Actually, the
calculators I had in the front of my mind were the HP
49G and the TI 89.
Since you said "pocket scientific calculator", I infer that you have at
least one really big pocket! :-)
Jacket pockets, trouser pockets, none particularly oversized... it's not
a tight squeeze unless I put the HP-49G and my wallet in the same pocket
at the same time.
Now if I wore jeans it'd be a different matter.
