Pentagon (computer): Products, Versions & Overview

The Pentagon (Russian: Пентагон) home computer is an enhanced clone of the British-made Sinclair ZX Spectrum 128. It was manufactured by amateurs in the former Soviet Union, following freely distributable documentation. Its PCB was copied all over the ex-USSR between 1991-1996, making it a widespread ZX Spectrum clone. The name "Pentagon" derives from…
