What means
It was a screen graphic in Ohio Scientific's character set.
Unicode's compatibility proposal maps it to Ohio Scientific code 03 and dates those computers from the mid-1970s to mid-1980s. Its role shifted from screen art to character data modern software can use to reproduce those old displays.
