Newton Lowdown is a simple desk accessory (DA) for the Macintosh (will not work on other PCs, or Windows, I am afraid). To install it, simply drop it into the Apple Menu Items folder in your System Folder (if you have System 7 installed). If you are still using System 6, then you will need to use Font/DA Mover to install it in your System File, or use Suitcase or similar.
Newton Lowdown provide a quick desktop reference to NewtonScriptÅ commands which may be of use to those programming the Newton direct (e.g. through our NewtonScript Runner utility). It also guides you through the currently documented error codes, with a little help from Monty Python.
About SciCalc - the first scientific calculator for the Apple NewtonÅ
Version 1.0b2
SciCalc is a simple implementation of a standard (i.e. NOT Reverse Polish or 'RPN') scientific calculator for the Apple Newton MessagePad and similar PDAs. This is the first release version, which has so far only been tested by the developer. If you do find problems, please let me know so that I can rectify them in the next release.
To load it into a Newton MessagePad, you must have a Mac (on which you should be reading this!) and the beta Connection Kit. Simply connect your Mac to your Newton, and install the Calc102.pkg file as a Newton application, down the connection to your Newton.
Bug fixes this version:
In the first posted version, an error (-8007) occurred when dealing with numbers using the thousands separator (e.g. ','). This has now been fixed and thousands, millions, etc., should now work fine throughout. I also hope that this is independent of the number format being used (i.e. what the thousands separator is).
Current features:
All floating point numeric calculations normally found on a basic 'scientific' calculator, including a wide range of trig and exp/log functions.
A single number display, edited by button use only.
Two standard financial functions.
Two user-accessible memorys, which include summation functions.
Constants Pi and e available from keys.
Conversion to and from radians and degrees.
Planned features:
Hexadecimal math (possibly even with hexadecimal point!).
Copying of result to other Newton apps.
My own error/exception trapping.
Note that currently the hex keys (A-F, and the radio button to switch between them) are non-functional.
All routines used are standard built-in Newton math routines, except for the degree to radian conversions, which are simple arithmetic ones.
Note on key naming:
x^y is 'x to the power of y'
sqt is 'square root'
exp is 'e to the power of'
ln is 'log to the base e'
log is 'log to the base 10'
d>r is convert degrees to radians
r>d is convert radians to degrees *** note that all trig is performed in radians***
sin, cos, tan are as they say
asin, aco, ata are arcsine, arccosine and arctangent
sinh, csh, tnh are hyperbolic sine, cosine and tangent
asih, ach, ath are hyperbolic arcsine, arccosine, and arctangent
erf is the error function
erc is the errorc function
ga is the gamma function
annuity calculates the present value factor of an annuity at a given interest rate over the specified periods, the interest rate being per period. The first number entered is the rate, the second the periods. Enter as <rate><annuity><periods><=>.
compound calculates the compounded interest factor over the specified number of periods. The first number entered is the rate, the second the periods, as per annuity.
The keys to the right of, and below, 'M1,2' are the memory access keys - the left column for M1, the right for M2. In each case, the keys mean:
-> saves current display to memory
+ adds current display to memory and stores result in memory
<- replaces current display by memory
C clears memory contents to 0
Pi produces the value of Pi (3.14159....)
e produces the value of e (2.71828....)
clear all clears everything except for the two memories
CE clears only the rightmost character in the display (works on all display entries!)
+/- negates the sign of the display, i.e. + becomes - and vice versa.
Note that errors are currently not trapped - if you divide by zero, then you will get a standard Newton divide by zero error. Similarly, finding the log of a negative number will fill the result with 'box' characters. Very occasionally, you may find that the contents of the display are lost - just press 'clear all' to get a 0 back. I hope to improve this in future versions.
This is a simple Newton application that does a bit of view animation uses downloaded sounds.
This was done mostly as an exercise in how fast I could bang out something that would impress my kids. Hopefully, it will also help a few budding Newton programmers a bit.
Have fun.

[*] Mastermind 1.02.hqx
Welcome to Master Mind 1.02
Copyright 1993, Michael Herman, All rights reserved.
Master Mind is a simple game where you try to guess a four digit number. Simply enter the number at the bottom and tap "Guess". Spaces and periods are ignored. Your guess will then appear in the guesses list followed by two numbers. The first number is how many digits were correct and in the correct location. The second number is how many digits were correct and in the wrong location. If you get frustrated, you can tap "Show" to see the number. "New" generates a new random number (Hint: the number will be between 1000 and 9999). You can use the up and down arrow at the bottom to scroll the guesses list.

Welcome to Mine Sweep 1.00

The object of Mine Sweep is to locate and flag ten mines. To flag a mine, tap once. If a square is safe, double tap on it to reveal the number of mines adjacent to the square. Victory is yours once you have flagged all ten mines, but if you double tap on a mine...

The prime purpose of this is to call a garbage collection in your Newton's memory. In theory, such a garbage collection should get rid of all the dross hanging around, and you may find that this staves off the need to restart from time to time (when using version 1.02 of the Newton OS).
It incidentally includes information about free and total memory, battery power, and battery compartment temperature, all of which are available in other tools on the Newton. However, try tapping on the temperature bar...
This is a slightly modified version of one of the demos provided with the Newton Toolkit. NewtonScript, which is the language used to program Newton systems, can be compiled and run on the fly, and this little utility allows you to do just this. You will hardly develop the next killer app on your Newton this way (!), but it does for instance allow you to work out sines etc.
To use this, enter your NewtonScript program in the upper editable text field, e.g.
sin(0.75)
then press the Eval! button, and the answer is displayed in the lower text window.
Note that it is possible to enter *any* NewtonScript command in this, and thus it is very easy to crash your Newton in a myriad of extremely nasty ways. BE WARNED!

Documentation for RPM's Object Viewer, version 0.92 1993 August 21
What is it?
The Object Viewer is a Newton application intended mainly for programmers. It displays the contents of objects in Newton's memory, and provides several ways to jump from one object to another. It is a floating window which is half the nheight of the screen, and can therefore be used to examine the activities of other Newton programs while they are running.
