The Pentagon (Пентагон) home computer, manufactured in former Soviet Union, is a clone of the British-made Sinclair ZX Spectrum 128. Its PCB was copied all over the USSR, which made it the most widespread Soviet ZX Spectrum clone. Later models featured a "turbo" mode that allowed for higher processor speed than the original's 3.50 MHz.
The latest model is Pentagon 1024SL v2.3, which includes most of the upgrades of standard Spectrum architecture, including 1024 KiB RAM, Beta Disk Interface and ZX-BUS slots (especially for IDE and General Sound cards).
