The Elektronika BK-0010 (Электроника БК-0010) was manufactured in 1985 and was the first in a series of home computers manufactured in Soviet Union. The computer was built based on a very successful DEC PDP-11 architecture and unlike the most home computers of that time (including computers made in the West) the BK-0010 had 16-bit microprocessor K1801WM1 (K1801BM1). The BK-0010 had a 32KB RAM half of which were dedicated to video and remaining 16KB were available to the user. 32 KB ROM contained BIOS and FOCAL interpreter. BASIC interpreter was also available as an add-on in an auxiliary module. The video was implemented on K1801WP1-037 (К1801ВП1-037) controller, which permitted 256x256 pixels with four colors or 512x256 pixels with two colors. Computer had an interface for a tape recorder for data storage with 1200 Baud speed, a serial RS-232 port with 50-9600 Baud speed, a video output for a connection to a TV and a QBUS connector. Thanks to the QBUS connector and a parallel port, a multitude of peripherals have been adapted or developed to be used with BK-0010 and BK-0011M: printers, mice, joysticks, sound devices, floppy and IDE controllers. The early BK-0010 model had a few hardware bugs and was soon replaced with BK-0011M.
