Demo software for electronic simulation

As more and more people avail themselves of the opportunity to interconnect computers via the Internet, software development houses begin to recognize the vast potential of this new medium. This month's efectronics on-fine page presents a number of sites (Internet addresses) used by software developers to ofter demonstration vers ions of their electronic simulation programs. These programs are often weil worth looking at by the advanced hobbyist because the limitations of a demo version can be waved aside, or at least tolerated, for applications at home by the individual hobbyist. Furthermore, the Internet is a vast resource when it comes to collecting Spice models.
