The NEC License v1.5
What is the NEC License?
While working on some programs for the TI-84+CE, we needed to find a way to control where our software was going. Some licenses, such as the MIT license, were too loose and allowed no control anywhere. Other licenses were too strict. We needed a license that allowed modification, but not just direct copies. And thus, the NEC license was born.

What does it mean?
Don't sell the software
Do edit the software
Don't distribute copies
Do distribute versions of the software you have modified or improved upon significantly.
Do use this license in modified versions that you distribute.
Don't blame the developers if something goes wrong.
The author can request removal of copies or modified versions of the software.
Don't license the software to other people using a different license.

Sounds like a great idea.

Will I have to edit the license before using it?

Nope, the license has no license (ok, I guess that means it's ARR, so it's public domain... mmkay)

I'm ok with such licenses, as long as they're not vendor lock-ins in disguise.

DJ_O: I believe KInfinity's original intent is to prevent open-source software from being copied and re-distributed without the author's permission, while still allowing it to be studied and learned from. I'm not sure vendor lock-in is relevant in this case. For what it's worth, the author could also use a more restrictive license, which would prevent the software from being redistributed at all. "All rights reserved" would do that, for instance.

I'm not sure NEC is the best name for this license.

Most initials have another meaning, so although NEC is a major corporation (which I was aware of), this NEC means something different, and I think you can tell the difference pretty easily.

Yeah I am just saying, because in the past, some community members attempted to twist their software licenses and disclaimers in a way that gave 1 single site (or only websites covering 1 specific calculator brand) the exclusive rights to post news articles about it or links to the original download (although one author did that in response to an Omnimaga ban, so that might not count). The main worry that some people have is whether the authors are legitimately trying to protect his intellectual property or instead practicing community website favoritism.
