WULA 81<\/strong> es una ULA (Uncommitted Logic Array) de reemplazo para ZX81 y Sinclair. Si tu ZX81 no muestra imagen o tiene fallos de v\u00eddeo intermitentes, el WULA 81 soluciona el problema con un chip nuevo que reproduce exactamente la funci\u00f3n de la ULA original.<\/p>\n

Compatibilidad<\/h2>\n
    \n
  • ZX81 original Sinclair<\/li>\n
  • Timex 1000 y Timex 1500<\/li>\n
  • Wilco81 y clones ZX81<\/li>\n
  • Cualquier ZX81 que use la ULA est\u00e1ndar de 40 pines<\/li>\n<\/ul>\n

    C\u00f3mo usarlo<\/h2>\n
      \n
    1. Retira la ULA original de tu ZX81 con cuidado usando un extractor de IC<\/li>\n
    2. Inserta el WULA 81 en el z\u00f3calo, alineando la muesca con la del z\u00f3calo<\/li>\n
    3. Verifica que todos los pines est\u00e1n correctamente inseridos<\/li>\n
    4. Enciende el ZX81 y comprueba que la imagen aparece correctamente<\/li>\n
    5. Si la pantalla muestra el cursor parpadeando, el WULA 81 funciona perfectamente<\/li>\n<\/ol>\n

      Incluido<\/h2>\n
        \n
      • 1x WULA 81 (chip ULA de reemplazo)<\/li>\n<\/ul>\n

        Diagn\u00f3stico:<\/strong> Si tu ZX81 muestra pantalla en blanco, negra con rayas, o imagen intermitente, probablemente la ULA est\u00e1 da\u00f1ada. El WULA 81 es la soluci\u00f3n directa sin necesidad de buscar chips vintage en mercados de segunda mano.<\/p>\n

        Consejo:<\/strong> Antes de reemplazar la ULA, verifica que el problema no est\u00e9 en la conexi\u00f3n del cable de v\u00eddeo o en la fuente de alimentaci\u00f3n. Una ULA da\u00f1ada es la causa m\u00e1s com\u00fan de fallos de v\u00eddeo en ZX81 antiguos.<\/p>\n","protected":false},"excerpt":{"rendered":"
