HP-33S Calculator

The HP-33S calculator is no longer in production, but it is a very capable instrument for middle-range computations, especially for general surveying work. Over the years, a number of programs were developed for the HP-33S, and these can be downloaded from this site. In addition there are some other materials, such as links to HP training, the User Manual, and other useful connections.
