Developed as part of the plus range, the GX4000 was Amstrad's short-lived attempt to enter the video game consoles market. Sharing the plus range's enhanced hardware characteristics, it represents the bare minimum variant of the range without a keyboard or support for mass storage devices. It came bundled with 2 paddle controllers and the racing game Burnin' Rubber. Special models and clones CPC472 During the August holidays of 1985, Spain briefly introduced an import tax of 15 000 pesetas () on computers containing 64 KB or less of RAM (Royal Decree 1215/1985 and 1558/1985), and a new law (Royal Decree 1250/1985) mandated that all computers sold in Spain must have a Spanish keyboard. To circumvent this, Amstrad's Spanish distributor Indescomp (later to become Amstrad Spain) created and distributed the CPC472, a modified version of the CPC464. Its main differences are a small additional daughter board containing a CPC664 ROM chip and an 8 KB memory chip, and a keyboard with a ñ key (although some of them were temporarily manufactured without the ñ key). The sole purpose of the 8 KB memory chip (which is not electrically connected to the machine, so consequently rendered unusable) is to increase the machine's total memory specs to 72 KB in order to circumvent the import tax. Some months later, Spain joined the European Communities by the Treaty of Accession 1985 and the import tax was suppressed, so Amstrad added the ñ key for the 464 and production of the CPC472 was discontinued. KC compact The ("" - which means "small computer" - being a rather literal German translation of the English "microcomputer") is an unofficial clone of the Amstrad CPC built by East Germany's in October 1989. Although the machine included various substitutes and emulations of an Amstrad CPC's hardware, the machine is largely compatible with Amstrad CPC software. It is equipped with 64 KB memory and a CPC6128's firmware customized to the modified hardware, including an unmodified copy of Locomotive BASIC 1.1. The expansion port is a K 1520 bus slot. The KC compact is the last 8-bit computer produced in East Germany. Due to the German reunification happening at the time of the release only a very small number of systems were sold. Aleste 520EX In 1993, Omsk, Russia based company Patisonic released the Aleste 520EX, a computer highly compatible with the Amstrad CPC6128. It could also be switched into an
