But that was a fork of
https://github.com/papampi/braiins-os
So most likely, that one is closer.
AFAIK, no versions of the original that I can find though.

Yeah, I guess it's not gone the way the Library of Alexandria lost information. But these two forks aren't really 'active' projects. BrainsOS itself, seemed to have it's github repo deleted for about a year before people noticed (and time of deletion was estimated by use of WayBackMachine) so I suppose it wasn't the most active of projects either.
