Build itChecked Jul 27, 2026	Radio-86RK remakeby Sergey Kiselev complete system sram composite video cassette serial parallel io open hardware replica	Recreates the 1986 Soviet Radio-86RK home computer on one board with an Intel 8080A, 32 KB of SRAM, integrated keyboard, monochrome composite video, cassette, serial, and parallel interfaces. For this compatible system (exact system): This is the complete mainboard and keyboard design for Sergey's Radio-86RK remake. Supply all components, programmed monitor and font ROMs, a suitable regulated power source, and a display accepting 50 Hz monochrome composite video. Many NTSC displays may work but can shift or crop the picture. The optional ROM-cartridge boards still require their own components and programmed images. The GPL-3.0 repository provides Version 1.4 KiCad files, Gerbers, a bill of materials, monitor and font ROM images, project notes, and archived original magazine material. Weird Electronics' bare-PCB listing was temporarily unavailable while the seller takes a break through August 20, 2026; when active, it includes only the main PCB and two ROM-cartridge PCBs. This is a large through-hole build requiring several vintage Intel 8xxx or compatible chips, 67 key switches, programmed ROMs, and regulated power. The Tindie heading incorrectly calls it an Intel 8088 computer; its own detailed specifications and the project repository correctly identify an Intel 8080A.
