I also use a tool that no-one else uses - GALasm, although it's a fairly trivial text file.
I use it, too - it's my favorite assember for GAL/ATF PLDs. I also find its source syntax easier to read than WinCUPL.

I don't expect anyone to ever actually build my SBC, and i'm perfectly ok with that.
but if someone is looking for some examples of how to make a 65816 SBC, they can use my design as a base or use it to look at how i did specific things like the latching circuit to then design their own.
This. I'm often very happy to find someone's SBC with all the sources, since it really helps understand how the thing is supposed to work. I've learned a lot from other people's projects.
I think that's the true spirit of the Open Source, and I've always been trying to make all my works open - not for fame or commendations, but just in case it helps someone as much as similar projects used to help me.
EDIT: Sometimes, the most obscure projects with only few Github stars are the most valuable ones due to their rarity: I recently played with Intel 8008, and I found someone's SBC on Github. That was the only project with a great documentation, schematics and all the sources included, even PLD sources for GAL. Needless to say, it helped me tremendously to understand 8008's internals and usecases.
