TADEO CZERWENY "CZ" is a an electromechanical company, which was founded by Tadeo Czerweny in September 1958. It is located in Parana, Entre Rios province, in Argentina. The company made transformers, electric motors, etc. In the 80´s Czerweny marketed the Timex Sinclair´s models, under its own name.
In Argentina Czerweny models competed with Brazilians TK 83, 85, 90x and genuine Sinclair machines, but CZ sold more machines than them.
Marcelo Garcia comments:
In the 80's in Argentina it was possible to find a memory expansion module (16 KB), which was simply a box with extra memory chips which plugged into the back of the Czerweny CZ 1000
