VERSION - UPDATE: 2.3.5 (05-08-95)
README:
"MathPad is a general purpose graphing scientific calculator. It uses text input rather than simulating buttons on a hand held calculator. This live scratchpad interface allows you to see and edit your entire calculation."
One may be a mathematician of the first rank without being able to compute. It is possible to be a great computer without having the slightest idea of mathematics.

" NumberCrunch is a scientific calculator which can
窶「 compute algebraic expressions,
窶「 define variables and functions,
窶「 graph functions and zoom in on them,
窶「 save often used objects to disk,
and generally just crunch an awful lot of numbers."
The point about zero is that we do not need to use it in the operations of daily life. No one goes out to buy zero fish. It is in a way the most civilized of all the cardinals, and its use is only forced on us by the needs of cultivated modes of thought.
--> Alfred North Whitehead
Many zeroes make big numbers.

VERSION - UPDATE: 3.0 ( Aug. 95)
README:
"窶「 Programmable Calculator is a spin off from AxoGraph, a scientific graphics and data analysis program. A fully functional demonstration version of AxoGraph is available from Axon Instruments (http://www.axonet.com).
窶「 Programmable Calculator is both a numerical calculator and a simple multi-language development environment. Programs can be written in Basic, Fortran, Pascal, or C. A program can be run directly from the source code editor, or it can be loaded into memory and its name appended to the Program menu. Frequently used programs can be saved in the "Drop-In Programs" folder and will be loaded and added to the menu each time Programmable Calculator is run. Programs can interact with the user via standard dialogs that are created with a single line of code."

PCalc
I do hate sums. There is no greater mistake than to call arithmetic an exact science. There are permutations and aberrations discernible to minds entirely noble like mine; subtle variations which ordinary accountants fail to discover; hidden laws of number which it requires a mind like mine to perceive. For instance, if you add a sum from the bottom up, and then from the top down, the result is always different.

VERSION - UPDATE: 1.5 (08-06-93)
README:
"RPN Plus is primarily used to evaluate mathematical expressions and to help solve problems, from the trivially simple to the dauntingly complex. It uses Reverse Polish Notation (RPN) logic in its calculations (with a four register X,Y,Z,T stack). Optionally, numbers and many functions may be keyed in on the computer keyboard. 25 lines of output are displayed on the OP Button Screen."
