Notes::

"Orange" is officially "Mandarin" (early) or "Coral" (later) -32S's.

This was the first product to not store variables whose values are zero.

There was a "50th Anniversary" version made of this machine and the
14B.  (The anniversary was of HP.)  The changes consisted of a
modified bezel with insert and an extra logo imprinted on the case.
The 14B version was oversubscribed (i.e., more people wanted one than
were avaiable) and the 32S version had extras (there were some that no
one wanted (then!)).
