Tape Calculator

by Russell Haines

Welcome to the homepage for Tape Calculator. I designed Tape Calculator to replace a standard desktop adding machine, allowing 10-key touch number entry. Tape Calculator is for high-speed adding and subtracting of numbers and being able to verify totals.

How it works: Entry is similar to a desktop adding machine.
Enter the number first, then press either add (+) or subtract (-). (Multiply and divide don't work.)
The Enter key on the keypad also acts as the + button on an adding machine.
Pressing clear (Num Lock) clears the current entry.

Pressing = or [Return] totals and clears the tape.
Pressing + or - or [Enter] without entering a number also totals the tape.
Use the Info button to toggle between floating and +2 decimal operation.

Current version is 0.3:
Pressing Enter key on the keyboard is again treated as add (+).

Requested features for later versions:
Tapes longer than 25 items.

Download:
Dashboard widget (OS 10.4+).

Mac OS X 10.4 Tiger and above is required. If you're using Safari, click the download link. When the widget download is complete, Show Dashboard, click the Plus sign to display the Widget Bar and click the widget's icon in the Widget Bar to open it. If you're using a browser other than Safari, click the download link. When the widget download is complete, unarchive it and place it in /Library/Widgets/ in your home folder. Show Dashboard, click the Plus sign to display the Widget Bar and click the widget's icon in the Widget Bar to open it.

Coming Soon:
