Cambridge Z88 debuts
From an article published in Sinclair User in April, 1987: “A portable computer has long been one of Clive Sinclair's most cherised ambitions. … And now here's the Z88. Unveiled at the Which Computer? Show on February 17 to muted wonderment, this 21 pound, A4-sized technogimmick is in the best Sinclair traditions. It's black. It's cheap. And it's not finished.” Wikipedia has more details and less snark.
