1. Calculator II is a pleasant looking color multi-function calculator that runs as an application under system 6.x or System 7. The calculator was written as an application to be run under MultiFinder or System 7 alongside other applications. It improves on Apple’s original calculator by adding trigonometric functions, functions for base 10 and natrual logorithms and their inverses, a memory function for temporarily storing values, and all of these functions can be invoked by using the F-Keys on the Apple Extended keyboard (F5 - F15). The calculator also allows users to correct trailing digits of values entered on the display of the calculator through the use of a backspace key. Balloon help and general information about the program is available under the Help menu under System 7. This software is being distributed as FREEware so give it a try and let me know what you think!
2. Base 10 and Natural logarithms and their inverse functions.
3. Square and Square root functions.
4. Power and nth root functions.
5. Memory functions to store numbers temporarily.
6. Ability to correct trailing digits of values being entered on the calculator’s display.
7. Support for complete operation of calculator functions via the Apple Extended Keyboard (F5 - F15 required).
8. Ability to cut, copy and paste to and from the clipboard.
9. Balloon help is available for menus, About Dialog box, calculator keys, and the icon in the Finder.
10. General information about the program (CalCulator II ReadMe document) is also available under the Balloon Help menu under System 7.
11. Calculator remembers last used position on screen.
D. Keyboard Map for Function Keys
1. The function keys that appear on the calculator are mapped to the Function keys F5 - F15 on the Apple Extended Keyboard. Here is the correspondence map:
F5=sin
F6=cosine
F7=tangent
F8=2nd Function
F9=Value of PI
F10=Natural Log
F11=Base 10 Log
F12=Backspace Key
F13=Power function
F14=Square root function
F15=Square function
2. Other keys mapped to functions on the calculator:
Esc, c, C, Clear=Clear function
*, x=Multiplication
X=Memory Enter
R=Memory Recall
M=Memory Add
?=About Dialog box
Delete=Backspace function
Enter=Equal function
E. Future Plans for Calculator II
1. Make parentheses functional.
2. Option to display commas every 3 digits in results window.
3. Switch to display Statistical, Business, Scientific, or Programmer functions.
4. Option to display negative numbers in red color or parentheses instead of with leading negative sign.
5. Ability to scale the size of the calculator.
6. Ability to retain the memory function across invocations of the application.
7. Ticker tape available for display and output to disk.

Version 1.08 adds some advanced functions and memory. If you are running System 7, you can add this application to your Apple Menu Items folder and it’ll seem like a super-charged Calculator DA. (Note: It’s NOT a desk accessory.)
