The software tools in the Chipmunk system perform a wide
variety of tasks: electronic circuit simulation and schematic capture,
graphics editing, and curve plotting, to name a few. The core tools
began their life as the applications software for three clusters of
Hewlett-Packard  9836C computers (and other compatible models) that
were donated to the California Institute of Technology in the early-
and mid- 1980's.  One cluster, of about 25 workstations, served as 
computing tools for undergraduate and graduate Computer Science courses.
A second cluster, of about 10 workstations, served as data acquisition
and analysis tools for laboratory courses in integrated circuits: each 
workstation was attached to donated HPIB test instruments.
A third cluster served the laboratory of Carver Mead. 
	
Throughout the decade of the 80's, Caltech undergraduate
and graduate students wrote a variety of software tools to run on
these three clusters of machines: software to teach classes, do
research, and prepare documents. When the 80's ended, and Unix
workstations began to dominate research computing, the best tools were
ported to run under HPUX running on HP 68030-based workstations
running the X window system, and later to a  wide  assortment of hardware and
software environments.

In 1996, at Pisa University in Italy where I study computer engineering,
during a Elaboration Systems course, I known LOG: an electronic circuit
simulator. After my proof said me that log is part of ChipMunk, and that
he and his group was warking on a MS-DOS porting. So I decided to port
ChipMunk on our favourite computer: tha AMIGA... And here it is!
	
Here is a brief description of each of the Chipmunk tools.

 Log 
   Log is a graphical environment for entering circuit schematics, and
   for analog and digital circuit simulation. 
 View 
   View is a tool for manipulating and plotting data. 
 Until 
   Until is a graphics editor.
 Wol 
   Wol is a tool for creating integrated circuit layout.
	
 In addition to these major tools, many supplementary  tools are part of the
Chipmunk system.
