  1. I am really impressed with your blog.
    Anyway keep up the exellent quality writing!

  2. Buon giorno.ho visto tutto molto interessante..sono Daniele Bemporad di FIRENZE..Pisseggo da molti anni un EXECUTIVE 64….L’ho acceso per vederd se funziona..lo schermo e’ a posto ma il lettore interno dei floppy disk mi sa che non sia a posto..Sono un giovane nato nel 1948..quando i compiuter erano un sogno..quindi capirete la mia problematica..vorrei falo rifunzionare..mi dice. Disk error..ho provato von un nuovo disco per ruallineare la testina ma non trova nulla..MI SAPETE DIRE COME FARE..GRAZIE..non ho sito web..
