Unrivalled flexibility is the secret. It gives the Sanders Advanced Data Display System/900 the ability to meet nearly every display system need.

ADDS*/900 System interacts with analog, digital and operator input. Information is processed and formatted, then presented visually on up to 12 displays.

ADDS/900 System features a larger variety of display sizes and speeds than any other comparable system available today. High-speed vector, position and _character function generators permit unrivalled density of displayed graphics and alpha­numerics. ADDS/900 System offers rotation and translation of data, and exclusive graphic overlay on TV or radar video data.

Data entry devices having a common interface for standard 1/0 data transfer include Photopen®, trackball, joystick, keyboard, data tablet, and cursor control.

Sanders ADDS/900 System can solve your most demanding display problem. We've got the hardware, interfaces and software support. On the shelf. Whatever your data handling requirement -from microimage retrieval to a complete data management system---consider Sanders as your single source.

IBM demonstration of graphics in engineering and science

This IBM 1130/2250 Graphic Data Processing System was shown at Brunei University in April. Visitors were able to experiment with the light pen, using programs available from the system's Disk Storage.

The 1130/2250 is a powerful and direct method of man-machine communication. It gives designers, engineers and research scientists instant visual access to results of their computer programs. And the information presented is in an immediately usable form. Using the IBM Graphics Subroutine Package, you can easi Iy write your own programs. And with the latest Disk Monitor Operating System, now available, the full power and flexibilityofthis disk based graphics system is at your command.

The 1130/2250 can also be linked to IBM Systemj360 thus giving access to the facilities of Operating System/360. If you would like a leaflet and more information about the IBM 1130/2250, write to Mr. K. Parkes, IBM United Kingdom Limited, 389 Chiswick High Road, London W4. IBM
