I lost my users manual and need the TVM program. If anyone knows where I can get the manual on line orr the code for the program, let me know. I am also interested in other programs for the 42S. Thanks
The manual is available on the museum CDs at:
http://www.hpmuseum.org/cd/cddesc.htm
There are a very small number of 42S programs in the software library. More are always wanted.
I have two "surveying" books from D'Zign software for the HP42 if interested-Vertical and Horizontal alignments.
