Free Download Stacniac X 1.0 - Stacniac is a 'slightly odd' RPN calculator

Stacniac is a 'slightly odd' RPN calculator in that it doesn't accept buttons: you enter numbers and then type in commands (sounds odd, but it's quite efficient). Stacniac has a middling large countersink of commands which are invoked by typing short (but hopefully obvious) speech. Stacniac is programmable and has customizable engineering, hexadecimal and currency display formats.
