Cambridge Computer Ltd was formed by Sir Clive Sinclair after Amstrad acquired Sinclair Research's computer business in 1986. Its principal product was the Z88, a compact battery-powered computer launched in 1987 and designed for genuinely portable work.
The A4-sized Z88 combined a silent membrane keyboard, wide LCD, solid-state storage and a multitasking operating system called OZ. Built-in PipeDream software provided word processing, spreadsheet and database functions, while expansion cards supplied extra memory and removable storage. The machine was modestly successful but became an influential example of the lightweight notebook computer.
