Abstract
A personal computer having an interactive all points addressable display thermal (44) and a cursor positioning device (52) is provided with apparatus for facilitating the generation of a graphics display. At least one table of selectable cursor characters is stored in memory (16), and from this table, any character can be selected to be the cursor character. The selected character is displayed as the cursor and movable to any point on the all points addressable display by the cursor positioning device. Once the current cursor character is at a desired point on the display, it is fixed in that position by reading the position and cursor data into the display buffer of the display terminal.
