What is that? j/k!!

Nice slide rule. Is it dimentionally accurate?

Nice slide rule. Is it dimentionally accurate?

My high school physics teacher had one of those but white over the chalk board. Used to challenge calculator students to duels. He always won. The clacking was loud.

I still took my slipstick into important exams all through college. Saved my butt once when my calculator batteries died. Still have it somewhere.

I did take a small one with me to the grocery store for many years. It was the quickest way to see which box of calories was the cheapest.

Now where did I stick my copy of the CRC Tables?

Taking some engineering class with about 50 students, IIRC. The professor asked how many knew what a SR was. About a dozen held up their hands. Then he asked how many have actually used one. Only 3, including myself.

Oh, how far have we fallen!

I have been thinking, if I can find my CRC Tables, building a little wood box with glass front. Inside would be the CRC Tables and a slide rule. Outside a small hammer on a chain. A sign on it "In case of power failure break glass".

It would be heresy to built that box with CNC cut parts.building a little wood box with glass front

Maybe add a 4H pencil and pad of paper?

CRC was that little book with tables of numbers and formulas you grabbed before every calculator had sin/cos/tan buttons to push I think I have one on a shelf somewhere.It would be heresy to built that box with CNC cut parts.

They're definitely before my time.

And tables of Log and Ln functions.CRC was that little book with tables of numbers and formulas you grabbed before every calculator had sin/cos/tan ....

Would it be OK to use a CNC that was programmed by paper tape created on a PDP-8?It would be heresy to built that box with CNC cut parts.

Pretty sure there were a few versions offered depending on what math you needed.Little?

Y'all may have encyclopedia versions - but they also made little pocket sized reference ones for us idiots in the field

Considering that my brother said they were still using paper tapes to program his Phalanx guns when he retired, about 6 years ago,Would it be OK to use a CNC that was programmed by paper tape created on a PDP-8?

I made my TIG welding cart from a hard drive cabinet from a PDP-10. Stout

I used bags of punch card chads as insulation in the atic of the shop at one time. Not exactly fire resistant - but they were free.
