The facilities available include display of points, lines and characters under control of digital instructions successively called from computer memory, and an alphanumeric and a function key board for user communication with the program. The function keyboard may be used in connection with a light-pen to enter and manipulate graphic information. Graphic display.-The control words (of 16 bits each) are called up in sequence. Each word specifies x and/or y co-ordinates either in absolute form or relative to the last addressed spot position, and control the beam unblanking as required. For character display the centre-point is addressed first, and then signals ordering the spot deflection to write the character are decoded to energize independent deflection coils. Light pen.-This is a fibre-optic device and includes a switch operated when the tip is pressed against the screen. The pen is operative to draw lines etc., and/or pass positional information to memory, only in certain modes of operation. Keyboards.-In addition to the alphanumeric keyboard, a programmed function keyboard is provided which is pre-set by the use of an overlay for the keys carrying punchings to enable the keys to function appropriately to the particular overlay designations. Multiple display units.-A number of display units may be controlled by the program, which allows selection of units for display. Long and short persistence display.-Data for display by the long persistence phosphor layer (so-called "static" display) is specified as such by the control words and regeneration of this for one of (say) thirty-two consoles by the program controls is followed by programmed regeneration of the short-persistence (or "dynamic" display) layers of all consoles. Program details, including subroutine jumps for character display etc., interrupts resulting from pen signals, etc. are set out in the Specification, which also gives schematic layouts of the logic circuitry.
