All I can say is DAMN...

What an engineering marvel. Of particular interest is how they
implemented the delay line memory. I am just in awe when I think
about this in relation to the desktop PC that I am writing this on.
And to think that now you can buy a pocket calculator at Wal-Mart for
$1.00.

Thought folks here would enjoy this especially because of the discreet
germanium transistor logic. (mama mia!) I wonder where they found
technicians to work on those beasts...

Wow, the days of the $2200 4-function calculators are long gone! 8*)
