The S.A.O. Megacam focal plane will consist of 36 large CCDs (2 K X 4.5 K format), each with 2 output ports running at pixel rates up to 200 kHz. The unbinned data field is thus as large as 324 megawords and is presented at a sustained data rate during readout approaching 28 megabytes/sec. We have developed a simple camera controller to deal with the problem of handling so many channels and their digitized outputs at fairly high speeds. We also present some results from ongoing efforts to optimize the 200 kHz signal processing chain for low noise and low crosstalk.
