Color Video Output Interface, Technical Data
For HP 1000 A-Series Computer Systems
Product Number 12065A
The HP 12065A is a plug-in interface card providing full-color video
output capability for the HP 1000 A-Series family of real-time
computers.
Features
o Graphics/1000-II Version 2.0 compatible
o Red-Green-Blue (RGB) RS-343 compatible video output
o 512 x 512 pixel resolution for 1:1 aspect ratio displays
o 576 x 455 pixel resolution for 4:3 aspect ratio displays
o 16 colors selected from a palette of 4096
o Alphanumeric text overlay
o On-card, independent blink control of each color
o Polygon area fill
o Scrolling capability
o Two RS-232-C ports for keyboards, touch screens, and mice
Functional Description
The 12065A Video Output Interface provides full-color video output
capability to color displays for the HP 1000 A-Series family of computer
products. 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.

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.
