Harold: 
 Thank you. Is this your web site? 
 There are a lot of very interesting material in this site. 
 I'd like to thank whoever that compiled those valuable information. 
 I personally never used the Slide Ruler. 
 I remember, back in 1976 when I entered university, I was 16. At that time, it was "almost" the end of "Slide Rule" era and the beginning of emergence of calculators.
