Just in case, I uploaded the wiki backup here

Not sure what the mainline status is. The last time I checked, several
years ago, to have an "almost" usable experience some
out-of-tree patches from https://gitlab.com/openezx/openezx were needed.

The repository is a topgit repository. feel free to pop in the #openezx
channel of Freenode for any details.

I reported this discussion on that IRC channel to see if there is anyone
interested. Let's wait a couple of days and then decide.

Thanks,
