Czerweny CZ 1000

CZ 1000 is a rebranded Timex Sinclair 1000 assembled for the Argentinian market by Timex of Portugal in 1985.

Czerweny later upgraded it to the CZ 1000 Plus with the new casing, rubber keyboard, new PCB design, video composite out, reset switch, and 1 joystick port. The new casing was shared between the CZ 1000 Plus, the CZ 1500 Plus, and CZ Spectrum. Some rubber keyboards were bought from Microdigital (darker keys used on TK85) and some from Timex of Portugal (gray keys) as well other components.

Czerweny also imported the Timex Sinclair 1016 16K RAM Pack and rebranded it as the CZ 1016.
