I have this interesting old machine, from Sperry Gyroscope Ottawa (Canada) and I'm trying to find out if anyone has seen one.

It's quite a machine, three rackmounted cases with cards and cables to connect it together. It has a power supply/control unit, a time base, and the data processor.

The task of the computer is simply to calculate a number based on an input of pulses vs. time. More or less an enormous high accuracy digital frequency counter if anything.

Just thought it might be interesting to post about this old thing. See if anyone knows of it.

He didn't upload them.. They are hosted on another server and he's using the img bbtage to display them in his post.

Yeah, they're hosted on my server.

Yes, the computer is old, 1963 to my knowledge. And it seems to be completely unknown to anyone I find.

I don't know... It just seems as if no one knows about it.

Our FAA used a system named RVR which would tell Air Traffic Controllers about visibility at runway level. There was also a RVV.

All major air systems measure RVR, but not many of them seem to have this exact computer.
