[QuadList] anyone have one of these colorizers!?

Gary,

Thank for sharing this image. I have that same slide scanner and it takes a ton of work to get a good image out of it. I enhanced your picture to try and read the identifying marks.

I won't keep it there permanently, so save it if you want it please.

So, if I'm reading it correctly the mixer is an EMI?

I had a friend named Kelly Hickok who worked at KOLN, probably in the early 1980's.

Thank you again,
Scott Thomas

We used one of these at KOLN in Lincoln.  Originally It was a separate frame but was integrated with the mixing electronics.  Here is a poor photo of the mixing electronics and switcher rack.  We only used the colorizer as a color background generator but if you fed video into the unit, you could get more or less a different color at different luminance levels.  I don’t think I saw us use it other than playing around.

The Riker modules in the three chassis were actually copied by the Engineers.  Some modules were bought and others were hand made from the schematics.  I wish I would have kept the schematics because a single module was drawn on one sheet of paper about 20 feet long.  Giant transistors.  I had a Riker sync generator at home but didn’t keep any of it.
