The Sprinter (also called Peters Plus Sprinter or PPS ) is a microcomputer made by the Russian firm Peters Plus, Ltd. It was the last ZX Spectrum clone produced in a factory.
It was built using what the company called a "Flex architecture", using an Altera PLD as part of the core logic. This allows the machine's hardware to be reconfigured on the fly for different ZX-Spectrum models compatibility or its own enhanced native mode (set by default on boot and running the Estex operating system).
