`oscope' is a digital 44kHz oscilloscope for /dev/dsp. It is based on Jeff Tranter's original work described below but has been significantly enhanced.
First production release.
Requires a kernel supported sound card that can do 8800Hz - 44kHz, the `libsx' package to build the xoscope X11 client, the `svgalib' package to build console-based oscope, the `g3vga' package to add console text, and a mixing program to select input source and level.
Includes oscope for SVGA console display and xoscope, an X11 client. Features include 8-bit sampling of 2 channels at 44kHz, 5 us/div to 5 ms/div time scale, 5 automatic measurements, built-in and external math functions including sum, diff, avg, and FFT, 26 memory buffers, 8 simultaneous signal displays, and file save/load.
The oscope package may be obtained from either sunsite.unc.edu or from its home site at: www.bobsplace.com.

Scope is a simple software emulation of an oscilloscope. It graphically displays voltage as a function of time.
ALPHA. First release.
Sound card with input capability supported by the kernel sound driver. SVGALIB is used to do the display work.
Scope uses the /dev/dsp device to take audio in from the
soundcard and displays it on the screen in a manner similar to an oscilloscope.
Jeff claims Scope was written more for amusement value than for any serious
purpose.
You can obtain source, makefile and man page for Scope from: sunsite.unc.edu

An X11 based interactive printed circuit board design tool.
Vers 1.4.1, stable.
X11 Windowing system and a recent flex program.
The pcb package comes with good instructions on how to compile and install the software. I compiled it without error under X11R6. It comes with package layouts for a range of popular components and the example layout nicely demonstrates the capabilities of the package.
You can obtain the pcb package from: sunsite.unc.edu or from: ftp.uni-ulm.de

An event-driven logic-level simulator for MOS circuits
Version 9.2, production.
X-Windows.
irsim is an X11 based simulator for MOS circuits. It has two simulation modes, either switch where each transistor is modelled as a voltage controlled switch, or linear where each transistor is modelled as a resistor in series with a voltage controlled switch, and each node has a capacitance.
You can obtain irsim from: sunsite.unc.edu.

Spice is an analog circuit emulator.
Stable release.
Unknown.
Spice allows you to design and test circuits in a computer modelled
environment to see how they will behave without having to touch a soldering
iron, or solder. A readme file comes with the package. To install I
did the following:
# cd /usr/src
# gzip -dc spice3f4.tar.gz | tar xvf -
# cd spice3f4
# ./utils/build linux
# ./utils/build linux install
You can obtain version 3f4 of Spice from: sunsite.unc.edu

svgafft is a spectrum analyser for Linux.
Alpha, but usable.
F77, Linux supported sound card, svgalib, a 486DX33 or better.
svgafft uses the /dev/dsp device and currently supports 16-bit
and 8-bit sample resolution on supported Linux soundcards. It's display is
something akin to a high-end spectrum analyzer with falling peaks. Andrew
is working on an X-Motif version to be released soon.
You can find the software at tsx-11.mit.edu and sunsite.unc.edu.

freq5a1 uses the /dev/dsp device, samples the incoming
audio, performs a fast fourier transform on the data and displays the
output in either 640x480 VGA or an X-Window.

ObjectProDSP is an object oriented tool for design, development and implementation of Digital Signal Processing. It allows you to design your DSP network, runs simulations with oscilloscope style plots and listings at any point in the network.
alpha.
XFree86 3.1.1 or better, g++ from gcc 2.6.3 or better, 32Mb of total memory (real+swap) recommended, 6Mb of disk space for minimum configuration, 40Mb disk for full installation.
There are a number of files that comprise the package. There is a binary only package for Linux which I recommend you start with. There is comprehensive documentation included from which you can obtain installation and operation instructions.
You can obtain ObjectProDSP from: sunsite.unc.edu, tsx-11.mit.edu, or ftp.funet.fi. There are a number of files that comprise the package, some of the quite large so be prepared.
