Joe Ossanna worked diligently to see that WECo's ASCII teletype really would come to market and would meet the needs of Unix. He famously estimated that Bell Labs alone was a sizable market: 777 machines. He also leaned on WECo to make the return key issue a single newline. And he specified what non-ascii characters would fill out the 128 positions on the Bell Labs type boxes. This requires encoding 7-bit ASCII in 8 bits. I don't know whether WECo had been planning to do so anyway. Doug
