Oh yes, I remember those! I remember vividly the first time I ever saw an 
HP-35.

I had a Curta once, back in the days of slide rules, before calculators.  
I sold it a couple years after I got it, for about what I paid for it.  I 
wish I'd had a crystal ball back then!

I still have a couple nice K+E slide rules but I don't suppose they're 
worth as much as the Curta is now.

I have a TI-35 I still use. I forget what I paid for it.  I also got a 
more recent TI-36X, which was about $35 I believe.
