Dave,
Oh yeah, another site I was recommended to get Tesla Coil software is 
<http://www.5000downloads.com/miscellaneousutilities/TeslaMap5.7.htm>http://www.5000downloads.com/miscellaneousutilities/TeslaMap5.7.htm
I haven't tried these, they are just what was recommended to me. I have 
downloaded both of them, this one and WinTesla that I wrote about before, I 
just haven't had the time to run through the parameters I have planned.
Paul
