HP 32S Scientific HP 32S
Introduced on June 1, 1988, along with the HP 22S above. Its capabilities came very close to the HP 41's, though they were hidden again in a menu structure controlled by a single orange shift key. It included the RPN version of the equation solver. Code name: Leonardo. Original price: $70

HP 42S Scientific HP 42S
Introduced on October 31, 1988, this was the replacement of the HP 41. It included extensive matrix and complex number calculations.

The code name Davinci shows the close relationship with the 32S Leonardo (above), but the price directed that this one was a much more powerful model.
Code name: Davinci. Original price: $120
