Yep 1977, part of the first ever generation of home games consoles, so intentionally blind accessible console gaming has been around for pretty much as long as games consoles have. It's called the Games Center, and it was made by TSI, the same people who made Optacon and various other blind accessibility devices in the 70s and 80s.
If anyone's anywhere near Louisville Kentucky, the APH (The American Printing House for the Blind) museum owns one of them.
