Serial number of the original Speccy

Hello, kgbplus I'm not a collector, so I can't judge, but from the point of view of arithmetic, there is and other very rare models. For example, ZX Spectrum 128 which was released in England about 100 thousand, and in Spain even less (ZX Spectrum ISSUE 1 about 30 thousand). In addition, there are very rare ZX Spectrum series released by AB Electronics, and generally rare versions from Amstrad, for example +3 without a disk drive (Spanish version). It was not even possible to find photographs of this car (this one is alive Sergei Zhavoronkov saw the computer). About <16K only on ISSUE 1> this is a misconception. Up to ISSUE 4 were released computers with 16K (instead of additional RAM, the boards had sockets). You can distinguish the ZX Spectrum ISSUE 1 by the presence of a hole in the bottom of the computer. Yes and that is, the exception is ISSUE 2 from AB Electronics, but extremely rare.
