- Full visibility of all data and program memory.

- A paper tape register that supports manual print-out as well as automatic and program trace modes.

Version 1.5.0 adds support for the Mac App Store as well as the following features:

- Copy paste support for the number being displayed

- Delete key support to edit the number currently being entered

- Better support for the paper tape register functions

- Bug fixes as reported by users

Release notes:
Fixed a problem processing numbers when the number system did not use a period for a decimal point.

Removed outdated save options that were added before Mac OS Lion. It now behaves closer to default system behavior to save files on quit.
