Brings back memories. I had one of these too.

I have a couple of those too, but mainly set up for aviation use. Happy Pi day!

Cool shot for the day. I have circular slide rule somewhere. Haven't thought about until I saw your image.

I have never seen a circular slide rule! I still have the ordinary slide rule I used in school.
