Certainly the head moved on most if not all ball/cylinder/wheel devices. Look at the Selectrics, Teletype 33, the Diablo/Xerox/Qume terminals, as common examples.
- bregma 1y agoI have never seen a Selectric in which the ball moved instead of the carriage. I can't imagine how complicated the mechanics would be for that and how often it would jam, break, or malfunction. Certainly not something a company such as IBM would make their reputation on. I used many Selectrics in my time.
- kps 1y agoYou must be confusing these with something else. Every Selectric had a fixed carriage and moving head.
