Spectaculator emulates the 16K48K12822A3 Spectrums, the Russian Pentagon 128 and Scorpion ZS256 clones, and lots of additional hardware.

Will even play the multi-channel music on games such as Fairlight and Arkanoid correctly.

Any supported joystick can be emulated through the PC keyboards arrow, tab and right alt keys.

Even generates the sound of the Microdrive motor (with and without a cartridge inserted).

Disk images can be write protected, formatted, ejected and inserted.

Output can be saved to disk, copied to the clipboard or sent to a real printer.

Aimed squarely at the Secondary school, this would be the calculator of choice for any student.

Some of the new features that make this compelling for me are as follows: NUMBER The incredibly high definition screen and multi-line display options make it easy to enter calculations and see answers in textbook style and clarity - be they with fractions, brackets, surds (roots), or any combination.

The new Random Integer function makes it easy to simulate coin flips, dice rolls and even card selections or lottery draws, opening up possibilities for a huge variety of mathematical experiments and games.

Factorising large numbers into powers of prime factors with a single FACT command - amazing.

ALGEBRA Incredible power to solve equations and systems of equations or inequalities.

The machine will solve algebraically any polynomial equation up to 4th degree (quartics).

It can find a root for any general equation using Newton-Raphson to refine a user-supplied initial approximation.

Similarly systems of simultaneous equations now go up to four equations in four unknowns.

Also, by using the Inequality function on a quadratic, cubic or quartic polynomial, one can quickly find the points on the graph (if any) where it crosses the x-axis.

The previous limit was 3 x 3 matrices, although even this was sufficient to handle most exam questions.

STATISTICS This was, for me, the main reason for my purchase.

I can now finally dispense with my statistical tables - Binomial, Poisson and even Normal distributions are now covered completely.

For example, one can calculate the probability that three coins out of five will show Heads (0.2734375); the probability that a person is taller than two standard deviations from the mean (0.05399096651); a two-tailed 95 Normal confidence interval (- 1.959964028) etc.

All with a few taps - just entering the values and reading off the result.

Note to CASIO - add in Chi-Squared values and you will have all the lab scientists and social scientists queueing up as well - Mean, Sum, Population Standard Deviation, Sample Standard Deviation, Min, Max, Median, Q1, Q3 REGRESSION - Linear regression - Quadratic regression - Logarithm regression - E exponential regression - ab exponential regression - Power regression - Inverse regression OTHER FUNCTIONS Vectors - including Scalar and Cross Product up to 3-D vectors Calculus - numerical differentiation and integration Complex Numbers - Work with both ModulusArgument and Cartesian form SUMMARY Natural display, powerful new functions and the same ease of use in an affordable calculator from one of the worlds most trusted calculator manufacturers make this the most highly recommended product for school use currently on the market.
