Morphic questions

I tried loading Connectors, but it was not a good experience:

1) There was no published version for any Squeak version.
2) After saying take any version it could find, it was missing a 
prerequisite.  Loading anyway only loaded code that was missing other 
classes.
3) Assuming I did the wrong thing by going to SqueakMap, I went back to 
the SqueakMap page and tried the home page link, only to be told it did 
not exist.

This is not a good testament for Squeak.  I do not know if it is just a 
lot of undocumented magic tricks to make this work, or what.  I would 
really like to use Squeak, but it is getting harder and harder to see 
it as anything more than a collection of unfinished research projects.  
Please help me correct this impression.

Michael
