     Description
        An X11 based interactive printed circuit board design tool.

     Status
        Vers 1.4.1, stable.

     System requirements
        X11 Windowing system and a recent flex program.

     Detail
        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.

     Where and How to obtain it.
        You can obtain the pcb package from: sunsite.unc.edu
        <ftp://sunsite.unc.edu/pub/Linux/apps/circuits/pcb-1.4.1.tar.gz>
        or from: ftp.uni-ulm.de <ftp://ftp.uni-ulm.de/pub/pcb/current>

     Description
        An event-driven logic-level simulator for MOS circuits

     Status
        Version 9.2, production.

     System Requirements
        X-Windows.

     Detail
        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.

     Where and How to obtain it.
        You can obtain irsim from: sunsite.unc.edu
        <ftp://sunsite.unc.edu/pub/Linux/apps/circuits/irsim-9.2.linux.1.tar.gz>.

        Radio operators. It will include a fully featured Linux
        installationplus a range of amateur radio specific software such
        as those listed in this document. Bruce has detail and updated

  13.2.  SunClock

     Author
        John Mackin, john@cs.su.oz.AU

     Description
        A clock that will show you instantly what parts of the globe are
        exposed by sunlight and what parts aren't.

     Status
        Released.

     System requirements.
        X-Windows.

     Detail
        sunclock is another of those desktop gadgets that most people
        think look nice but really don't have a lot of use for. I use
        sunclock to obtain an at-a-glance indication of the time
        anywhere in the world.  In its iconic form it sits in a small
        Mercator projection. When maximised it produces the same image
        but obviously larger with slightly more detail.  It also
        displays the date, local time and UTC. sunclock actually
        calculates mathematically what parts of globe are sunlit and
        which aren't, it seems quite accurate, so long as you assume the
        earth has no atmosphere.

     Where and How to obtain it.
        I haven't seen any precompiled sunclock binaries for Linux
        about, so check your nearest archie server. sunclock compiled
        straight out of the box for me.

        the top of sunclock.c remain intact.

  13.3.  Xearth

     Author
        Kirk Johnson, tuna@cag.lcs.mit.edu

     Description
        A rotating earth for X-windows root window. It has real life
        shading, and options for geostatic view, and non geostatic view.
        A prettier and more modern version of sunclock but requires a
        bit more processing power.

     Status
        Version 1.0.

     System requirements.
        X-Windows.

     Detail
        xearth is a sophisticated program which draws a colour picture
        of the earth onto your X Windows display. It offers either an
        orthographic view as you would see from space or the map like
        mercator projection. You have a number of options in determining
        the behaviour of the view. The details are available from the
        xearth Home Page <http://cag-www.lcs.mit.edu/~tuna/xearth/> and
        in the documentation which is supplied with the package.

     Where and How to obtain it.
        The source can be obtained from its home site at cag.lcs.mit.edu
        <ftp://cag.lcs.mit.edu/pub/tuna/> or just about any X11/contrib
        directory.

        copyright notice included states that xearth is freely

  already know about, or that the entry is obselete or outdated for.

  What I'd like as a minimum set of requirement would be something like
  the following:

     Name
        The name of the software in question.

     Author
        Who wrote, or ported the software. An email address, or some
        other means of contacting them is also essential.

     Description
        A single line description of what the software does.
