Hi List, Could we, as a group, approach engineering departments who might be interested in working on a modern version of the Optacon?

The realm of possibilities for such a device is truly exciting.-Ninette LeGates to view the list archives, go to: www.freelists.org/archives/optacon-l To unsubscribe at any time, just send a message to: optacon-l-request@xxxxxxxxxxxxx with the word "unsubscribe" (without the quotes) in the message subject.
