year 1984

The Sinclair QL, QL for Quantum Leap, was a personal computer launched by Sinclair Research in January 1984, as the successor to the ZX Spectrum. The QL used a Motorola 68008 processor clocked at 7.5 MHz, came with 128 KB of RAM and could be connected to a monitor or TV for display. It used a multitasking operating system (OS), Sinclair QDOS, primarily designed by Tony Tebby, and was bundled with an office suite (word processor, spreadsheet, database, and graphics) written by Psion. It had a built-in advanced BASIC Interpreter named SuperBasic designed by Jan Jones. Physically, the QL resembled the contemporary ZX Spectrum+, including its non-standard plastic keyboard.The QL was the second 680XX-based personal computer to be released, following the Apple Lisa but beating the Apple Macintosh by a month, and the Atari ST by several.
