Sinclair ZX Spectrum+

Sinclair ZX · 1984

Sinclair's attempt to make the Spectrum look serious: an injected-moulded case with proper moulded keys, a reset button and a bigger footprint, wrapped round an unchanged 48K board. Widely disliked at the time for the keyboard's vagueness, but it is the same machine underneath and considerably nicer to type on than the rubber mat. The last Spectrum Sinclair designed before selling the company.
