<h2 id="machines">Machines</h2> <h3>CZ 1000</h3> <p>Released in 1985, the CZ 1000 was a rebranded version of the <a href="/facts/Timex_Sinclair_1000/MgroVp9B">Timex Sinclair 1000</a>, itself a clone of the Sinclair <a href="/facts/ZX81/I0uDYb3n">ZX81</a>. This compact and minimalist machine came equipped with just 2 KB of RAM, making it an entry-level computer ideal for beginners and enthusiasts.<a class="footnote-ref" id="fnref:34" href="#fn:34"><sup>34</sup></a><a class="footnote-ref" id="fnref:35" href="#fn:35"><sup>35</sup></a><a class="footnote-ref" id="fnref:36" href="#fn:36"><sup>36</sup></a> </p> <h3>CZ 1500</h3> <p>Building on the CZ 1000, the CZ 1500 was a relabeled <a href="/facts/Timex_Sinclair_1000/MgroVp9B">Timex Sinclair 1500</a>, which offered an upgraded 16 KB of RAM. It maintained the simple design of the <a href="/facts/ZX81/I0uDYb3n">ZX81</a> while providing the additional memory needed for more complex applications and programs.<a class="footnote-ref" id="fnref:37" href="#fn:37"><sup>37</sup></a><a class="footnote-ref" id="fnref:38" href="#fn:38"><sup>38</sup></a><a class="footnote-ref" id="fnref:39" href="#fn:39"><sup>39</sup></a> </p> <h3>CZ 2000</h3> <p>The CZ 2000 represented a significant evolution, as it was a <a href="/facts/ZX_Spectrum/JVbaDHrU">ZX Spectrum</a> clone. It featured the black casing of the CZ 1500 but included a ZX Spectrum rainbow logo, signaling its compatibility with the popular machine.<a class="footnote-ref" id="fnref:40" href="#fn:40"><sup>40</sup></a><a class="footnote-ref" id="fnref:41" href="#fn:41"><sup>41</sup></a> This marked Czerweny’s move towards more advanced computing capabilities, including improved graphics and sound. </p> <h3>CZ 1000 plus</h3> <p>Introduced in 1986, the CZ 1000 plus introduced key enhancements to the original CZ 1000. It adopted a new case with a design similar to the ZX Spectrum, featuring <a href="/facts/Chiclet_keyboard/KeYf4TJP">rubber keys</a>, along with two joystick ports, <a href="/facts/Composite_video/FIsE6mBz">composite monitor output</a> for clearer video, and a reset button.<a class="footnote-ref" id="fnref:42" href="#fn:42"><sup>42</sup></a><a class="footnote-ref" id="fnref:43" href="#fn:43"><sup>43</sup></a><a class="footnote-ref" id="fnref:44" href="#fn:44"><sup>44</sup></a><a class="footnote-ref" id="fnref:45" href="#fn:45"><sup>45</sup></a> These improvements made it more appealing for gaming and advanced use, offering a more modern computing experience. </p> <h3>CZ 1500 plus</h3> <p>Also introduced in 1986, the CZ 1500 plus upgraded the CZ 1500 with the same suite of enhancements found in the CZ 1000 Plus.<a class="footnote-ref" id="fnref:46" href="#fn:46"><sup>46</sup></a><a class="footnote-ref" id="fnref:47" href="#fn:47"><sup>47</sup></a> </p> <h3>CZ Spectrum</h3> <p>Introduced in 1986, the CZ Spectrum was essentially a CZ 2000 in a larger case that incorporated the enhancements introduced with the CZ 1000 Plus. It maintained ZX Spectrum compatibility while offering a more robust design featuring rubber keys, joystick port, and a reset button.<a class="footnote-ref" id="fnref:48" href="#fn:48"><sup>48</sup></a><a class="footnote-ref" id="fnref:49" href="#fn:49"><sup>49</sup></a> </p> <h3>CZ Spectrum plus</h3> <p>Introduced in 1987, the CZ Spectrum plus was a refined version of the Sinclair ZX Spectrum, housed in a <a href="/facts/ZX_Spectrum/JVbaDHrU">Spectrum+</a> style case. This model included joystick ports, composite monitor output, and a reset button, but it also featured a unique local adaptation: the <a href="/facts/Sinclair_BASIC/NCnAcdR3">Sinclair BASIC</a> messages were translated into <a href="/facts/Spanish_language/95BgYNfv">Spanish</a>, making the system more accessible and user-friendly for the Argentinian market.<a class="footnote-ref" id="fnref:50" href="#fn:50"><sup>50</sup></a><a class="footnote-ref" id="fnref:51" href="#fn:51"><sup>51</sup></a> </p> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"Tadeo Czerweny History".
