The 12065A has been designed to specifically address the needs of the computer-aided manufacturing marketplace. This video interface offers medium resolution, as well as some unique display features that will dramatically increase your productivity. The card utilizes a Motorola 68008 16-bit microprocessor for system control and backplane communications. It also provides supervisory control over a specialized graphics processor, pixel memory and video circuits. Four pixel memory planes provide for two combinations of color and character capability. In one mode, three pixel memory planes are used to produce 8 colors from a palette of 4096 leaving the fourth plane for overlay of characters, cursors, and prompts. In the second color mode, all four planes are used to produce 16 colors from a palette of 4096. In both modes, independent blink control of each color is possible on-card. A standard character set is provided in ROM with user-specified size and orientation for maximum flexibility. In addition, the card will support user-defined characters, for example, foreign languages which can be downloaded to local RAM from the A-Series CPU. Benefits of the on-card intelligence and the DMA per I/O card A-Series architecture result in flexible drawing capabilities. In an Update mode, an existing screen is added to, either with characters or vectors, with immediate display of results. This is the mode you would use to change data or to perform limited animation, such as increasing or decreasing tank levels in a process control flow application. Using the Frame Buffer Read/Write capability, entire screens can be downloaded via DMA to pixel display memory (frame buffer) and then to the screen. The whole screen image is displayed within seconds. This feature is particularly useful in applications where several displays are used frequently as operators execute sequences of control or trackdown process problems tagged with alarms. Frame Buffer Reads/Writes automatically take advantage of flash-fill, where data is written to display memory while the screen is continuously blanked. The screen is then unblanked to display the image. Update mode can also be configured for flash-fill to take advantage of the higher performance realized. [Figure 1 (charts) Caption: Screen Blanked, 60 Hertz Refresh Rate, 50 Hertz Refresh Rate, Alphanumeric Overlay and Graphic Characters] In general, display images used frequently will be initially created in Update mode. Once in frame buffer memory, the image will be stored in A-Series memory, or on disk, via Frame Buffer Reads. Later, the A-Series can redisplay the image using Frame Buffer Writes; additional modifications can be made in Update mode. Finally, the 12065A also supports two RS-232-C serial ports to allow for the direct attachment of graphics input accessories. This allows devices like custom keyboards and keypads, touch screens, trackballs, joy sticks, or mice to be interfaced through one graphics sub-system. This saves money and I/O slots.
