Guido: I've been researching about Kurzweil and there is a Kurzweil 3000 in addition to 1000, what is the difference between the two of them?? Does the people at Kurzweil give the minimum requirements your computer must have in order to operate the program??? Also ,I've been in oblivion following your discussions about Kurzweil,Braille, Reading Edge and the famous Optacon; is Kurweil a software alone or it includes a machine and everything? About Reading Edge I've picked up the idea, but with the Optacon how does it works?? I have a sight ailment but I see thanks to a very thick glasses I use above my nose, but I would like to be a Braille literate, how could I do it??? Very truly yours, Dilsia, whose knowledge of a world without light is scarce
