Introduction
PCalc 3 is a brand new version of my veteran calculator application from 1992. It is a fully featured scientific calculator for Mac OS X with support for hexadecimal, octal and binary calculations, as well as an RPN mode, parentheses, programmable functions, and an extensive set of unit conversions. A Dashboard Widget is also included with the main application.
PCalc was the first piece of Macintosh software I ever wrote - I started it in the summer of 1992 to learn how to program the Mac while I was at university. It has been rewritten from scratch twice now. The first time was in 2000 with the release of PCalc 2, so I could learn about programming Mac OS X. A special release of PCalc 2 was included by Apple with Macs sold in the US and some other countries during 2002.
With PCalc 3, I've rewritten it once again to take advantage of five years of advancements in Mac OS X.

System Requirements
PCalc 3 requires Mac OS X 10.4.2 or later and is distributed as a universal binary with support for both Intel and PowerPC processors.
Payment
This release of PCalc is shareware. That means you can download it and try it out for free, but if you continue to use it you are expected to pay the US $19 registration fee. TLA Systems employs me and my wife Saskia full time, so registering your copies of PCalc and DragThing really does make a difference to us.
PCalc 3 is a free upgrade for registered users who previously bought PCalc 2, and your existing serial numbers will continue to work. A special upgrade price of US $10 is available for those people who got PCalc 2.2.3 included with their Macs.
