It contains a 7X11X128 character generator ROM, a wide graphics mode, a thin graphics mode, an external input mode, character address/data latch, field and/or character attribute logic, attribute latch, four cursor modes, two programmable blink rates, and a high speed video shift register. The CRT 8002H VDAC is a panion chip to SMC's CRT 5027/37 VTAC®. Together these two chips prise the circuitry required for the display portion of a CRT video terminal. The CRT 8002H video output may be connected directly to a CRT monitor video input. The CRT 5027/37 blanking output can be connected directly...
