More Sinclair clones were produced in the former Soviet Union than in the rest of the world put together. Although clones were manufactured in several of the former Soviet republics, the Russians were by far the largest users and developers of cloned Sinclair computers. In many cases, the machines were designed and built by electronics enthusiasts reverse-engineering smuggled-in computers. A complicating factor for the Russians was the difference in alphabets; consequently, many Russian Sinclair clones were built with support for both Roman and Cyrillic characters. Many Russians are still, to this day, keen Sinclair users, although inevitably the PC is becoming predominant.
