The OREL BK-08 is a personal computer produced in Dnipropetrovsk, Ukraine, and fully compatible with the ZX Spectrum. Built around a Z80A-compatible processor, it featured 64KB RAM, a Russian/English keyboard, joystick ports, and a cassette interface. Its most unusual feature is a shadow RAM system with a built-in machine code monitor, activated via a dedicated NMI button—ideal for debugging. The machine booted into a localized BASIC system with Cyrillic support. Despite only partial compatibility with ZX Spectrum software, the BK-08 remains a fascinating example of post-Soviet computing.
