This special spanish version was released by the spanish Amstrad distributor Indescomp without the knowledge of Amstrad UK. The additional 8 KB are only accessable from machine code. The spanish government had a tax for 64KB homecomputers which would have caused lots of costs for the mass sales of the CPC464. By adding 8KB Indescomp worked around this tax ...

In 1986 Amstrad took over Sinclair's computer business. Changes in the direction of Sinclair's most popular computer, the ZX Spectrum (released 1982 as sucessor of the popular ZX 81), were in the air.
In early 1987, the change came with the launch of the Spectrum +2. It was very different from any previous Spectrum, coming with a proper typewriter keyboard and built-in tape recorder and twin joystick ports. Externally at least, it was very similar to Amstrad's CPC 464.

The KC compact is a clone of the Schneider/Amstrad CPC 464, manufactured in the German Democratic Republic by RFT / VEB Microelektronik Muehlhausen. It was anounced to the 40. anniversary (7 Oct 1989) of the GDR, which lasted only a few weeks longer. So the KC compact was not produced very long and now is a rare collector's item. The CPU was a Z80-GDR-clone called UA880D. 64 KB RAM are equal to the CPC 464/664, the ROM is equal to the CPC 6128.
This KC computer is not compatible to the previous KC systems (i.e. the popular KC85/2-4 series), but it mainly is compatibly to the Amstrad CPC.
