This
Canon LC-33 looks different to its predecessor LC-31
and makes use of a novel manufacturing technology.
Instead of using a traditional printed circuit board
(PCB) the LC-33 uses a flexible foil pressed against a heavy metal sheet. Not
only the LC-display but even the calculator circuit missed any solder joint.
We noticed this construction already with the LX-30
and LX-40, too. Main differences between this LC-33 and
the two LX sibblings are the 3-key versus 4-key memory and the [+/-] function.
About two years later we Canon introduced with the LC-34 a traditional design again.
Don't miss the colorful LC-33 versions featuring the PEANUTS Characters,
we know them with a white, yellow and pink
housing or the PADDINGTON BEAR in a white
housing.
