Again, thats why I made emphasis on "stock", yes there are a lot of great apps for the HP out there. Although I would surely appreciate if you could pinpoint to some good EE apps for the Prime.

I don't see any support in any of these packages for digital signal processing convolution, z transforms, etc.

MATH and ELECTROPACK by Heuson contain ZTRANSF: Ztransform, solution of difference equations...
======================================================================================== BODE 2.31 http://www.hpcalc.org/details.php?id=5825 Alain Robillard  Thomas Reitmayr PDF manual http://download.devbase.at/hp48/bodee.pdf * Detailed analysis of all zeros and poles of the given transfer function. * Construction of the multiplied and the factored form of the transfer function. * Graphical output of a linear approximation and the smooth characteristic of gain and phase. * Axes of graphs labeled in powers of ten (frequency ), decibel (gain) und radiants (phase). * Arbitrary dimension of the analysis protocol through organization in text pages and scrollable graphical pages. * Easily understandable input format. * Preservation of the last calculated data, which can be recalled at any time. * Special menu entry for multiplying and factoring a polynomial. ======================================================================================== BodeRouth http://www.hpcalc.org/details.php?id=3176 Apolonio Francisco Gonzalez Herrero (APO) BodeRouth plotting program with many features. Requires NeoPolys to run. * Simplicity: Almost the whole commands have been made with input forms with different fields, whose default values are as often as not enough to obtain a nice result. * Graphs diversity: In the same library the majority of the necessary tools for system analysis and design (Bode diagrams, Nyquist, Nichols and Root Locus, as well as the system response to different inputs pulse, step, ramp, sine) have been included. * System types: BodeRouth works with continuous and discrete time systems, including a tool that discretize continuous systems by means of the two methods most commonly used (zero holder and bilineal transformation). * Accuracy: One of the main aspects considered when creating this library was to make the results be as most exact as possible. In this connection some small routines have been programmed to avoid problems related with the calculator such as rounding errors, angle limitation between 0º and 180º and so on. ======================================================================================== LOGPLOT http://www.hpcalc.org/details.php?id=6311 Takashi Matsubara This library makes logscale graphs for the 49G/49g+/50g. Plot types "Function", "Scatter" and "Parametric" are implemented. In the type "Function", TRACE and (X,Y) in the 49G plot menu are available. Nonuniform logarithmic tick, zoomin, zoomout and recenter are implemented. Faster than previous versions. ======================================================================================== FUMO  DSP Toolbox http://www.hpcalc.org/details.php?id=4898 Przemyslaw Holubowski FUMO contains functions allowing digital signal processing. It allows sampling typical or user defined signals, applying window functions, applying FFT (or DFT) transform, convolve, zeropad, and get frequency, phase or group delay responses. Documentation also in Polish. Now requires free registration. ======================================================================================== FFT with Plotter http://www.hpcalc.org/details.php?id=6785 Frank G Baird This is an FFT program taken from Oppenheim and Schafer's Digital Signal Processing. Also included is a neat little program PLFFT which plots the magnitudes the results of the FFT program. ======================================================================================== Fourier http://www.hpcalc.org/details.php?id=6790 Dennis York A set of programs for digital signal processing. Included are: Discrete Fourier Transform (also does inverse), Fast Fourier Transform, Inverse Fast Fourier Transform, Fourier Transform (selects FFT or DFT depending on size), Inverse Fourier Transform (selects FFT or DFT depending on size), Periodic Convolution, Aperiodic Convolution, Two Dimensional Fourier Transform, Inverse Two Dimensional Fourier Transform, and Axis Shifter for use with Two Dimensional Fourier Transforms. ======================================================================================== Neopolys http://www.hpcalc.org/details.php?id=3169 Apolonio Francisco Gonzalez Herrero (APO) A definitive polynomial library. Supports Laplace and Z transforms.

Well, I can offer an opinion on that. 25 years ago I was quite happy with the display of my HP28C and 28S and I would have been blown away by the HP 50g display. But serously, my eyesight is not what it was back then, and  having just bought a HP 50g  I _am_ struggling with the display. I couldn't care less about colors, that is not what is important, but I would have loved for the display to have light somehow. That would make the calculator a LOT easier for me to use.
