I look forward to hearing back from everyone's experience.  I just
made a minor, but important update, for when you read a screen block
that doesn't yet exist as a block file on the CFFA1 filesystem.
Previously there would be an error message, now you just get a blank
screen that will be properly updated when altered.  Over time, we can
create a nice library of words for the Apple I.
