secondo test, ho ora collegato il c1541 con cavo x1541 da dos, ma non trova il drive come: 8,9,10,11
appena acceso si sente il disco che gira e si accende la luce rossa, poi nulla di più.
la cosa strana è che mi son visto i codici di errore del 1541, ma non è riportato l'errore DEVICE NOT PRESENT
ecco gli errori :
