Kyle,
Where did you find that part? I designed the video stage of the AT&T Pixel
Machine back in the late 80's using that part. It was perfect for us as I
had to access up to 16 cards worth of pixels in TTL and spit out a video
rate stream in ECL to drive the lookup tables and the DACs. Only time I've
ever designed a backplane with active parts on it.
Very cool! I found this one in the bwtwo framebuffer for a Sun 3/60. They
didn't seem to use the chip in other Sun machines, far as I can tell.
