The Cambridge Z88 is a Z80-based notebook computer released in 1987 by Cambridge Computer, the company formed for such purpose by Clive Sinclair. It was approximately A4 paper sized and lightweight at 0.9 kg (2.0 lb), running on four AA batteries for 20 hours of use.

The Z80 is an 8-bit microprocessor introduced by Zilog as the startup company's first product. The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975, before going on sale in July 1976. The processor is a software-compatible with the Intel 8080 but with several enhancements and at a lower price. Like the 8080, the Z80 was mainly aimed at embedded systems, but it became one of the most widely used CPUs in home computers of the late 1970s and early 1980s. The Zilog Z80 was also common in military applications, musical equipment, and coin-operated arcade games of the era, including Pac-Man.
