclair QL.

It shares its ROM with the Inves Spectrum+ (Spanish error messages and no Sinclair copyright on the boot screen). It also features two built-in joystick ports (DIN-6), hardwired to the keyboard. They are compatible with ZX Interface 2 (67890 / 12345).
