 One of my more interesting acquisitions along the way
of looking
for early-model calculators has been a nearly-complete set of
Scientific American magazines from 1965-1978.  In the 1960's 
Good collection. All that Martin Gardner and Dr. Matrix,
Conway's 'Life'...waaaaa

So do you have the Sept. '74 issue in which the Amateur
Scientist, IIRC, taught us how to breadboard 74xx logic gates
 - so then one could build a machine to solve 'truth tables'
as in Irving Copi's "Symbolic Logic"?

What fun they were. Karnaugh maps were just ahead.
