  The EL-8 was Sharp's original portable
calculator from 1971 (in Japan in 
 late 1970) and cost $345 back then (for your basic 4-function

That sounds right.  The guy I talked to mentioned that it was IC-based,
not micro-based.

  I don't believe it used the 4004 chip -
relatively few calculators 
 actually did use the 4004. 
I think it was a deal between Busicom and Intel for a calculator chip that
produced the 4004 and started the microprocessor revolution, right?

-- Doug True- although IIRC Busicom didn't actually use the 4004 as things
worked 
out.
There's a nice webpage devoted to the 4004 at:
