[net.micro] Anyone heard of Tech Vision?

PHORWITZ@BBNG.ARPA (10/05/85)

My mother, who is visually impaired, has been told of a company
named Tech Vision (or possibly Vision Tech?)  that makes a
peripheral for IBM or Apple (II, Macintosh?)  consisting, from
her description, of a large monitor and accompanying
software/hardware to enable one to zoom in on a particular
section of text.  Sounded as though this thing was compatible
with whatever word processor software would run on the vanilla
machine.  Does anyone out there know what I am talking about?  If
so, could you tell me??

Thanks.
