 ====== Image Engineering Digital Video Decoder DVD-283 ======
+Information here is based on research and logical guesses.
+- This unit decodes digital data modulated in a video signal to DACs that drive laser projectors.
+- This unit doesn't appear to have a CPU. The incoming data seems to clock the hardware and the data to the DACs.
+- The unit supports two scan heads, A and B. When B is active it cuts the scan rate in half.
+- The unit has 4 digital outputs in addition to X/Y/R/G/B, B1 thru B3 and a SH(utter?)
+- The DACs for R G B channels are 8 bit DACs, but two of the data pins are tied to ground
+- The DACs for X and Y appear to be 12 bit
