[Blindtlk] A refreshable Braille display-related idea

[Julie J.]

I've seen Braille displays with multiple lines.  I'm remembering four, 
but it could have been six.  That was several years ago though and I 
don't know how old the product was.  Are these not made anymore?

The multi line Braille display I saw was designed for a desktop computer 
and was not meant to be easily portable.  Maybe folks here are 
specifically referring to a portable Braille display?  I haven't read 
every message on this topic.
