Sinclair Cambridge Z88
The Cambridge Computer Z88 is an A4-size, lightweight, portable Z80-based computer with a built-in combined word processing-spreadsheet-database application called PipeDream (functionally equivalent to a 1987 BBC Micro ROM called Acornsoft View Professional), along with several other applications and utilities, such as a Z80-version of the BBC BASIC programming language.
The Z88 evolved from Sir Clive Sinclair's Pandora portable computer project which had been under development at Sinclair Research during the mid-1980s. The machine was launched at the Which Computer? Show on 17 February 1987.
