Many thanks to SWLing Post<\/em> contributor, Grayhat, who writes:<\/p>\n

Maybe it’s old news for you, I just discovered it and thought you may
\nbe interested, the commercial circuit simulator “Micro-Cap 12” which
\nwas sold at around $4,500 for each license is now *free*, I found the
\ninformation here along with some further details:<\/p>\n

https:\/\/hackaday.com\/2020\/01\/08\/commercial-circuit-simulator-goes-free\/<\/a><\/p>\n

The decision of releasing it as freeware seems to be related to the
\nfact that the company selling it (Spectrum Software) closed (not sure
\nfor the reasons); anyhow, since the site or the download link may
\ndisappear in some time, I think it would be a good idea to pick a copy
\nof the software, the full CD image including the program, libraries and
\neverything else can be downloaded from this page<\/p>\n

http:\/\/www.spectrum-soft.com\/download\/download.shtm<\/a><\/strong><\/p>\n

Thank you for the tip! I agree with you about grabbing a full install of the application while you can!<\/p>\n","protected":false},"excerpt":{"rendered":"
