The VCB01 Video Controller is a quad-height, 22 bit QBUS bit-mapped display option module (DEC part number M7602), providing workstation capability for Q22-bus systems.
The bitmap memory (also called video memory), is 256 kB of MOS RAM, residing in the Q22-bus address space.
In the VAXstation I and VAXstation II, a subset (sometimes called the screen memory) of the bit-mapped video memory is displayed on a 48 cm (19 in) monochrome monitor (the VR100 Monochrome Monitor).
The VCB01 relies on the CPU to generate all images stored in video memory.
The VCB01 also provides several basic I/0 functions, including:
