Overview Russian ZX spectrum clone. Dated 1991. Unfortunately doen’t works. I order this computer without PSU or video wires. It use DIN5 for power connector. I assume it should powered by 5V DC. I solder wire with DIN5 on one side and USB A on another side. For power source I take USD PSA with 2A. For video i order wire with DIN5-SCART connector with external power. Restoring not on the way...
