<I bet it made some of the Big Blue types sick! Why? There was a version of the selectric design and used as a keyboard printer. I've seen them on tandy, NS* and others with both serial and parallel ports. Duratec was one company selling them configured that way. The serial ones used 134.5baud! Not only did they print well and reliably they had different typeballs. As printers went they were fairly quiet too. Allison
