You would have what is known as the "old beta." FWIW, I can't find it on Tucows anymore. It is officially not available any more, and for a good reason. Similar deal with the manual.
Coldstone has changed quite a bit since the summer of 2000. This is a good thing. There is really no point to playing around with the old beta, there is nothing to be gained by it, because Coldstone has changed so much. Anything you create in it now would have to be completely re-created when Coldstone 1.0 is released.
Also, FWIW, I don't think Andrew or Dee would appreciate people distributing the old manual, it is not available anymore for a reason.
