Elektronika BK

The Electronika BK is a series of 16-bit PDP-11-compatible home computers developed under the Electronika brand by NPO Scientific Center, then the leading microcomputer design team in the Soviet Union. It is also the predecessor of the more powerful UKNC and DVK micros. This machine features a 16-bit K1801VM1 CPU, compatible with DEC's LSI-11 line. It has onboard DRAM, video memory, and supports two graphic video modes. Sound is initially basic but can be enhanced with an AY-3-8910 chip. It also includes a universal parallel port for peripherals and can have a floppy drive controller added. BK-0010 is the first model (originally released in 1983, the serial production since 1985). It has a full-travel keyboard, 32 KiB RAM, 8 KiB ROM with BIOS (chip K1801RE2-017), 8 KiB ROM with FOCAL interpreter (K1801RE2-018), 8 KiB ROM with debugger (K1801RE2-019) and a conventional and a Vilnius BASIC p-code compiler in the ROM; its CPU is clocked at 3 MHz. A tape recorder is used for data storage in the factory configuration.
