Pentagon (computer)
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 the shape of the original Pentagon 48 PCB which has a diagonal cut in one of the corners, giving it five sides.
The Pentagon 1024SL v2.3 included most of the upgrades of the standard Spectrum architecture, including 1024 KB RAM, Beta 128 Disk Interface and ZX-BUS slots (especially for IDE and General Sound cards). This model also featured a "turbo" mode (7 MHz instead of the original's 3.50 MHz).
