Several years ago I bought a copy if IS-Spice.  From what I could tell, the
software was a slightly modified version of the original Berkely code (Fortran
version).  Some features of the original code were missing, presumably to
make things fit into 640K, but nothing drastic.  Performance was reasonable, 
and in most cases, numeric results matched those obtained from a workstation 
version of SPICE.  The software required a math coprocessor and did not come 
with a parts library.

What you don't get for $95 is graphical output (unless you consider line
printer plots graphical).  At the time, Intusoft sold a package called
SOFT_SCOPE ($175) which post processed any Spice 2G.6 output file.  It worked
OK, but only with a CGA monitor.  I found it difficult to use.

Berkeley has re-written Spice II in 'C' and called it SPICE III.  I thought
they were also working on a PC-Version.  Perhaps someone in net-land can fill
us in on the project. 

Of course these are my own opinions, and not those of my employer.
