EGOR testing

[breathtest2002 at juno.com]

Hi guys!  I am new to this list, but I thought I would inquire as to what
you are using to lay out and design the PCBs?  The reason why I ask is my
dad has all this software for this kind of thing.  I think he uses Pspice
and some other schematic and PCB layout tools.
