摘要：
A logic control system for a video display terminal is disclosed for accommodating vertically and horizontally varying entry points to a video memory to acquire first character bytes of rows of video information for display on a CRT screen. Dynamically changeable display page snapshots of the video memory, and the formation of display pages from randomly located rows of video information within the video memory are thereby provided.
