Thank you for that offer.

Today I picked some old machine of the doorstopper class (P3 800 MHz),
installed Debian 4.0 on it and compiled gnucap successfully. So I'm
ready by now :)
I guess reading the gnucap documentation is a good starting point for me.

Changing the circuit interactively is really cool, so one doesn't have
to launch the program over again and again ...
