Vintage Soviet Russian USSR ISKRA 210 VFD Tubes Calculator 1977 For Repair. You see I had no original AC cable to connect it to 220V AC outlet. So I soldered another one directly to feed calculator. It powers up and somehow works, but I am not sure...for me it works erratically. Probably one VFD bulb is missing (the fourth from right side). Has crack on the corner near power switch. Buttons 3 and = are sticky and won't come up. All parts are original and nothing added, just power plug for inspection.. I have no time anymore for repairs because so much more items are upcoming. . Collectable item for repair or display unit. Will be shipped from Europe by Air Mail International priority mail. Thanks for looking I will ship Worldwide. PayPal only. No returns. ATTENTION!!! The same shipping price to Worldwide. Please don't forget to add US shipping rate as in description if You in different country...
