Personal Calculator Collection

Dear MathTypes,

Ever since reading an account of the endeavors of Charles Babbage, I  
have been assembling a personal collection of electronic hand-held  
calculators.  Someday I will probably write a paper about these early  
electronic computing machines.  To complete the collection, I need  
calculators primarily from the 1970's (LED display types) of any make  
and model.
If you would like a permanent home for your old calculator, or if you  
know anyone who has one I might be interested in, please contact me.
