Lancer's Reactor, this very same site whose forum you are posting on, has a complete systems / bases list.

Look for "Universe Guide" on the right hand menu after going to the main page.
It does not list base locations though, only on which system they are to be found, so you are on your own to find them.

I already have all of them mapped and could send you my savegame if you think that helps. But finding the locations of hidden bases is part of the fun.

You are right. I have forgotten the pleasure of turning round a planet and seeing a space station and having the status of "unknown". Thanks for reminding me.
