A video terminal includes the deflection, power supply, video, and synchronization circuits of a commercial, home television receiver. The deflection yoke of the receiver is rotated through 90 DEG to provide fast vertical rather than fast horizontal sweeps. The fast sweep frequency is approximately doubled to improve resolution along the rows of the characters displayed. The bandwidth of the receiver is increased to improve resolution in the fast sweep direction. The fast sweep retrace period, the slow sweep retrace period, and the frame repetition period of the receiver are not changed. |
