CZ-2000

An Argentinian ZX Spectrum clone from Czerweny Electronica. The Issue 4 motherboard was imported from the Sinclair branch in Portugal. The RF-modulator was designed to produce colours according to the local PAL-N standard while genuine Sinclairs used PAL-B. This meant it was possible to use a standard Argentinian colour TV. It also gave a clearer picture ona B/W TV so it became very popular.

CZ-Spectrum

The Czerweny Spectrum replaced the CZ 2000 and it had adittions such as a reset button, two Sinclair compatible joystick connectors and video composite output in addition to the TV/RF modulator. It may have actually been a licenced clone as it used the Ferranti ULA.

CZ-Spectrum+

An updated verion of CZ-2000 launched in 1986. The case is designed to look like a ZX Spectrum+. The system messages in the ROM have been translated to Spanish and the motherboard is a ZX Spectrum issue 6 motherboard. The computer was designed and manufactured in Argentina, either in the Czerweny Patala plant or by local suppliers.
