NeoCal for Palm OS User Guide
Since there are many files distributed with NeoCal, they have been packaged into a single, compressed file. These must first be decompressed onto the hard drive of your desktop computer.

If you are experiencing any problems with the installation, please check your handheld's manual for more information about installing third-party software.
