"The HP-95C was developed at the same time as the HP-25C, the HP-67 and the HP-97, but was never sold to the public. This makes it extremely interesting to collectors and historians of HP calculators... I believe that fewer than 20 exist... It was apparently meant to be a printing version of the HP-25C, much as the HP-97 was a printing version of the HP-67... A fascinating calculator, and in a way it is a pity it was never sold to customers" Wlodek Mier-Jedrzejowicz.
