Free42 is a complete re-implementation of the HP-42S calculator 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.
What's New in This Release:
· HMS+ and HMS- would return results with the wrong sign under certain circumstances: result < 0 and |result| < 59 seconds, or result < 0 and |result| > maximum integer. Fixed.
What's New in 1.4.70:
· Fixed several bugs in complex ASIN, ASINH, ACOS, and ACOSH.
What's New in 1.4.68:
· INVRT did not perform any type checks, leading to badness when it was applied to anything that wasn't a matrix. Fixed.
What's New in 1.4.66:
· Removed the "Not Yet Implemented" Time functions; I decided not to implement them. They're also gone from the FCN catalog. The ADATE, ATIME, ATIME24, CLK12, CLK24, DATE, DATE+, DDAYS, DMY, DOW, MDY, and TIME functions remain; those are the time/date-related functions from the HP-41 Time Module that are actually useful in Free42. The functions that I decided not to implement after all are the following: Live clock display: CLKT CLKTD CLOCK Stopwatch: RCLSW RUNSW SETSW STOPSW SW Alarms: ALMCAT ALMNOW XYZALM Clock control: CORRECT RCLAF SETAF SETDATE SETIME T+X
· In DMY mode, DATE would display dates as DD:MM:YYYY, but that should be DD.MM.YYYY. Fixed.

SoftBase Parser SoftBase Parser - enables you to evaluate easily any kind of mathematical functions.
You can use up to 6 function parameters named x, y, z, u, v, w.
Furthermore it is possible to change the base of the input and output value (e.g. binary or hexadecimal) and the angular unit (e.g. degree).
Example:
Set function to
-sin(x*cos(x))^(1/x)
and x to the value
0
SCX Calculator SCX Calculator - SCX is a general-purpose high-precision calculator that combines standard mathematical functions with pricing functions needed in the business/retail world. It's designed for simplicity and ease of use.
· SCX has a large, easy to read 15-digit display with 30 digits of internal precision
ACalc ACalc is a scientific calculator using double precision math with 15 digits of display.
Formula entry is algebraic (EMDAS). Usage is natural and intuitive, with a simple main window consisting of number -operation- and function keys.
What's New in This Release:
· Argument checking for arctanh is now correct
Unc: A Units Calculator Unc: A Units Calculator - Unc is a calculator which runs on the 3Com PalmPilot. Unc has a number of features not often found in other calculators:
- Units. One of Unc's main features is its ability to calculate using units, like feet, miles, pounds, meters, seconds, and so on
