I would replace the Windows calculator with
it. Been using RPN since about 1976 so anything else "normal" is a pain.

Have you seen or tried Xcalc?

XCALC is my little hobby project -- a Win32 (2000+, 98+) RPN calculator
completely free to use, and immediately downloadable from he

(But please read the Spiceware section below!)

XCALC version 2.9.4 (190 kB zip)

Other versions - see below.

The latest release of XCALC is version 2.9.4. This makes writing XCALC
programs quite a bit easier.

I have only tested this version on Win XP pro, but I assume it works
well with any version of Windows upwards from 98 or 2000. I believe
that neither NT4 nor Win95 will do any more. Wine (under Linux) works
mostly quite well, but read the bugs section under online help
(admittedly a little difficult, since the main problem is help support).

If you have any queries, praise, complaints or whatever, do drop me a
line. You'll find a clickable item in the XCALC about box. The only
condition for your using XCALC is that you send me an email...

Found at:

It ran okay on my old WinNT4 machine ~6 months ago.
