Free42 v1.4.66 is released.Free42 is a complete re-implementation of the HP-42S scientific programmable RPN calculator,was made from 1988 until 1995 by Hewlett-Packard and the HP-82240 printer. Free42 was written from scratch, without using any HP code. You do not need any ROM images in order to use it, yet it is fully HP-42S compatible.

Free42 v1.4.66 Changelog:

The latest version is 1.4.66, released April 8, 2010. NOTE: The PalmOS package is still version 1.4.62; I need to re-test the ARM builds but my test machine died and I need to get a replacement first. I expect to bring the PalmOS package back in sync with the others in the next week or two. For more information about what's been going on with Free42 in the past, see the project HISTORY; for my thoughts about future development, check my TODO list.
