* Moffsoft FreeCalc (http://www.moffsoft.com/freecalc.htm)
* calcAnt (http://www.calcant.net/calcant.html)
* AddUp (http://orefa.com/)
* ESBCalc (http://www.esbconsult.com/esbcalc/esbcalc.html)

I almost evaluated gtapecalc (http://gtapecalc.sourceforge.net/), but it
requires GTK and complition.

XCALC (http://www.tordivel.no/xcalc/) is another tape calculator, but it
uses RPN (http://en.wikipedia.org/wiki/Reverse_Polish_notation), which is
useless for most people.

*Moffsoft FreeCalc*
Nice simple interface.
Passed the arithmetic test that ShowCalc failed.
Just simple arithmetic operators.
There is a advanced payware version.

*calcAnt*
Passed the arithmetic test that ShowCalc failed.
Just simple arithmetic operators.
Initially installs with German text. You have to find the Options page to
change to English.
Interesting text editor mode, that you can use to save text files.

*AddUp*
Passed the arithmetic test that ShowCalc failed.
Just simple arithmetic operators.
Slightly strange and ugly interface.
Allows you to remove buttons text, if, like me, you use the number pad on
your keyboard for input.

*ESBCalc*
Slightly ugly, but simple interface.
Passed the arithmetic test that ShowCalc failed.
Includes scientific operators.
There is a advanced payware version.
There is a no-install option.

My favourite was ESBCalc. Its accuracy, no-install option, OK interface
and many features mean it will replace ShowCalc.

If anyone else knows of good tape calculators or proper calculator
accuracy tests, please let me know.
