From another forum (user janoc) so I don't want to take credit but it is a really nice find so I wanted to share it.
From the EULA:The Microcap simulator software is now a free (as in beer) download:
The company is apparently shutting down so they have released the software for free. It is Windows only but it
supposedlyruns in Linux with Wine too.
Nice to have a pretty powerful alternative to LTSpice! "
