Clones

This is my attempt at collecting information about the various clones of Sinclair machines that exists around the world. This is a tough task as there exists at least 20 different Spectrum clones in St.Petersburg alone! http://www.nvg.ntnu.no/sinclair/sst_spec.htm mentions "a legal problem in the Far East. Pirate Spectrums were flooding the market and the company was constructing a case that would enable it to sue for breach of copyright." I have however not found any of those.

Some (or all?) of 64K (or more) Russian clones can use the extra 16K as a shadow RAM. Some program are using it (for example PKUnZip for Speccy).

Some russian Spectrums use russian CPUs instead of the Z80. Some russian clones are T34V, KR1858VM1, KM1582VM2-0100 and VM3

T34V - developed and produced since 1991. White body with golden legs. Full analog of Z80A.
KR1858VM1 - Also full analog of Z80A.
KM1582VM2-0100 - made of plastic body, analog of Z80.
VM3 - logical not comparable with Z80.

On most of them (may be not on T34V) there was not any sign where they was made because of problems with license of manufacturing of these CPUs.
