Many years ago (>25), I used Microcap circuit drawing/simulation package extensively (on a '486 PC, with an early version of Windows) ...our engineering center paid several thousand $$ to get it. Microcap folks were always very helpful & supportive & a class act. They have, of course, improved it along the way, but I was no longer at the same company, so lost track of it. But they continued on over the years.

|Micro-Cap 12 LAN Version ( Per Seat / Two Seat Minimum )||$4495||$4720|
Apparently they went belly up (probably due to competitors like Linear Tech's free simulation offerings). So it was harder to sell for thousands of $$
Anyhow, they did something really COOL, they now say they it's free for anyone who wants it:
Effective 7/4/2019, Spectrum Software is closed. Micro-Cap is now free.
These new versions do not require the security key, so they make Micro-Cap free to the entire engineering community.
Thank you for the honor and privilege of serving you for the last 39 years.
Get it while the website is still around! ...of course there will be no updates & you have to consider whether it is worthwhile to invest your time learning a software that is defunct....but hey, who can resist?
